AWS Cloud Development Kit Library

The AWS CDK construct library provides APIs to define your CDK application and add CDK constructs to the application.

Usage

Upgrade from CDK 1.x

When upgrading from CDK 1.x, remove all dependencies to individual CDK packages from your dependencies file and follow the rest of the sections.

Installation

To use this package, you need to declare this package and the constructs package as dependencies.

According to the kind of project you are developing:

  • For projects that are CDK libraries, declare them both under the devDependencies and peerDependencies sections.
  • For CDK apps, declare them under the dependencies section only.
Use in your code
Classic import

You can use a classic import to get access to each service namespaces:

// Example automatically generated from non-compiling source. May contain errors.
import "github.com/aws/aws-cdk-go/awscdk"


app := awscdk.NewApp()
stack := awscdk.Newstack(app, jsii.String("TestStack"))

awscdk.Aws_s3.NewBucket(stack, jsii.String("TestBucket"))
Barrel import

Alternatively, you can use "barrel" imports:

// Example automatically generated from non-compiling source. May contain errors.
import "github.com/aws/aws-cdk-go/awscdk"
import "github.com/aws/aws-cdk-go/awscdk"


app := awscdk.NewApp()
stack := awscdk.Newstack(app, jsii.String("TestStack"))

awscdk.NewBucket(stack, jsii.String("TestBucket"))

Stacks and Stages

A Stack is the smallest physical unit of deployment, and maps directly onto a CloudFormation Stack. You define a Stack by defining a subclass of Stack -- let's call it MyStack -- and instantiating the constructs that make up your application in MyStack's constructor. You then instantiate this stack one or more times to define different instances of your application. For example, you can instantiate it once using few and cheap EC2 instances for testing, and once again using more and bigger EC2 instances for production.

When your application grows, you may decide that it makes more sense to split it out across multiple Stack classes. This can happen for a number of reasons:

  • You could be starting to reach the maximum number of resources allowed in a single stack (this is currently 500).
  • You could decide you want to separate out stateful resources and stateless resources into separate stacks, so that it becomes easy to tear down and recreate the stacks that don't have stateful resources.
  • There could be a single stack with resources (like a VPC) that are shared between multiple instances of other stacks containing your applications.

As soon as your conceptual application starts to encompass multiple stacks, it is convenient to wrap them in another construct that represents your logical application. You can then treat that new unit the same way you used to be able to treat a single stack: by instantiating it multiple times for different instances of your application.

You can define a custom subclass of Stage, holding one or more Stacks, to represent a single logical instance of your application.

As a final note: Stacks are not a unit of reuse. They describe physical deployment layouts, and as such are best left to application builders to organize their deployments with. If you want to vend a reusable construct, define it as a subclasses of Construct: the consumers of your construct will decide where to place it in their own stacks.

Stack Synthesizers

Each Stack has a synthesizer, an object that determines how and where the Stack should be synthesized and deployed. The synthesizer controls aspects like:

  • How does the stack reference assets? (Either through CloudFormation parameters the CLI supplies, or because the Stack knows a predefined location where assets will be uploaded).
  • What roles are used to deploy the stack? These can be bootstrapped roles, roles created in some other way, or just the CLI's current credentials.

The following synthesizers are available:

  • DefaultStackSynthesizer: recommended. Uses predefined asset locations and roles created by the modern bootstrap template. Access control is done by controlling who can assume the deploy role. This is the default stack synthesizer in CDKv2.
  • LegacyStackSynthesizer: Uses CloudFormation parameters to communicate asset locations, and the CLI's current permissions to deploy stacks. The is the default stack synthesizer in CDKv1.
  • CliCredentialsStackSynthesizer: Uses predefined asset locations, and the CLI's current permissions.

Each of these synthesizers takes configuration arguments. To configure a stack with a synthesizer, pass it as one of its properties:

// Example automatically generated from non-compiling source. May contain errors.
NewMyStack(app, jsii.String("MyStack"), &stackProps{
	synthesizer: awscdk.NewDefaultStackSynthesizer(&defaultStackSynthesizerProps{
		fileAssetsBucketName: jsii.String("my-orgs-asset-bucket"),
	}),
})

For more information on bootstrapping accounts and customizing synthesis, see Bootstrapping in the CDK Developer Guide.

Nested Stacks

Nested stacks are stacks created as part of other stacks. You create a nested stack within another stack by using the NestedStack construct.

As your infrastructure grows, common patterns can emerge in which you declare the same components in multiple templates. You can separate out these common components and create dedicated templates for them. Then use the resource in your template to reference other templates, creating nested stacks.

For example, assume that you have a load balancer configuration that you use for most of your stacks. Instead of copying and pasting the same configurations into your templates, you can create a dedicated template for the load balancer. Then, you just use the resource to reference that template from within other templates.

The following example will define a single top-level stack that contains two nested stacks: each one with a single Amazon S3 bucket:

// Example automatically generated from non-compiling source. May contain errors.
type myNestedStack struct {
	nestedStack
}

func newMyNestedStack(scope construct, id *string, props nestedStackProps) *myNestedStack {
	this := &myNestedStack{}
	cfn.NewNestedStack_Override(this, scope, id, props)

	s3.NewBucket(this, jsii.String("NestedBucket"))
	return this
}

type myParentStack struct {
	stack
}

func newMyParentStack(scope construct, id *string, props stackProps) *myParentStack {
	this := &myParentStack{}
	newStack_Override(this, scope, id, props)

	NewMyNestedStack(this, jsii.String("Nested1"))
	NewMyNestedStack(this, jsii.String("Nested2"))
	return this
}

Resources references across nested/parent boundaries (even with multiple levels of nesting) will be wired by the AWS CDK through CloudFormation parameters and outputs. When a resource from a parent stack is referenced by a nested stack, a CloudFormation parameter will automatically be added to the nested stack and assigned from the parent; when a resource from a nested stack is referenced by a parent stack, a CloudFormation output will be automatically be added to the nested stack and referenced using Fn::GetAtt "Outputs.Xxx" from the parent.

Nested stacks also support the use of Docker image and file assets.

Accessing resources in a different stack

You can access resources in a different stack, as long as they are in the same account and AWS Region (see next section for an exception). The following example defines the stack stack1, which defines an Amazon S3 bucket. Then it defines a second stack, stack2, which takes the bucket from stack1 as a constructor property.

// Example automatically generated from non-compiling source. May contain errors.
prod := map[string]*string{
	"account": jsii.String("123456789012"),
	"region": jsii.String("us-east-1"),
}

stack1 := NewStackThatProvidesABucket(app, jsii.String("Stack1"), &stackProps{
	env: prod,
})

// stack2 will take a property { bucket: IBucket }
stack2 := NewStackThatExpectsABucket(app, jsii.String("Stack2"), &stackThatExpectsABucketProps{
	bucket: stack1.bucket,
	env: prod,
})

If the AWS CDK determines that the resource is in the same account and Region, but in a different stack, it automatically synthesizes AWS CloudFormation Exports in the producing stack and an Fn::ImportValue in the consuming stack to transfer that information from one stack to the other.

Accessing resources in a different stack and region

This feature is currently experimental

You can enable the Stack property crossRegionReferences in order to access resources in a different stack and region. With this feature flag enabled it is possible to do something like creating a CloudFront distribution in us-east-2 and an ACM certificate in us-east-1.

// Example automatically generated from non-compiling source. May contain errors.
stack1 := awscdk.Newstack(app, jsii.String("Stack1"), &stackProps{
	env: &environment{
		region: jsii.String("us-east-1"),
	},
	crossRegionReferences: jsii.Boolean(true),
})
cert := acm.NewCertificate(stack1, jsii.String("Cert"), &certificateProps{
	domainName: jsii.String("*.example.com"),
	validation: acm.certificateValidation.fromDns(route53.publicHostedZone.fromHostedZoneId(stack1, jsii.String("Zone"), jsii.String("Z0329774B51CGXTDQV3X"))),
})

stack2 := awscdk.Newstack(app, jsii.String("Stack2"), &stackProps{
	env: &environment{
		region: jsii.String("us-east-2"),
	},
	crossRegionReferences: jsii.Boolean(true),
})
cloudfront.NewDistribution(stack2, jsii.String("Distribution"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: origins.NewHttpOrigin(jsii.String("example.com")),
	},
	domainNames: []*string{
		jsii.String("dev.example.com"),
	},
	certificate: cert,
})

When the AWS CDK determines that the resource is in a different stack and is in a different region, it will "export" the value by creating a custom resource in the producing stack which creates SSM Parameters in the consuming region for each exported value. The parameters will be created with the name '/cdk/exports/${consumingStackName}/${export-name}'. In order to "import" the exports into the consuming stack a SSM Dynamic reference is used to reference the SSM parameter which was created.

In order to mimic strong references, a Custom Resource is also created in the consuming stack which marks the SSM parameters as being "imported". When a parameter has been successfully imported, the producing stack cannot update the value.

See the adr for more details on this feature.

Removing automatic cross-stack references

The automatic references created by CDK when you use resources across stacks are convenient, but may block your deployments if you want to remove the resources that are referenced in this way. You will see an error like:

Export Stack1:ExportsOutputFnGetAtt-****** cannot be deleted as it is in use by Stack1

Let's say there is a Bucket in the stack1, and the stack2 references its bucket.bucketName. You now want to remove the bucket and run into the error above.

It's not safe to remove stack1.bucket while stack2 is still using it, so unblocking yourself from this is a two-step process. This is how it works:

DEPLOYMENT 1: break the relationship

  • Make sure stack2 no longer references bucket.bucketName (maybe the consumer stack now uses its own bucket, or it writes to an AWS DynamoDB table, or maybe you just remove the Lambda Function altogether).
  • In the stack1 class, call this.exportValue(this.bucket.bucketName). This will make sure the CloudFormation Export continues to exist while the relationship between the two stacks is being broken.
  • Deploy (this will effectively only change the stack2, but it's safe to deploy both).

DEPLOYMENT 2: remove the resource

  • You are now free to remove the bucket resource from stack1.
  • Don't forget to remove the exportValue() call as well.
  • Deploy again (this time only the stack1 will be changed -- the bucket will be deleted).

Durations

To make specifications of time intervals unambiguous, a single class called Duration is used throughout the AWS Construct Library by all constructs that that take a time interval as a parameter (be it for a timeout, a rate, or something else).

An instance of Duration is constructed by using one of the static factory methods on it:

// Example automatically generated from non-compiling source. May contain errors.
awscdk.Duration.seconds(jsii.Number(300)) // 5 minutes
awscdk.Duration.minutes(jsii.Number(5)) // 5 minutes
awscdk.Duration.hours(jsii.Number(1)) // 1 hour
awscdk.Duration.days(jsii.Number(7)) // 7 days
awscdk.Duration.parse(jsii.String("PT5M"))

Durations can be added or subtracted together:

// Example automatically generated from non-compiling source. May contain errors.
awscdk.Duration.minutes(jsii.Number(1)).plus(awscdk.Duration.seconds(jsii.Number(60))) // 2 minutes
awscdk.Duration.minutes(jsii.Number(5)).minus(awscdk.Duration.seconds(jsii.Number(10)))

Size (Digital Information Quantity)

To make specification of digital storage quantities unambiguous, a class called Size is available.

An instance of Size is initialized through one of its static factory methods:

// Example automatically generated from non-compiling source. May contain errors.
awscdk.Size.kibibytes(jsii.Number(200)) // 200 KiB
awscdk.Size.mebibytes(jsii.Number(5)) // 5 MiB
awscdk.Size.gibibytes(jsii.Number(40)) // 40 GiB
awscdk.Size.tebibytes(jsii.Number(200)) // 200 TiB
awscdk.Size.pebibytes(jsii.Number(3))

Instances of Size created with one of the units can be converted into others. By default, conversion to a higher unit will fail if the conversion does not produce a whole number. This can be overridden by unsetting integral property.

// Example automatically generated from non-compiling source. May contain errors.
awscdk.Size.mebibytes(jsii.Number(2)).toKibibytes() // yields 2048
awscdk.Size.kibibytes(jsii.Number(2050)).toMebibytes(&sizeConversionOptions{
	rounding: awscdk.SizeRoundingBehavior_FLOOR,
})

Secrets

To help avoid accidental storage of secrets as plain text, we use the SecretValue type to represent secrets. Any construct that takes a value that should be a secret (such as a password or an access key) will take a parameter of type SecretValue.

The best practice is to store secrets in AWS Secrets Manager and reference them using SecretValue.secretsManager:

// Example automatically generated from non-compiling source. May contain errors.
secret := awscdk.SecretValue.secretsManager(jsii.String("secretId"), &secretsManagerSecretOptions{
	jsonField: jsii.String("password"),
	 // optional: key of a JSON field to retrieve (defaults to all content),
	versionId: jsii.String("id"),
	 // optional: id of the version (default AWSCURRENT)
	versionStage: jsii.String("stage"),
})

Using AWS Secrets Manager is the recommended way to reference secrets in a CDK app. SecretValue also supports the following secret sources:

  • SecretValue.unsafePlainText(secret): stores the secret as plain text in your app and the resulting template (not recommended).
  • SecretValue.secretsManager(secret): refers to a secret stored in Secrets Manager
  • SecretValue.ssmSecure(param, version): refers to a secret stored as a SecureString in the SSM Parameter Store. If you don't specify the exact version, AWS CloudFormation uses the latest version of the parameter.
  • SecretValue.cfnParameter(param): refers to a secret passed through a CloudFormation parameter (must have NoEcho: true).
  • SecretValue.cfnDynamicReference(dynref): refers to a secret described by a CloudFormation dynamic reference (used by ssmSecure and secretsManager).
  • SecretValue.resourceAttribute(attr): refers to a secret returned from a CloudFormation resource creation.

SecretValues should only be passed to constructs that accept properties of type SecretValue. These constructs are written to ensure your secrets will not be exposed where they shouldn't be. If you try to use a SecretValue in a different location, an error about unsafe secret usage will be thrown at synthesis time.

If you rotate the secret's value in Secrets Manager, you must also change at least one property on the resource where you are using the secret, to force CloudFormation to re-read the secret.

SecretValue.ssmSecure() is only supported for a limited set of resources. Click here for a list of supported resources and properties.

ARN manipulation

Sometimes you will need to put together or pick apart Amazon Resource Names (ARNs). The functions stack.formatArn() and stack.parseArn() exist for this purpose.

formatArn() can be used to build an ARN from components. It will automatically use the region and account of the stack you're calling it on:

// Example automatically generated from non-compiling source. May contain errors.
var stack stack


// Builds "arn:<PARTITION>:lambda:<REGION>:<ACCOUNT>:function:MyFunction"
stack.formatArn(&arnComponents{
	service: jsii.String("lambda"),
	resource: jsii.String("function"),
	sep: jsii.String(":"),
	resourceName: jsii.String("MyFunction"),
})

parseArn() can be used to get a single component from an ARN. parseArn() will correctly deal with both literal ARNs and deploy-time values (tokens), but in case of a deploy-time value be aware that the result will be another deploy-time value which cannot be inspected in the CDK application.

// Example automatically generated from non-compiling source. May contain errors.
var stack stack


// Extracts the function name out of an AWS Lambda Function ARN
arnComponents := stack.parseArn(arn, jsii.String(":"))
functionName := arnComponents.resourceName

Note that depending on the service, the resource separator can be either : or /, and the resource name can be either the 6th or 7th component in the ARN. When using these functions, you will need to know the format of the ARN you are dealing with.

For an exhaustive list of ARN formats used in AWS, see AWS ARNs and Namespaces in the AWS General Reference.

Dependencies

Construct Dependencies

Sometimes AWS resources depend on other resources, and the creation of one resource must be completed before the next one can be started.

In general, CloudFormation will correctly infer the dependency relationship between resources based on the property values that are used. In the cases where it doesn't, the AWS Construct Library will add the dependency relationship for you.

If you need to add an ordering dependency that is not automatically inferred, you do so by adding a dependency relationship using constructA.node.addDependency(constructB). This will add a dependency relationship between all resources in the scope of constructA and all resources in the scope of constructB.

If you want a single object to represent a set of constructs that are not necessarily in the same scope, you can use a DependencyGroup. The following creates a single object that represents a dependency on two constructs, constructB and constructC:

// Example automatically generated from non-compiling source. May contain errors.
// Declare the dependable object
bAndC := constructs.NewDependencyGroup()
bAndC.add(constructB)
bAndC.add(constructC)

// Take the dependency
constructA.node.addDependency(bAndC)
Stack Dependencies

Two different stack instances can have a dependency on one another. This happens when an resource from one stack is referenced in another stack. In that case, CDK records the cross-stack referencing of resources, automatically produces the right CloudFormation primitives, and adds a dependency between the two stacks. You can also manually add a dependency between two stacks by using the stackA.addDependency(stackB) method.

A stack dependency has the following implications:

  • Cyclic dependencies are not allowed, so if stackA is using resources from stackB, the reverse is not possible anymore.

  • Stacks with dependencies between them are treated specially by the CDK toolkit:

    • If stackA depends on stackB, running cdk deploy stackA will also automatically deploy stackB.
    • stackB's deployment will be performed before stackA's deployment.
CfnResource Dependencies

To make declaring dependencies between CfnResource objects easier, you can declare dependencies from one CfnResource object on another by using the cfnResource1.addDependency(cfnResource2) method. This method will work for resources both within the same stack and across stacks as it detects the relative location of the two resources and adds the dependency either to the resource or between the relevant stacks, as appropriate. If more complex logic is in needed, you can similarly remove, replace, or view dependencies between CfnResource objects with the CfnResource removeDependency, replaceDependency, and obtainDependencies methods, respectively.

Custom Resources

Custom Resources are CloudFormation resources that are implemented by arbitrary user code. They can do arbitrary lookups or modifications during a CloudFormation deployment.

Custom resources are backed by custom resource providers. Commonly, these are Lambda Functions that are deployed in the same deployment as the one that defines the custom resource itself, but they can also be backed by Lambda Functions deployed previously, or code responding to SNS Topic events running on EC2 instances in a completely different account. For more information on custom resource providers, see the next section.

Once you have a provider, each definition of a CustomResource construct represents one invocation. A single provider can be used for the implementation of arbitrarily many custom resource definitions. A single definition looks like this:

// Example automatically generated from non-compiling source. May contain errors.
awscdk.NewCustomResource(this, jsii.String("MyMagicalResource"), &customResourceProps{
	resourceType: jsii.String("Custom::MyCustomResource"),
	 // must start with 'Custom::'

	// the resource properties
	properties: map[string]interface{}{
		"Property1": jsii.String("foo"),
		"Property2": jsii.String("bar"),
	},

	// the ARN of the provider (SNS/Lambda) which handles
	// CREATE, UPDATE or DELETE events for this resource type
	// see next section for details
	serviceToken: jsii.String("ARN"),
})
Custom Resource Providers

Custom resources are backed by a custom resource provider which can be implemented in one of the following ways. The following table compares the various provider types (ordered from low-level to high-level):

Provider Compute Type Error Handling Submit to CloudFormation Max Timeout Language Footprint
sns.Topic Self-managed Manual Manual Unlimited Any Depends
lambda.Function AWS Lambda Manual Manual 15min Any Small
core.CustomResourceProvider AWS Lambda Auto Auto 15min Node.js Small
custom-resources.Provider AWS Lambda Auto Auto Unlimited Async Any Large

Legend:

  • Compute type: which type of compute can is used to execute the handler.
  • Error Handling: whether errors thrown by handler code are automatically trapped and a FAILED response is submitted to CloudFormation. If this is "Manual", developers must take care of trapping errors. Otherwise, events could cause stacks to hang.
  • Submit to CloudFormation: whether the framework takes care of submitting SUCCESS/FAILED responses to CloudFormation through the event's response URL.
  • Max Timeout: maximum allows/possible timeout.
  • Language: which programming languages can be used to implement handlers.
  • Footprint: how many resources are used by the provider framework itself.

A NOTE ABOUT SINGLETONS

When defining resources for a custom resource provider, you will likely want to define them as a stack singleton so that only a single instance of the provider is created in your stack and which is used by all custom resources of that type.

Here is a basic pattern for defining stack singletons in the CDK. The following examples ensures that only a single SNS topic is defined:

// Example automatically generated from non-compiling source. May contain errors.
func getOrCreate(scope *construct) topic {
	stack := awscdk.stack.of(*scope)
	uniqueid := "GloballyUniqueIdForSingleton" // For example, a UUID from `uuidgen`
	existing := stack.node.tryFindChild(uniqueid)
	if existing {
		return existing.(topic)
	}
	return sns.NewTopic(stack, uniqueid)
}
Amazon SNS Topic

Every time a resource event occurs (CREATE/UPDATE/DELETE), an SNS notification is sent to the SNS topic. Users must process these notifications (e.g. through a fleet of worker hosts) and submit success/failure responses to the CloudFormation service.

You only need to use this type of provider if your custom resource cannot run on AWS Lambda, for reasons other than the 15 minute timeout. If you are considering using this type of provider because you want to write a custom resource provider that may need to wait for more than 15 minutes for the API calls to stabilize, have a look at the custom-resources module first.

Refer to the CloudFormation Custom Resource documentation for information on the contract your custom resource needs to adhere to.

Set serviceToken to topic.topicArn in order to use this provider:

// Example automatically generated from non-compiling source. May contain errors.
topic := sns.NewTopic(this, jsii.String("MyProvider"))

awscdk.NewCustomResource(this, jsii.String("MyResource"), &customResourceProps{
	serviceToken: topic.topicArn,
})
AWS Lambda Function

An AWS lambda function is called directly by CloudFormation for all resource events. The handler must take care of explicitly submitting a success/failure response to the CloudFormation service and handle various error cases.

We do not recommend you use this provider type. The CDK has wrappers around Lambda Functions that make them easier to work with.

If you do want to use this provider, refer to the CloudFormation Custom Resource documentation for information on the contract your custom resource needs to adhere to.

Set serviceToken to lambda.functionArn to use this provider:

// Example automatically generated from non-compiling source. May contain errors.
fn := lambda.NewFunction(this, jsii.String("MyProvider"), functionProps)

awscdk.NewCustomResource(this, jsii.String("MyResource"), &customResourceProps{
	serviceToken: fn.functionArn,
})
The core.CustomResourceProvider class

The class @aws-cdk/core.CustomResourceProvider offers a basic low-level framework designed to implement simple and slim custom resource providers. It currently only supports Node.js-based user handlers, represents permissions as raw JSON blobs instead of iam.PolicyStatement objects, and it does not have support for asynchronous waiting (handler cannot exceed the 15min lambda timeout).

As an application builder, we do not recommend you use this provider type. This provider exists purely for custom resources that are part of the AWS Construct Library.

The custom-resources provider is more convenient to work with and more fully-featured.

The provider has a built-in singleton method which uses the resource type as a stack-unique identifier and returns the service token:

// Example automatically generated from non-compiling source. May contain errors.
serviceToken := awscdk.CustomResourceProvider.getOrCreate(this, jsii.String("Custom::MyCustomResourceType"), &customResourceProviderProps{
	codeDirectory: fmt.Sprintf("%v/my-handler", __dirname),
	runtime: awscdk.CustomResourceProviderRuntime_NODEJS_14_X,
	description: jsii.String("Lambda function created by the custom resource provider"),
})

awscdk.NewCustomResource(this, jsii.String("MyResource"), &customResourceProps{
	resourceType: jsii.String("Custom::MyCustomResourceType"),
	serviceToken: serviceToken,
})

The directory (my-handler in the above example) must include an index.js file. It cannot import external dependencies or files outside this directory. It must export an async function named handler. This function accepts the CloudFormation resource event object and returns an object with the following structure:

exports.handler = async function(event) {
  const id = event.PhysicalResourceId; // only for "Update" and "Delete"
  const props = event.ResourceProperties;
  const oldProps = event.OldResourceProperties; // only for "Update"s

  switch (event.RequestType) {
    case "Create":
      // ...

    case "Update":
      // ...

      // if an error is thrown, a FAILED response will be submitted to CFN
      throw new Error('Failed!');

    case "Delete":
      // ...
  }

  return {
    // (optional) the value resolved from `resource.ref`
    // defaults to "event.PhysicalResourceId" or "event.RequestId"
    PhysicalResourceId: "REF",

    // (optional) calling `resource.getAtt("Att1")` on the custom resource in the CDK app
    // will return the value "BAR".
    Data: {
      Att1: "BAR",
      Att2: "BAZ"
    },

    // (optional) user-visible message
    Reason: "User-visible message",

    // (optional) hides values from the console
    NoEcho: true
  };
}

Here is an complete example of a custom resource that summarizes two numbers:

sum-handler/index.js:

exports.handler = async (e) => {
  return {
    Data: {
      Result: e.ResourceProperties.lhs + e.ResourceProperties.rhs,
    },
  };
};

sum.ts:

// Example automatically generated from non-compiling source. May contain errors.
import "github.com/aws-samples/dummy/awscdkcore"

type sumProps struct {
	lhs *f64
	rhs *f64
}

type Sum struct {
	Construct
	result *f64
}result *f64

func NewSum(scope Construct, id *string, props sumProps) *Sum {
	this := &Sum{}
	newConstruct_Override(this, scope, id)

	resourceType := "Custom::Sum"
	serviceToken := awscdkcore.CustomResourceProvider.getOrCreate(this, resourceType, &customResourceProviderProps{
		codeDirectory: fmt.Sprintf("%v/sum-handler", __dirname),
		runtime: *awscdkcore.CustomResourceProviderRuntime_NODEJS_14_X,
	})

	resource := awscdkcore.NewCustomResource(this, jsii.String("Resource"), &customResourceProps{
		resourceType: resourceType,
		serviceToken: serviceToken,
		properties: map[string]interface{}{
			"lhs": props.lhs,
			"rhs": props.rhs,
		},
	})

	this.result = awscdkcore.Token.asNumber(resource.getAtt(jsii.String("Result")))
	return this
}

Usage will look like this:

// Example automatically generated from non-compiling source. May contain errors.
sum := NewSum(this, jsii.String("MySum"), &sumProps{
	lhs: jsii.Number(40),
	rhs: jsii.Number(2),
})
awscdk.NewCfnOutput(this, jsii.String("Result"), &cfnOutputProps{
	value: awscdk.Token.asString(sum.result),
})

To access the ARN of the provider's AWS Lambda function role, use the getOrCreateProvider() built-in singleton method:

// Example automatically generated from non-compiling source. May contain errors.
provider := awscdk.CustomResourceProvider.getOrCreateProvider(this, jsii.String("Custom::MyCustomResourceType"), &customResourceProviderProps{
	codeDirectory: fmt.Sprintf("%v/my-handler", __dirname),
	runtime: awscdk.CustomResourceProviderRuntime_NODEJS_14_X,
})

roleArn := provider.roleArn

This role ARN can then be used in resource-based IAM policies.

To add IAM policy statements to this role, use addToRolePolicy():

// Example automatically generated from non-compiling source. May contain errors.
provider := awscdk.CustomResourceProvider.getOrCreateProvider(this, jsii.String("Custom::MyCustomResourceType"), &customResourceProviderProps{
	codeDirectory: fmt.Sprintf("%v/my-handler", __dirname),
	runtime: awscdk.CustomResourceProviderRuntime_NODEJS_14_X,
})
provider.addToRolePolicy(map[string]*string{
	"Effect": jsii.String("Allow"),
	"Action": jsii.String("s3:GetObject"),
	"Resource": jsii.String("*"),
})

Note that addToRolePolicy() uses direct IAM JSON policy blobs, not a iam.PolicyStatement object like you will see in the rest of the CDK.

The Custom Resource Provider Framework

The @aws-cdk/custom-resources module includes an advanced framework for implementing custom resource providers.

Handlers are implemented as AWS Lambda functions, which means that they can be implemented in any Lambda-supported runtime. Furthermore, this provider has an asynchronous mode, which means that users can provide an isComplete lambda function which is called periodically until the operation is complete. This allows implementing providers that can take up to two hours to stabilize.

Set serviceToken to provider.serviceToken to use this type of provider:

// Example automatically generated from non-compiling source. May contain errors.
provider := customresources.NewProvider(this, jsii.String("MyProvider"), &providerProps{
	onEventHandler: onEventHandler,
	isCompleteHandler: isCompleteHandler,
})

awscdk.NewCustomResource(this, jsii.String("MyResource"), &customResourceProps{
	serviceToken: provider.serviceToken,
})

See the documentation for more details.

AWS CloudFormation features

A CDK stack synthesizes to an AWS CloudFormation Template. This section explains how this module allows users to access low-level CloudFormation features when needed.

Stack Outputs

CloudFormation stack outputs and exports are created using the CfnOutput class:

// Example automatically generated from non-compiling source. May contain errors.
awscdk.NewCfnOutput(this, jsii.String("OutputName"), &cfnOutputProps{
	value: myBucket.bucketName,
	description: jsii.String("The name of an S3 bucket"),
	 // Optional
	exportName: jsii.String("TheAwesomeBucket"),
})
Parameters

CloudFormation templates support the use of Parameters to customize a template. They enable CloudFormation users to input custom values to a template each time a stack is created or updated. While the CDK design philosophy favors using build-time parameterization, users may need to use CloudFormation in a number of cases (for example, when migrating an existing stack to the AWS CDK).

Template parameters can be added to a stack by using the CfnParameter class:

// Example automatically generated from non-compiling source. May contain errors.
awscdk.NewCfnParameter(this, jsii.String("MyParameter"), &cfnParameterProps{
	type: jsii.String("Number"),
	default: jsii.Number(1337),
})

The value of parameters can then be obtained using one of the value methods. As parameters are only resolved at deployment time, the values obtained are placeholder tokens for the real value (Token.isUnresolved() would return true for those):

// Example automatically generated from non-compiling source. May contain errors.
param := awscdk.NewCfnParameter(this, jsii.String("ParameterName"), &cfnParameterProps{
})

// If the parameter is a String
param.valueAsString

// If the parameter is a Number
param.valueAsNumber

// If the parameter is a List
param.valueAsList
Pseudo Parameters

CloudFormation supports a number of pseudo parameters, which resolve to useful values at deployment time. CloudFormation pseudo parameters can be obtained from static members of the Aws class.

It is generally recommended to access pseudo parameters from the scope's stack instead, which guarantees the values produced are qualifying the designated stack, which is essential in cases where resources are shared cross-stack:

// Example automatically generated from non-compiling source. May contain errors.
// "this" is the current construct
stack := awscdk.stack.of(this)

stack.account // Returns the AWS::AccountId for this stack (or the literal value if known)
stack.region // Returns the AWS::Region for this stack (or the literal value if known)
stack.partition
Resource Options

CloudFormation resources can also specify resource attributes. The CfnResource class allows accessing those through the cfnOptions property:

// Example automatically generated from non-compiling source. May contain errors.
rawBucket := s3.NewCfnBucket(this, jsii.String("Bucket"), &cfnBucketProps{
})
// -or-
rawBucketAlt := myBucket.node.defaultChild.(cfnBucket)

// then
rawBucket.cfnOptions.condition = awscdk.NewCfnCondition(this, jsii.String("EnableBucket"), &cfnConditionProps{
})
rawBucket.cfnOptions.metadata = map[string]interface{}{
	"metadataKey": jsii.String("MetadataValue"),
}

Resource dependencies (the DependsOn attribute) is modified using the cfnResource.addDependency method:

// Example automatically generated from non-compiling source. May contain errors.
resourceA := awscdk.NewCfnResource(this, jsii.String("ResourceA"), resourceProps)
resourceB := awscdk.NewCfnResource(this, jsii.String("ResourceB"), resourceProps)

resourceB.addDependency(resourceA)
Intrinsic Functions and Condition Expressions

CloudFormation supports intrinsic functions. These functions can be accessed from the Fn class, which provides type-safe methods for each intrinsic function as well as condition expressions:

// Example automatically generated from non-compiling source. May contain errors.
var myObjectOrArray interface{}
var myArray interface{}


// To use Fn::Base64
awscdk.Fn.base64(jsii.String("SGVsbG8gQ0RLIQo="))

// To compose condition expressions:
environmentParameter := awscdk.NewCfnParameter(this, jsii.String("Environment"))
awscdk.Fn.conditionAnd(awscdk.Fn.conditionEquals(jsii.String("Production"), environmentParameter), awscdk.Fn.conditionNot(awscdk.Fn.conditionEquals(jsii.String("us-east-1"), awscdk.Aws_REGION())))

// To use Fn::ToJsonString
awscdk.Fn.toJsonString(myObjectOrArray)

// To use Fn::Length
awscdk.Fn.len(awscdk.Fn.split(jsii.String(","), myArray))

When working with deploy-time values (those for which Token.isUnresolved returns true), idiomatic conditionals from the programming language cannot be used (the value will not be known until deployment time). When conditional logic needs to be expressed with un-resolved values, it is necessary to use CloudFormation conditions by means of the CfnCondition class:

// Example automatically generated from non-compiling source. May contain errors.
environmentParameter := awscdk.NewCfnParameter(this, jsii.String("Environment"))
isProd := awscdk.NewCfnCondition(this, jsii.String("IsProduction"), &cfnConditionProps{
	expression: awscdk.Fn.conditionEquals(jsii.String("Production"), environmentParameter),
})

// Configuration value that is a different string based on IsProduction
stage := awscdk.Fn.conditionIf(isProd.logicalId, jsii.String("Beta"), jsii.String("Prod")).toString()

// Make Bucket creation condition to IsProduction by accessing
// and overriding the CloudFormation resource
bucket := s3.NewBucket(this, jsii.String("Bucket"))
cfnBucket := myBucket.node.defaultChild.(cfnBucket)
cfnBucket.cfnOptions.condition = isProd
Mappings

CloudFormation mappings are created and queried using the CfnMappings class:

// Example automatically generated from non-compiling source. May contain errors.
regionTable := awscdk.NewCfnMapping(this, jsii.String("RegionTable"), &cfnMappingProps{
	mapping: map[string]map[string]interface{}{
		"us-east-1": map[string]interface{}{
			"regionName": jsii.String("US East (N. Virginia)"),
		},
		"us-east-2": map[string]interface{}{
			"regionName": jsii.String("US East (Ohio)"),
		},
	},
})

regionTable.findInMap(awscdk.Aws_REGION(), jsii.String("regionName"))

This will yield the following template:

Mappings:
  RegionTable:
    us-east-1:
      regionName: US East (N. Virginia)
    us-east-2:
      regionName: US East (Ohio)

Mappings can also be synthesized "lazily"; lazy mappings will only render a "Mappings" section in the synthesized CloudFormation template if some findInMap call is unable to immediately return a concrete value due to one or both of the keys being unresolved tokens (some value only available at deploy-time).

For example, the following code will not produce anything in the "Mappings" section. The call to findInMap will be able to resolve the value during synthesis and simply return 'US East (Ohio)'.

// Example automatically generated from non-compiling source. May contain errors.
regionTable := awscdk.NewCfnMapping(this, jsii.String("RegionTable"), &cfnMappingProps{
	mapping: map[string]map[string]interface{}{
		"us-east-1": map[string]interface{}{
			"regionName": jsii.String("US East (N. Virginia)"),
		},
		"us-east-2": map[string]interface{}{
			"regionName": jsii.String("US East (Ohio)"),
		},
	},
	lazy: jsii.Boolean(true),
})

regionTable.findInMap(jsii.String("us-east-2"), jsii.String("regionName"))

On the other hand, the following code will produce the "Mappings" section shown above, since the top-level key is an unresolved token. The call to findInMap will return a token that resolves to { "Fn::FindInMap": [ "RegionTable", { "Ref": "AWS::Region" }, "regionName" ] }.

// Example automatically generated from non-compiling source. May contain errors.
var regionTable cfnMapping


regionTable.findInMap(awscdk.Aws_REGION(), jsii.String("regionName"))
Dynamic References

CloudFormation supports dynamically resolving values for SSM parameters (including secure strings) and Secrets Manager. Encoding such references is done using the CfnDynamicReference class:

// Example automatically generated from non-compiling source. May contain errors.
awscdk.NewCfnDynamicReference(awscdk.CfnDynamicReferenceService_SECRETS_MANAGER, jsii.String("secret-id:secret-string:json-key:version-stage:version-id"))
Template Options & Transform

CloudFormation templates support a number of options, including which Macros or Transforms to use when deploying the stack. Those can be configured using the stack.templateOptions property:

// Example automatically generated from non-compiling source. May contain errors.
stack := awscdk.Newstack(app, jsii.String("StackName"))

stack.templateOptions.description = "This will appear in the AWS console"
stack.templateOptions.transforms = []*string{
	"AWS::Serverless-2016-10-31",
}
stack.templateOptions.metadata = map[string]interface{}{
	"metadataKey": jsii.String("MetadataValue"),
}
Emitting Raw Resources

The CfnResource class allows emitting arbitrary entries in the Resources section of the CloudFormation template.

// Example automatically generated from non-compiling source. May contain errors.
awscdk.NewCfnResource(this, jsii.String("ResourceId"), &cfnResourceProps{
	type: jsii.String("AWS::S3::Bucket"),
	properties: map[string]interface{}{
		"BucketName": jsii.String("bucket-name"),
	},
})

As for any other resource, the logical ID in the CloudFormation template will be generated by the AWS CDK, but the type and properties will be copied verbatim in the synthesized template.

Including raw CloudFormation template fragments

When migrating a CloudFormation stack to the AWS CDK, it can be useful to include fragments of an existing template verbatim in the synthesized template. This can be achieved using the CfnInclude class.

// Example automatically generated from non-compiling source. May contain errors.
awscdk.NewCfnInclude(this, jsii.String("ID"), &cfnIncludeProps{
	template: map[string]map[string]map[string]interface{}{
		"Resources": map[string]map[string]interface{}{
			"Bucket": map[string]interface{}{
				"Type": jsii.String("AWS::S3::Bucket"),
				"Properties": map[string]*string{
					"BucketName": jsii.String("my-shiny-bucket"),
				},
			},
		},
	},
})
Termination Protection

You can prevent a stack from being accidentally deleted by enabling termination protection on the stack. If a user attempts to delete a stack with termination protection enabled, the deletion fails and the stack--including its status--remains unchanged. Enabling or disabling termination protection on a stack sets it for any nested stacks belonging to that stack as well. You can enable termination protection on a stack by setting the terminationProtection prop to true.

// Example automatically generated from non-compiling source. May contain errors.
stack := awscdk.Newstack(app, jsii.String("StackName"), &stackProps{
	terminationProtection: jsii.Boolean(true),
})

By default, termination protection is disabled.

Description

You can add a description of the stack in the same way as StackProps.

// Example automatically generated from non-compiling source. May contain errors.
stack := awscdk.Newstack(app, jsii.String("StackName"), &stackProps{
	description: jsii.String("This is a description."),
})
CfnJson

CfnJson allows you to postpone the resolution of a JSON blob from deployment-time. This is useful in cases where the CloudFormation JSON template cannot express a certain value.

A common example is to use CfnJson in order to render a JSON map which needs to use intrinsic functions in keys. Since JSON map keys must be strings, it is impossible to use intrinsics in keys and CfnJson can help.

The following example defines an IAM role which can only be assumed by principals that are tagged with a specific tag.

// Example automatically generated from non-compiling source. May contain errors.
tagParam := awscdk.NewCfnParameter(this, jsii.String("TagName"))

stringEquals := awscdk.NewCfnJson(this, jsii.String("ConditionJson"), &cfnJsonProps{
	value: map[string]*bool{
		fmt.Sprintf("aws:PrincipalTag/%v", tagParam.valueAsString): jsii.Boolean(true),
	},
})

principal := iam.NewAccountRootPrincipal().withConditions(map[string]interface{}{
	"StringEquals": stringEquals,
})

iam.NewRole(this, jsii.String("MyRole"), &roleProps{
	assumedBy: principal,
})

Explanation: since in this example we pass the tag name through a parameter, it can only be resolved during deployment. The resolved value can be represented in the template through a { "Ref": "TagName" }. However, since we want to use this value inside a aws:PrincipalTag/TAG-NAME IAM operator, we need it in the key of a StringEquals condition. JSON keys must be strings, so to circumvent this limitation, we use CfnJson to "delay" the rendition of this template section to deploy-time. This means that the value of StringEquals in the template will be { "Fn::GetAtt": [ "ConditionJson", "Value" ] }, and will only "expand" to the operator we synthesized during deployment.

Stack Resource Limit

When deploying to AWS CloudFormation, it needs to keep in check the amount of resources being added inside a Stack. Currently it's possible to check the limits in the AWS CloudFormation quotas page.

It's possible to synthesize the project with more Resources than the allowed (or even reduce the number of Resources).

Set the context key @aws-cdk/core:stackResourceLimit with the proper value, being 0 for disable the limit of resources.

App Context

Context values are key-value pairs that can be associated with an app, stack, or construct. One common use case for context is to use it for enabling/disabling feature flags. There are several places where context can be specified. They are listed below in the order they are evaluated (items at the top take precedence over those below).

  • The node.setContext() method
  • The postCliContext prop when you create an App
  • The CLI via the --context CLI argument
  • The cdk.json file via the context key:
  • The cdk.context.json file:
  • The ~/.cdk.json file via the context key:
  • The context prop when you create an App
Examples of setting context
// Example automatically generated from non-compiling source. May contain errors.
awscdk.NewApp(&appProps{
	context: map[string]interface{}{
		"@aws-cdk/core:newStyleStackSynthesis": jsii.Boolean(true),
	},
})

// Example automatically generated from non-compiling source. May contain errors.
app := awscdk.NewApp()
app.node.setContext(jsii.String("@aws-cdk/core:newStyleStackSynthesis"), jsii.Boolean(true))

// Example automatically generated from non-compiling source. May contain errors.
awscdk.NewApp(&appProps{
	postCliContext: map[string]interface{}{
		"@aws-cdk/core:newStyleStackSynthesis": jsii.Boolean(true),
	},
})

cdk synth --context @aws-cdk/core:newStyleStackSynthesis=true

cdk.json

{
  "context": {
    "@aws-cdk/core:newStyleStackSynthesis": true
  }
}

cdk.context.json

{
  "@aws-cdk/core:newStyleStackSynthesis": true
}

~/.cdk.json

{
  "context": {
    "@aws-cdk/core:newStyleStackSynthesis": true
  }
}

IAM Permissions Boundary

It is possible to apply an IAM permissions boundary to all roles within a specific construct scope. The most common use case would be to apply a permissions boundary at the Stage level.

// Example automatically generated from non-compiling source. May contain errors.
var app app


prodStage := awscdk.NewStage(app, jsii.String("ProdStage"), &stageProps{
	permissionsBoundary: permissionsBoundary_FromName(jsii.String("cdk-${Qualifier}-PermissionsBoundary")),
})

Any IAM Roles or Users created within this Stage will have the default permissions boundary attached.

For more details see the Permissions Boundary section in the IAM guide.

Functions ¶

func App_IsApp ¶ 

func App_IsApp(obj interface{}) *bool

Checks if an object is an instance of the `App` class.

Returns: `true` if `obj` is an `App`.

func App_IsConstruct ¶ 

func App_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`.

func App_IsStage ¶ 

func App_IsStage(x interface{}) *bool

Test whether the given construct is a stage.

func Arn_ExtractResourceName ¶ 

func Arn_ExtractResourceName(arn *string, resourceType *string) *string

Extract the full resource name from an ARN.

Necessary for resource names (paths) that may contain the separator, like `arn:aws:iam::111111111111:role/path/to/role/name`.

Only works if we statically know the expected `resourceType` beforehand, since we're going to use that to split the string on ':<resourceType>/' (and take the right-hand side).

We can't extract the 'resourceType' from the ARN at hand, because CloudFormation Expressions only allow literals in the 'separator' argument to `{ Fn::Split }`, and so it can't be `{ Fn::Select: [5, { Fn::Split: [':', ARN] }}`.

Only necessary for ARN formats for which the type-name separator is `/`.

func Arn_Format ¶ 

func Arn_Format(components *ArnComponents, stack Stack) *string

Creates an ARN from components.

If `partition`, `region` or `account` are not specified, the stack's partition, region and account will be used.

If any component is the empty string, an empty string will be inserted into the generated ARN at the location that component corresponds to.

The ARN will be formatted as follows: 

arn:{partition}:{service}:{region}:{account}:{resource}{sep}{resource-name}

The required ARN pieces that are omitted will be taken from the stack that the 'scope' is attached to. If all ARN pieces are supplied, the supplied scope can be 'undefined'.

func AssetStaging_BUNDLING_INPUT_DIR ¶ 

func AssetStaging_BUNDLING_INPUT_DIR() *string

func AssetStaging_BUNDLING_OUTPUT_DIR ¶ 

func AssetStaging_BUNDLING_OUTPUT_DIR() *string

func AssetStaging_ClearAssetHashCache()

Clears the asset hash cache.

func AssetStaging_IsConstruct ¶ 

func AssetStaging_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably.

func CfnPublicTypeVersion_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Because customers have access to different Availability Zones, the intrinsic function “Fn::GetAZs“ enables template authors to write templates that adapt to the calling user's access. That way you don't have to hard-code a full list of Availability Zones for a specified region.

Returns: a token represented as a string array.

func Fn_ImportListValue ¶ 

func Fn_ImportListValue(sharedValueToImport *string, assumedLength *float64, delimiter *string) *[]*string

Like `Fn.importValue`, but import a list with a known length.

If you explicitly want a list with an unknown length, call `Fn.split(',', Fn.importValue(exportName))`. See the documentation of `Fn.split` to read more about the limitations of using lists of unknown length.

`Fn.importListValue(exportName, assumedLength)` is the same as `Fn.split(',', Fn.importValue(exportName), assumedLength)`, but easier to read and impossible to forget to pass `assumedLength`.

func Fn_Split ¶ 

func Fn_Split(delimiter *string, source *string, assumedLength *float64) *[]*string

Split a string token into a token list of string values.

Specify the location of splits with a delimiter such as ',' (a comma). Renders to the `Fn::Split` intrinsic function.

Lists with unknown lengths (default) -------------------------------------

Since this function is used to work with deploy-time values, if `assumedLength` is not given the CDK cannot know the length of the resulting list at synthesis time. This brings the following restrictions:

  • You must use `Fn.select(i, list)` to pick elements out of the list (you must not use `list[i]`).
  • You cannot add elements to the list, remove elements from the list, combine two such lists together, or take a slice of the list.
  • You cannot pass the list to constructs that do any of the above.

The only valid operation with such a tokenized list is to pass it unmodified to a CloudFormation Resource construct.

Lists with assumed lengths --------------------------

Pass `assumedLength` if you know the length of the list that will be produced by splitting. The actual list length at deploy time may be *longer* than the number you pass, but not *shorter*.

The returned list will look like:

``` [Fn.select(0, split), Fn.select(1, split), Fn.select(2, split), ...] ```

The restrictions from the section "Lists with unknown lengths" will now be lifted, at the expense of having to know and fix the length of the list.

Returns: a token represented as a string array.

func Fn_Sub ¶ 

func Fn_Sub(body *string, variables *map[string]*string) *string

The intrinsic function “Fn::Sub“ substitutes variables in an input string with values that you specify.

In your templates, you can use this function to construct commands or outputs that include values that aren't available until you create or update a stack.

Returns: a token represented as a string.

func Lazy_List ¶ 

func Lazy_List(producer IStableListProducer, options *LazyListValueOptions) *[]*string

Defer the one-time calculation of a list value to synthesis time.

Use this if you want to render a list to a template whose actual value depends on some state mutation that may happen after the construct has been created.

If you are simply looking to force a value to a `string[]` type and don't need the calculation to be deferred, use `Token.asList()` instead.

The inner function will only be invoked once, and the resolved value cannot depend on the Stack the Token is used in.

func Lazy_Number ¶ 

func Lazy_Number(producer IStableNumberProducer) *float64

Defer the one-time calculation of a number value to synthesis time.

Use this if you want to render a number to a template whose actual value depends on some state mutation that may happen after the construct has been created.

If you are simply looking to force a value to a `number` type and don't need the calculation to be deferred, use `Token.asNumber()` instead.

The inner function will only be invoked once, and the resolved value cannot depend on the Stack the Token is used in.

func Lazy_String ¶ 

func Lazy_String(producer IStableStringProducer, options *LazyStringValueOptions) *string

Defer the one-time calculation of a string value to synthesis time.

Use this if you want to render a string to a template whose actual value depends on some state mutation that may happen after the construct has been created.

If you are simply looking to force a value to a `string` type and don't need the calculation to be deferred, use `Token.asString()` instead.

The inner function will only be invoked once, and the resolved value cannot depend on the Stack the Token is used in.

func Lazy_UncachedList ¶ 

func Lazy_UncachedList(producer IListProducer, options *LazyListValueOptions) *[]*string

Defer the calculation of a list value to synthesis time.

Use of this function is not recommended; unless you know you need it for sure, you probably don't. Use `Lazy.list()` instead.

The inner function may be invoked multiple times during synthesis. You should only use this method if the returned value depends on variables that may change during the Aspect application phase of synthesis, or if the value depends on the Stack the value is being used in. Both of these cases are rare, and only ever occur for AWS Construct Library authors.

func Lazy_UncachedNumber ¶ 

func Lazy_UncachedNumber(producer INumberProducer) *float64

Defer the calculation of a number value to synthesis time.

Use of this function is not recommended; unless you know you need it for sure, you probably don't. Use `Lazy.number()` instead.

The inner function may be invoked multiple times during synthesis. You should only use this method if the returned value depends on variables that may change during the Aspect application phase of synthesis, or if the value depends on the Stack the value is being used in. Both of these cases are rare, and only ever occur for AWS Construct Library authors.

func Lazy_UncachedString ¶ 

func Lazy_UncachedString(producer IStringProducer, options *LazyStringValueOptions) *string

Defer the calculation of a string value to synthesis time.

Use of this function is not recommended; unless you know you need it for sure, you probably don't. Use `Lazy.string()` instead.

The inner function may be invoked multiple times during synthesis. You should only use this method if the returned value depends on variables that may change during the Aspect application phase of synthesis, or if the value depends on the Stack the value is being used in. Both of these cases are rare, and only ever occur for AWS Construct Library authors.

func Names_NodeUniqueId ¶ 

func Names_NodeUniqueId(node constructs.Node) *string

Returns a CloudFormation-compatible unique identifier for a construct based on its path.

The identifier includes a human readable portion rendered from the path components and a hash suffix.

TODO (v2): replace with API to use `constructs.Node`.

Returns: a unique id based on the construct path.

func Names_UniqueId ¶ 

func Names_UniqueId(construct constructs.IConstruct) *string

Returns a CloudFormation-compatible unique identifier for a construct based on its path.

The identifier includes a human readable portion rendered from the path components and a hash suffix. uniqueId is not unique if multiple copies of the stack are deployed. Prefer using uniqueResourceName().

Returns: a unique id based on the construct path.

func Names_UniqueResourceName ¶ added in v2.29.0 

func Names_UniqueResourceName(construct constructs.IConstruct, options *UniqueResourceNameOptions) *string

Returns a CloudFormation-compatible unique identifier for a construct based on its path.

This function finds the stackName of the parent stack (non-nested) to the construct, and the ids of the components in the construct path.

The user can define allowed special characters, a separator between the elements, and the maximum length of the resource name. The name includes a human readable portion rendered from the path components, with or without user defined separators, and a hash suffix. If the resource name is longer than the maximum length, it is trimmed in the middle.

Returns: a unique resource name based on the construct path.

func NestedStack_IsConstruct ¶ 

func NestedStack_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`.

func NestedStack_IsNestedStack ¶ 

func NestedStack_IsNestedStack(x interface{}) *bool

Checks if `x` is an object of type `NestedStack`.

func NestedStack_IsStack ¶ 

func NestedStack_IsStack(x interface{}) *bool

Return whether the given object is a Stack.

We do attribute detection since we can't reliably use 'instanceof'.

func Resource_IsConstruct ¶ 

func Resource_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`.

func Stack_IsConstruct ¶ 

func Stack_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably.

Returns: true if `x` is an object created from a class which extends `Construct`.

func Stack_IsStack ¶ 

func Stack_IsStack(x interface{}) *bool

Return whether the given object is a Stack.

We do attribute detection since we can't reliably use 'instanceof'.

func Stage_IsConstruct ¶ 

func Stage_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably.

func Token_AsNumber(value interface{}) *float64

Return a reversible number representation of this token.

func Token_AsString ¶ 

func Token_AsString(value interface{}, options *EncodingOptions) *string

Return a reversible string representation of this token.

If the Token is initialized with a literal, the stringified value of the literal is returned. Otherwise, a special quoted string representation of the Token is returned that can be embedded into other strings.

Strings with quoted Tokens in them can be restored back into complex values with the Tokens restored by calling `resolve()` on the string.

func Token_IsUnresolved ¶ 

func Token_IsUnresolved(obj interface{}) *bool

Returns true if obj represents an unresolved value.

One of these must be true:

- `obj` is an IResolvable - `obj` is a string containing at least one encoded `IResolvable` - `obj` is either an encoded number or list

This does NOT recurse into lists or objects to see if they containing resolvables.

func Tokenization_IsResolvable ¶ 

func Tokenization_IsResolvable(obj interface{}) *bool

Return whether the given object is an IResolvable object.

This is different from Token.isUnresolved() which will also check for encoded Tokens, whereas this method will only do a type check on the given object.

func Tokenization_Resolve ¶ 

func Tokenization_Resolve(obj interface{}, options *ResolveOptions) interface{}

Resolves an object by evaluating all tokens and removing any undefined or empty objects or arrays.

Values can only be primitives, arrays or tokens. Other objects (i.e. with methods) will be rejected.

func Tokenization_StringifyNumber ¶ 

func Tokenization_StringifyNumber(x *float64) *string

Stringify a number directly or lazily if it's a Token.

If it is an object (i.e., { Ref: 'SomeLogicalId' }), return it as-is.

Types ¶

type Annotations ¶ 

type Annotations interface {
	// Adds a deprecation warning for a specific API.
	//
	// Deprecations will be added only once per construct as a warning and will be
	// deduplicated based on the `api`.
	//
	// If the environment variable `CDK_BLOCK_DEPRECATIONS` is set, this method
	// will throw an error instead with the deprecation message.
	AddDeprecation(api *string, message *string)
	// Adds an { "error": <message> } metadata entry to this construct.
	//
	// The toolkit will fail deployment of any stack that has errors reported against it.
	AddError(message *string)
	// Adds an info metadata entry to this construct.
	//
	// The CLI will display the info message when apps are synthesized.
	AddInfo(message *string)
	// Adds a warning metadata entry to this construct.
	//
	// The CLI will display the warning when an app is synthesized, or fail if run
	// in --strict mode.
	AddWarning(message *string)
}

Includes API for attaching annotations such as warning messages to constructs.

Example: 

import cdk "github.com/aws/aws-cdk-go/awscdk"
import "github.com/aws/constructs-go/constructs"

type myAspect struct {
}

func (this *myAspect) visit(node iConstruct) {
	if *node instanceof cdk.cfnResource && *node.cfnResourceType == "Foo::Bar" {
		this.error(*node, jsii.String("we do not want a Foo::Bar resource"))
	}
}

func (this *myAspect) error(node iConstruct, message *string) {
	cdk.annotations.of(*node).addError(*message)
}

type myStack struct {
	stack
}

func newMyStack(scope construct, id *string) *myStack {
	this := &myStack{}
	cdk.NewStack_Override(this, scope, id)

	stack := cdk.NewStack()
	cdk.NewCfnResource(stack, jsii.String("Foo"), &cfnResourceProps{
		type: jsii.String("Foo::Bar"),
		properties: map[string]interface{}{
			"Fred": jsii.String("Thud"),
		},
	})
	cdk.aspects.of(stack).add(NewMyAspect())
	return this
}

func Annotations_Of ¶ 

func Annotations_Of(scope constructs.IConstruct) Annotations

Returns the annotations API for a construct scope.

type App ¶ 

type App interface {
	Stage
	// The default account for all resources defined within this stage.
	Account() *string
	// Artifact ID of the assembly if it is a nested stage. The root stage (app) will return an empty string.
	//
	// Derived from the construct path.
	ArtifactId() *string
	// The cloud assembly asset output directory.
	AssetOutdir() *string
	// The tree node.
	Node() constructs.Node
	// The cloud assembly output directory.
	Outdir() *string
	// The parent stage or `undefined` if this is the app.
	//
	// *.
	ParentStage() Stage
	// The default region for all resources defined within this stage.
	Region() *string
	// The name of the stage.
	//
	// Based on names of the parent stages separated by
	// hypens.
	StageName() *string
	// Synthesize this stage into a cloud assembly.
	//
	// Once an assembly has been synthesized, it cannot be modified. Subsequent
	// calls will return the same assembly.
	Synth(options *StageSynthesisOptions) cxapi.CloudAssembly
	// Returns a string representation of this construct.
	ToString() *string
}

A construct which represents an entire CDK app. This construct is normally the root of the construct tree.

You would normally define an `App` instance in your program's entrypoint, then define constructs where the app is used as the parent scope.

After all the child constructs are defined within the app, you should call `app.synth()` which will emit a "cloud assembly" from this app into the directory specified by `outdir`. Cloud assemblies includes artifacts such as CloudFormation templates and assets that are needed to deploy this app into the AWS cloud.

Example: 

import cdk "github.com/aws/aws-cdk-go/awscdk"
import servicediscovery "github.com/aws/aws-cdk-go/awscdk"

app := cdk.NewApp()
stack := cdk.NewStack(app, jsii.String("aws-servicediscovery-integ"))

namespace := servicediscovery.NewPublicDnsNamespace(stack, jsii.String("Namespace"), &publicDnsNamespaceProps{
	name: jsii.String("foobar.com"),
})

service := namespace.createService(jsii.String("Service"), &dnsServiceProps{
	name: jsii.String("foo"),
	dnsRecordType: servicediscovery.dnsRecordType_A,
	dnsTtl: cdk.duration.seconds(jsii.Number(30)),
	healthCheck: &healthCheckConfig{
		type: servicediscovery.healthCheckType_HTTPS,
		resourcePath: jsii.String("/healthcheck"),
		failureThreshold: jsii.Number(2),
	},
})

service.registerIpInstance(jsii.String("IpInstance"), &ipInstanceBaseProps{
	ipv4: jsii.String("54.239.25.192"),
	port: jsii.Number(443),
})

app.synth()

	//
	// This property is recommended over the {@link AppProps.context} property since you
	// can make final decision over which context value to take in your app.
	//

	},
})

type Arn ¶ 

type Arn interface {
}

type ArnComponents ¶ 

type ArnComponents struct {
	// Resource type (e.g. "table", "autoScalingGroup", "certificate"). For some resource types, e.g. S3 buckets, this field defines the bucket name.
	Resource *string `field:"required" json:"resource" yaml:"resource"`
	// The service namespace that identifies the AWS product (for example, 's3', 'iam', 'codepipline').
	Service *string `field:"required" json:"service" yaml:"service"`
	// The ID of the AWS account that owns the resource, without the hyphens.
	//
	// For example, 123456789012. Note that the ARNs for some resources don't
	// require an account number, so this component might be omitted.
	Account *string `field:"optional" json:"account" yaml:"account"`
	// The specific ARN format to use for this ARN value.
	ArnFormat ArnFormat `field:"optional" json:"arnFormat" yaml:"arnFormat"`
	// The partition that the resource is in.
	//
	// For standard AWS regions, the
	// partition is aws. If you have resources in other partitions, the
	// partition is aws-partitionname. For example, the partition for resources
	// in the China (Beijing) region is aws-cn.
	Partition *string `field:"optional" json:"partition" yaml:"partition"`
	// The region the resource resides in.
	//
	// Note that the ARNs for some resources
	// do not require a region, so this component might be omitted.
	Region *string `field:"optional" json:"region" yaml:"region"`
	// Resource name or path within the resource (i.e. S3 bucket object key) or a wildcard such as “"*"“. This is service-dependent.
	ResourceName *string `field:"optional" json:"resourceName" yaml:"resourceName"`
}

Example: 

subZone := route53.NewPublicHostedZone(this, jsii.String("SubZone"), &publicHostedZoneProps{
	zoneName: jsii.String("sub.someexample.com"),
})

// import the delegation role by constructing the roleArn
delegationRoleArn := awscdk.stack.of(this).formatArn(&arnComponents{

	delegationRole: delegationRole,
})

func Arn_Split ¶ 

func Arn_Split(arn *string, arnFormat ArnFormat) *ArnComponents

Splits the provided ARN into its components.

Works both if 'arn' is a string like 'arn:aws:s3:::bucket', and a Token representing a dynamic CloudFormation expression (in which case the returned components will also be dynamic CloudFormation expressions, encoded as Tokens).

type ArnFormat ¶ 

type ArnFormat string

An enum representing the various ARN formats that different services use. 

const (
	// This represents a format where there is no 'resourceName' part.
	//
	// This format is used for S3 resources,
	// like 'arn:aws:s3:::bucket'.
	// Everything after the last colon is considered the 'resource',
	// even if it contains slashes,
	// like in 'arn:aws:s3:::bucket/object.zip'.
	ArnFormat_NO_RESOURCE_NAME ArnFormat = "NO_RESOURCE_NAME"
	// This represents a format where the 'resource' and 'resourceName' parts are separated with a colon.
	//
	// Like in: 'arn:aws:service:region:account:resource:resourceName'.
	// Everything after the last colon is considered the 'resourceName',
	// even if it contains slashes,
	// like in 'arn:aws:apigateway:region:account:resource:/test/mydemoresource/*'.
	ArnFormat_COLON_RESOURCE_NAME ArnFormat = "COLON_RESOURCE_NAME"
	// This represents a format where the 'resource' and 'resourceName' parts are separated with a slash.
	//
	// Like in: 'arn:aws:service:region:account:resource/resourceName'.
	// Everything after the separating slash is considered the 'resourceName',
	// even if it contains colons,
	// like in 'arn:aws:cognito-sync:region:account:identitypool/us-east-1:1a1a1a1a-ffff-1111-9999-12345678:bla'.
	ArnFormat_SLASH_RESOURCE_NAME ArnFormat = "SLASH_RESOURCE_NAME"
	// This represents a format where the 'resource' and 'resourceName' parts are seperated with a slash, but there is also an additional slash after the colon separating 'account' from 'resource'.
	//
	// Like in: 'arn:aws:service:region:account:/resource/resourceName'.
	// Note that the leading slash is _not_ included in the parsed 'resource' part.
	ArnFormat_SLASH_RESOURCE_SLASH_RESOURCE_NAME ArnFormat = "SLASH_RESOURCE_SLASH_RESOURCE_NAME"
)

type Aspects ¶ 

type Aspects interface {
	// The list of aspects which were directly applied on this scope.

Example: 

import cdk "github.com/aws/aws-cdk-go/awscdk"
import "github.com/aws/constructs-go/constructs"

type myAspect struct {
}

func (this *myAspect) visit(node iConstruct) {

	}
}

func (this *myAspect) error(node iConstruct, message *string) {
	cdk.annotations.of(*node).addError(*message)
}

type myStack struct {
	stack
}

func newMyStack(scope construct, id *string) *myStack {
	this := &myStack{}
	cdk.NewStack_Override(this, scope, id)

	stack := cdk.NewStack()
	cdk.NewCfnResource(stack, jsii.String("Foo"), &cfnResourceProps{
		type: jsii.String("Foo::Bar"),
		properties: map[string]interface{}{
			"Fred": jsii.String("Thud"),
		},
	})
	cdk.aspects.of(stack).add(NewMyAspect())
	return this
}

func Aspects_Of ¶ 

func Aspects_Of(scope constructs.IConstruct) Aspects

Returns the `Aspects` object associated with a construct scope.

type AssetHashType ¶ 

type AssetHashType string

The type of asset hash.

NOTE: the hash is used in order to identify a specific revision of the asset, and used for optimizing and caching deployment activities related to this asset such as packaging, uploading to Amazon S3, etc. 

const (
	// Based on the content of the source path.
	//
	// When bundling, use `SOURCE` when the content of the bundling output is not
	// stable across repeated bundling operations.
	AssetHashType_SOURCE AssetHashType = "SOURCE"
	// Based on the content of the bundling output.
	//
	// Use `OUTPUT` when the source of the asset is a top level folder containing
	// code and/or dependencies that are not directly linked to the asset.
	AssetHashType_OUTPUT AssetHashType = "OUTPUT"
	// Use a custom hash.
	AssetHashType_CUSTOM AssetHashType = "CUSTOM"

	// file extension over, and set the prefix.
	DefaultAddFileAsset(stack Stack, asset *FileAssetSource, target *AssetManifestFileDestination) *cloudassemblyschema.FileDestination
	// Write the manifest to disk, and add it to the synthesis session.

type AssetOptions struct {
	// Specify a custom hash for this asset.
	//
	// If `assetHashType` is set it must
	// be set to `AssetHashType.CUSTOM`. For consistency, this custom hash will

	// NOTE: the hash is used in order to identify a specific revision of the asset, and
	// used for optimizing and caching deployment activities related to this asset such as
	// packaging, uploading to Amazon S3, etc. If you chose to customize the hash, you will

type AssetStaging ¶ 

type AssetStaging interface {

	// Absolute path to the asset data.
	//
	// If asset staging is disabled, this will just be the source path or
	// a temporary directory used for bundling.
	//
	// If asset staging is enabled it will be the staged path.
	//
	// IMPORTANT: If you are going to call `addFileAsset()`, use
	// `relativeStagedPath()` instead.
	AbsoluteStagedPath() *string
	// A cryptographic hash of the asset.
	AssetHash() *string
	// Whether this asset is an archive (zip or jar).
	IsArchive() *bool
	// The tree node.
	Node() constructs.Node
	// How this asset should be packaged.
	Packaging() FileAssetPackaging
	// The absolute path of the asset as it was referenced by the user.
	SourcePath() *string
	// Return the path to the staged asset, relative to the Cloud Assembly (manifest) directory of the given stack.
	//
	// Only returns a relative path if the asset was staged, returns an absolute path if
	// it was not staged.
	//
	// A bundled asset might end up in the outDir and still not count as
	// "staged"; if asset staging is disabled we're technically expected to
	// reference source directories, but we don't have a source directory for the
	// bundled outputs (as the bundle output is written to a temporary
	// directory). Nevertheless, we will still return an absolute path.
	//
	// A non-obvious directory layout may look like this:
	//
	// “`
	//    CLOUD ASSEMBLY ROOT
	//      +-- asset.12345abcdef/
	//      +-- assembly-Stage
	//            +-- MyStack.template.json
	//            +-- MyStack.assets.json <- will contain { "path": "../asset.12345abcdef" }
	// “`.
	RelativeStagedPath(stack Stack) *string
	// Returns a string representation of this construct.
	ToString() *string
}

Stages a file or directory from a location on the file system into a staging directory.

This is controlled by the context key 'aws:cdk:asset-staging' and enabled by the CLI by default in order to ensure that when the CDK app exists, all assets are available for deployment. Otherwise, if an app references assets in temporary locations, those will not be available when it exists (see https://github.com/aws/aws-cdk/issues/1716).

The `stagedPath` property is a stringified token that represents the location of the file or directory after staging. It will be resolved only during the "prepare" stage and may be either the original path or the staged path depending on the context setting.

The file/directory are staged based on their content hash (fingerprint). This means that only if content was changed, copy will happen.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import cdk "github.com/aws/aws-cdk-go/awscdk"

	// If the template is *NOT* uploaded as an asset first and the template turns
	// out to be >50KB, it will need to be uploaded to S3 anyway. At that point

	// call, which may not have the right permissions to write to S3.
	SynthesizeTemplate(session ISynthesisSession, lookupRoleArn *string) *FileAssetSource
}

Synthesizer that reuses bootstrap roles from a different region.

A special synthesizer that behaves similarly to `DefaultStackSynthesizer`, but doesn't require bootstrapping the environment it operates in. Instead, it will re-use the Roles that were created for a different region (which is possible because IAM is a global service).

However, it will not assume asset buckets or repositories have been created, and therefore does not support assets.

Used by the CodePipeline construct for the support stacks needed for cross-region replication S3 buckets. App builders do not need to use this synthesizer directly.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import cdk "github.com/aws/aws-cdk-go/awscdk"

bootstraplessSynthesizer := cdk.NewBootstraplessSynthesizer(&bootstraplessSynthesizerProps{

)

type CfnAutoScalingReplacingUpdate ¶ 

type CfnAutoScalingReplacingUpdate struct {
	WillReplace *bool `field:"optional" json:"willReplace" yaml:"willReplace"`
}

Specifies whether an Auto Scaling group and the instances it contains are replaced during an update.

During replacement, AWS CloudFormation retains the old group until it finishes creating the new one. If the update fails, AWS CloudFormation can roll back to the old Auto Scaling group and delete the new Auto Scaling group.

While AWS CloudFormation creates the new group, it doesn't detach or attach any instances. After successfully creating the new Auto Scaling group, AWS CloudFormation deletes the old Auto Scaling group during the cleanup process.

When you set the WillReplace parameter, remember to specify a matching CreationPolicy. If the minimum number of instances (specified by the MinSuccessfulInstancesPercent property) don't signal success within the Timeout period (specified in the CreationPolicy policy), the replacement update fails and AWS CloudFormation rolls back to the old Auto Scaling group.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import cdk "github.com/aws/aws-cdk-go/awscdk"

cfnAutoScalingReplacingUpdate := &cfnAutoScalingReplacingUpdate{
	willReplace: jsii.Boolean(false),
}

type CfnAutoScalingRollingUpdate ¶ 

type CfnAutoScalingRollingUpdate struct {
	// Specifies the maximum number of instances that AWS CloudFormation updates.
	MaxBatchSize *float64 `field:"optional" json:"maxBatchSize" yaml:"maxBatchSize"`
	// Specifies the minimum number of instances that must be in service within the Auto Scaling group while AWS CloudFormation updates old instances.
	MinInstancesInService *float64 `field:"optional" json:"minInstancesInService" yaml:"minInstancesInService"`
	// Specifies the percentage of instances in an Auto Scaling rolling update that must signal success for an update to succeed.
	//
	// You can specify a value from 0 to 100. AWS CloudFormation rounds to the nearest tenth of a percent. For example, if you
	// update five instances with a minimum successful percentage of 50, three instances must signal success.
	//
	// If an instance doesn't send a signal within the time specified in the PauseTime property, AWS CloudFormation assumes
	// that the instance wasn't updated.
	//
	// If you specify this property, you must also enable the WaitOnResourceSignals and PauseTime properties.
	MinSuccessfulInstancesPercent *float64 `field:"optional" json:"minSuccessfulInstancesPercent" yaml:"minSuccessfulInstancesPercent"`
	// The amount of time that AWS CloudFormation pauses after making a change to a batch of instances to give those instances time to start software applications.
	//
	// For example, you might need to specify PauseTime when scaling up the number of
	// instances in an Auto Scaling group.
	//
	// If you enable the WaitOnResourceSignals property, PauseTime is the amount of time that AWS CloudFormation should wait
	// for the Auto Scaling group to receive the required number of valid signals from added or replaced instances. If the
	// PauseTime is exceeded before the Auto Scaling group receives the required number of signals, the update fails. For best
	// results, specify a time period that gives your applications sufficient time to get started. If the update needs to be
	// rolled back, a short PauseTime can cause the rollback to fail.
	//
	// Specify PauseTime in the ISO8601 duration format (in the format PT#H#M#S, where each # is the number of hours, minutes,
	// and seconds, respectively). The maximum PauseTime is one hour (PT1H).
	PauseTime *string `field:"optional" json:"pauseTime" yaml:"pauseTime"`
	// Specifies the Auto Scaling processes to suspend during a stack update.
	//
	// Suspending processes prevents Auto Scaling from
	// interfering with a stack update. For example, you can suspend alarming so that Auto Scaling doesn't execute scaling
	// policies associated with an alarm. For valid values, see the ScalingProcesses.member.N parameter for the SuspendProcesses
	// action in the Auto Scaling API Reference.
	SuspendProcesses *[]*string `field:"optional" json:"suspendProcesses" yaml:"suspendProcesses"`
	// Specifies whether the Auto Scaling group waits on signals from new instances during an update.
	//
	// Use this property to
	// ensure that instances have completed installing and configuring applications before the Auto Scaling group update proceeds.
	// AWS CloudFormation suspends the update of an Auto Scaling group after new EC2 instances are launched into the group.
	// AWS CloudFormation must receive a signal from each new instance within the specified PauseTime before continuing the update.
	// To signal the Auto Scaling group, use the cfn-signal helper script or SignalResource API.
	//
	// To have instances wait for an Elastic Load Balancing health check before they signal success, add a health-check
	// verification by using the cfn-init helper script. For an example, see the verify_instance_health command in the Auto Scaling
	// rolling updates sample template.
	WaitOnResourceSignals *bool `field:"optional" json:"waitOnResourceSignals" yaml:"waitOnResourceSignals"`
}

To specify how AWS CloudFormation handles rolling updates for an Auto Scaling group, use the AutoScalingRollingUpdate policy.

Rolling updates enable you to specify whether AWS CloudFormation updates instances that are in an Auto Scaling group in batches or all at once.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import cdk "github.com/aws/aws-cdk-go/awscdk"

cfnAutoScalingRollingUpdate := &cfnAutoScalingRollingUpdate{
	maxBatchSize: jsii.Number(123),
	minInstancesInService: jsii.Number(123),
	minSuccessfulInstancesPercent: jsii.Number(123),
	pauseTime: jsii.String("pauseTime"),
	suspendProcesses: []*string{
		jsii.String("suspendProcesses"),
	},
	waitOnResourceSignals: jsii.Boolean(false),
}

type CfnAutoScalingScheduledAction ¶ 

type CfnAutoScalingScheduledAction struct {
	IgnoreUnmodifiedGroupSizeProperties *bool `field:"optional" json:"ignoreUnmodifiedGroupSizeProperties" yaml:"ignoreUnmodifiedGroupSizeProperties"`
}

With scheduled actions, the group size properties of an Auto Scaling group can change at any time.

When you update a stack with an Auto Scaling group and scheduled action, AWS CloudFormation always sets the group size property values of your Auto Scaling group to the values that are defined in the AWS::AutoScaling::AutoScalingGroup resource of your template, even if a scheduled action is in effect.

If you do not want AWS CloudFormation to change any of the group size property values when you have a scheduled action in effect, use the AutoScalingScheduledAction update policy to prevent AWS CloudFormation from changing the MinSize, MaxSize, or DesiredCapacity properties unless you have modified these values in your template.\

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import cdk "github.com/aws/aws-cdk-go/awscdk"

cfnAutoScalingScheduledAction := &cfnAutoScalingScheduledAction{
	ignoreUnmodifiedGroupSizeProperties: jsii.Boolean(false),
}

	// Capability to run CloudFormation macros.
	//
	// Pass this capability if your template includes macros, for example AWS::Include or AWS::Serverless.
	CfnCapabilities_AUTO_EXPAND CfnCapabilities = "AUTO_EXPAND"

To perform an AWS CodeDeploy deployment when the version changes on an AWS::Lambda::Alias resource, use the CodeDeployLambdaAliasUpdate update policy.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import cdk "github.com/aws/aws-cdk-go/awscdk"

cfnCodeDeployLambdaAliasUpdate := &cfnCodeDeployLambdaAliasUpdate{
	applicationName: jsii.String("applicationName"),
	deploymentGroupName: jsii.String("deploymentGroupName"),

	// the properties below are optional
	afterAllowTrafficHook: jsii.String("afterAllowTrafficHook"),
	beforeAllowTrafficHook: jsii.String("beforeAllowTrafficHook"),
}

type CfnCondition ¶ 

type CfnCondition interface {
	CfnElement
	ICfnConditionExpression
	IResolvable
	// Returns: the stack trace of the point where this Resource was created from, sourced
	// from the +metadata+ entry typed +aws:cdk:logicalId+, and with the bottom-most
	// node +internal+ entries filtered.
	CreationStack() *[]*string
	// The condition statement.
	Expression() ICfnConditionExpression
	SetExpression(val ICfnConditionExpression)
	// The logical ID for this CloudFormation stack element.
	//
	// The logical ID of the element
	// is calculated from the path of the resource node in the construct tree.
	//
	// To override this value, use `overrideLogicalId(newLogicalId)`.
	//
	// Returns: the logical ID as a stringified token. This value will only get
	// resolved during synthesis.
	LogicalId() *string
	// The tree node.
	Node() constructs.Node
	// The stack in which this element is defined.
	//
	// CfnElements must be defined within a stack scope (directly or indirectly).
	Stack() Stack
	// Overrides the auto-generated logical ID with a specific ID.
	OverrideLogicalId(newLogicalId *string)
	// Synthesizes the condition.
	Resolve(_context IResolveContext) interface{}
	// Returns a string representation of this construct.
	ToString() *string
}

Represents a CloudFormation condition, for resources which must be conditionally created and the determination must be made at deploy time.

Example: 

// Example automatically generated from non-compiling source. May contain errors.
rawBucket := s3.NewCfnBucket(this, jsii.String("Bucket"), &cfnBucketProps{
})
// -or-
rawBucketAlt := myBucket.node.defaultChild.(cfnBucket)

// then
rawBucket.cfnOptions.condition = awscdk.NewCfnCondition(this, jsii.String("EnableBucket"), &cfnConditionProps{
})
rawBucket.cfnOptions.metadata = map[string]interface{}{
	"metadataKey": jsii.String("MetadataValue"),
}

func NewCfnCondition ¶ 

func NewCfnCondition(scope constructs.Construct, id *string, props *CfnConditionProps) CfnCondition

Build a new condition.

The condition must be constructed with a condition token, that the condition is based on.

type CfnConditionProps ¶ 

type CfnConditionProps struct {
	// The expression that the condition will evaluate.
	Expression ICfnConditionExpression `field:"optional" json:"expression" yaml:"expression"`
}

Example: 

// Example automatically generated from non-compiling source. May contain errors.
rawBucket := s3.NewCfnBucket(this, jsii.String("Bucket"), &cfnBucketProps{
})
// -or-
rawBucketAlt := myBucket.node.defaultChild.(cfnBucket)

// then
rawBucket.cfnOptions.condition = awscdk.NewCfnCondition(this, jsii.String("EnableBucket"), &cfnConditionProps{
})
rawBucket.cfnOptions.metadata = map[string]interface{}{
	"metadataKey": jsii.String("MetadataValue"),
}

type CfnCreationPolicy ¶ 

type CfnCreationPolicy struct {
	// For an Auto Scaling group replacement update, specifies how many instances must signal success for the update to succeed.
	AutoScalingCreationPolicy *CfnResourceAutoScalingCreationPolicy `field:"optional" json:"autoScalingCreationPolicy" yaml:"autoScalingCreationPolicy"`
	// When AWS CloudFormation creates the associated resource, configures the number of required success signals and the length of time that AWS CloudFormation waits for those signals.
	ResourceSignal *CfnResourceSignal `field:"optional" json:"resourceSignal" yaml:"resourceSignal"`
}

Associate the CreationPolicy attribute with a resource to prevent its status from reaching create complete until AWS CloudFormation receives a specified number of success signals or the timeout period is exceeded.

To signal a resource, you can use the cfn-signal helper script or SignalResource API. AWS CloudFormation publishes valid signals to the stack events so that you track the number of signals sent.

The creation policy is invoked only when AWS CloudFormation creates the associated resource. Currently, the only AWS CloudFormation resources that support creation policies are AWS::AutoScaling::AutoScalingGroup, AWS::EC2::Instance, and AWS::CloudFormation::WaitCondition.

Use the CreationPolicy attribute when you want to wait on resource configuration actions before stack creation proceeds. For example, if you install and configure software applications on an EC2 instance, you might want those applications to be running before proceeding. In such cases, you can add a CreationPolicy attribute to the instance, and then send a success signal to the instance after the applications are installed and configured. For a detailed example, see Deploying Applications on Amazon EC2 with AWS CloudFormation.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import cdk "github.com/aws/aws-cdk-go/awscdk"

cfnCreationPolicy := &cfnCreationPolicy{
	autoScalingCreationPolicy: &cfnResourceAutoScalingCreationPolicy{
		minSuccessfulInstancesPercent: jsii.Number(123),

}

A CloudFormation `AWS::CloudFormation::CustomResource`.

In a CloudFormation template, you use the `AWS::CloudFormation::CustomResource` or `Custom:: *String*` resource type to specify custom resources.

Custom resources provide a way for you to write custom provisioning logic in CloudFormation template and have CloudFormation run it during a stack operation, such as when you create, update or delete a stack. For more information, see [Custom resources](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/template-custom-resources.html) .

> If you use the [VPC endpoints](https://docs.aws.amazon.com/vpc/latest/userguide/vpc-endpoints.html) feature, custom resources in the VPC must have access to CloudFormation -specific Amazon Simple Storage Service ( Amazon S3 ) buckets. Custom resources must send responses to a presigned Amazon S3 URL. If they can't send responses to Amazon S3 , CloudFormation won't receive a response and the stack operation fails. For more information, see [Setting up VPC endpoints for AWS CloudFormation](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-vpce-bucketnames.html) .

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import cdk "github.com/aws/aws-cdk-go/awscdk"

cfnCustomResource := cdk.NewCfnCustomResource(this, jsii.String("MyCfnCustomResource"), &cfnCustomResourceProps{

type CfnCustomResourceProps struct {
	// > Only one property is defined by AWS for a custom resource: `ServiceToken` .
	//
	// All other properties are defined by the service provider.
	//
	// The service token that was given to the template developer by the service provider to access the service, such as an Amazon SNS topic ARN or Lambda function ARN. The service token must be from the same Region in which you are creating the stack.

cfnCustomResourceProps := &cfnCustomResourceProps{
	serviceToken: jsii.String("serviceToken"),
}

type CfnDeletionPolicy ¶ 

type CfnDeletionPolicy string

With the DeletionPolicy attribute you can preserve or (in some cases) backup a resource when its stack is deleted.

You specify a DeletionPolicy attribute for each resource that you want to control. If a resource has no DeletionPolicy attribute, AWS CloudFormation deletes the resource by default. Note that this capability also applies to update operations that lead to resources being removed. 

const (
	// AWS CloudFormation deletes the resource and all its content if applicable during stack deletion.
	//
	// You can add this
	// deletion policy to any resource type. By default, if you don't specify a DeletionPolicy, AWS CloudFormation deletes
	// your resources. However, be aware of the following considerations:
	CfnDeletionPolicy_DELETE CfnDeletionPolicy = "DELETE"
	// AWS CloudFormation keeps the resource without deleting the resource or its contents when its stack is deleted.
	//
	// You can add this deletion policy to any resource type. Note that when AWS CloudFormation completes the stack deletion,
	// the stack will be in Delete_Complete state; however, resources that are retained continue to exist and continue to incur
	// applicable charges until you delete those resources.
	CfnDeletionPolicy_RETAIN CfnDeletionPolicy = "RETAIN"
	// For resources that support snapshots (AWS::EC2::Volume, AWS::ElastiCache::CacheCluster, AWS::ElastiCache::ReplicationGroup, AWS::RDS::DBInstance, AWS::RDS::DBCluster, and AWS::Redshift::Cluster), AWS CloudFormation creates a snapshot for the resource before deleting it.
	//
	// Note that when AWS CloudFormation completes the stack deletion, the stack will be in the
	// Delete_Complete state; however, the snapshots that are created with this policy continue to exist and continue to
	// incur applicable charges until you delete those snapshots.
	CfnDeletionPolicy_SNAPSHOT CfnDeletionPolicy = "SNAPSHOT"

type CfnJson ¶ 

type CfnJson interface {
	constructs.Construct
	IResolvable
	// The creation stack of this resolvable which will be appended to errors thrown during resolution.
	//
	// This may return an array with a single informational element indicating how
	// to get this property populated, if it was skipped for performance reasons.
	CreationStack() *[]*string
	// The tree node.
	Node() constructs.Node
	// An Fn::GetAtt to the JSON object passed through `value` and resolved during synthesis.
	//
	// Normally there is no need to use this property since `CfnJson` is an
	// IResolvable, so it can be simply used as a value.
	Value() Reference
	// Produce the Token's value at resolution time.
	Resolve(_arg IResolveContext) interface{}
	// This is required in case someone JSON.stringifys an object which refrences this object. Otherwise, we'll get a cyclic JSON reference.
	ToJSON() *string
	// Returns a string representation of this construct.
	ToString() *string
}

Captures a synthesis-time JSON object a CloudFormation reference which resolves during deployment to the resolved values of the JSON object.

The main use case for this is to overcome a limitation in CloudFormation that does not allow using intrinsic functions as dictionary keys (because dictionary keys in JSON must be strings). Specifically this is common in IAM conditions such as `StringEquals: { lhs: "rhs" }` where you want "lhs" to be a reference.

This object is resolvable, so it can be used as a value.

This construct is backed by a custom resource.

Example: 

// Example automatically generated from non-compiling source. May contain errors.
tagParam := awscdk.NewCfnParameter(this, jsii.String("TagName"))

stringEquals := awscdk.NewCfnJson(this, jsii.String("ConditionJson"), &cfnJsonProps{
	value: map[string]*bool{
		fmt.Sprintf("aws:PrincipalTag/%v", tagParam.valueAsString): jsii.Boolean(true),

}

A CloudFormation `AWS::CloudFormation::PublicTypeVersion`.

Tests and publishes a registered extension as a public, third-party extension.

CloudFormation first tests the extension to make sure it meets all necessary requirements for being published in the CloudFormation registry. If it does, CloudFormation then publishes it to the registry as a public third-party extension in this Region. Public extensions are available for use by all CloudFormation users.

- For resource types, testing includes passing all contracts tests defined for the type. - For modules, testing includes determining if the module's model meets all necessary requirements.

For more information, see [Testing your public extension prior to publishing](https://docs.aws.amazon.com/cloudformation-cli/latest/userguide/publish-extension.html#publish-extension-testing) in the *CloudFormation CLI User Guide* .

If you don't specify a version, CloudFormation uses the default version of the extension in your account and Region for testing.

To perform testing, CloudFormation assumes the execution role specified when the type was registered.

An extension must have a test status of `PASSED` before it can be published. For more information, see [Publishing extensions to make them available for public use](https://docs.aws.amazon.com/cloudformation-cli/latest/userguide/resource-type-publish.html) in the *CloudFormation CLI User Guide* .

A CloudFormation `AWS::CloudFormation::Publisher`.

Registers your account as a publisher of public extensions in the CloudFormation registry. Public extensions are available for use by all CloudFormation users.

For information on requirements for registering as a public extension publisher, see [Registering your account to publish CloudFormation extensions](https://docs.aws.amazon.com/cloudformation-cli/latest/userguide/publish-extension.html#publish-extension-prereqs) in the *CloudFormation CLI User Guide* .

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import cdk "github.com/aws/aws-cdk-go/awscdk"

cfnPublisher := cdk.NewCfnPublisher(this, jsii.String("MyCfnPublisher"), &cfnPublisherProps{
	acceptTermsAndConditions: jsii.Boolean(false),

	// the properties below are optional
	connectionArn: jsii.String("connectionArn"),
})

func NewCfnPublisher ¶ 

func NewCfnPublisher(scope constructs.Construct, id *string, props *CfnPublisherProps) CfnPublisher

Create a new `AWS::CloudFormation::Publisher`.

type CfnPublisherProps ¶ 

type CfnPublisherProps struct {
	// Whether you accept the [Terms and Conditions](https://docs.aws.amazon.com/https://cloudformation-registry-documents.s3.amazonaws.com/Terms_and_Conditions_for_AWS_CloudFormation_Registry_Publishers.pdf) for publishing extensions in the CloudFormation registry.

	AcceptTermsAndConditions interface{} `field:"required" json:"acceptTermsAndConditions" yaml:"acceptTermsAndConditions"`
	// If you are using a Bitbucket or GitHub account for identity verification, the Amazon Resource Name (ARN) for your connection to that account.
	//
	// For more information, see [Registering your account to publish CloudFormation extensions](https://docs.aws.amazon.com/cloudformation-cli/latest/userguide/publish-extension.html#publish-extension-prereqs) in the *CloudFormation CLI User Guide* .
	ConnectionArn *string `field:"optional" json:"connectionArn" yaml:"connectionArn"`
}

Properties for defining a `CfnPublisher`.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import cdk "github.com/aws/aws-cdk-go/awscdk"

cfnPublisherProps := &cfnPublisherProps{

	// the properties below are optional
	connectionArn: jsii.String("connectionArn"),
}

type CfnRefElement ¶ 

type CfnRefElement interface {
	CfnElement
	// Returns: the stack trace of the point where this Resource was created from, sourced
	// from the +metadata+ entry typed +aws:cdk:logicalId+, and with the bottom-most
	// node +internal+ entries filtered.
	CreationStack() *[]*string
	// The logical ID for this CloudFormation stack element.
	//
	// The logical ID of the element
	// is calculated from the path of the resource node in the construct tree.
	//
	// To override this value, use `overrideLogicalId(newLogicalId)`.
	//
	// Returns: the logical ID as a stringified token. This value will only get
	// resolved during synthesis.
	LogicalId() *string
	// The tree node.
	Node() constructs.Node
	// Return a string that will be resolved to a CloudFormation `{ Ref }` for this element.
	//
	// If, by any chance, the intrinsic reference of a resource is not a string, you could

	OverrideLogicalId(newLogicalId *string)
	// Returns a string representation of this construct.
	ToString() *string
}

Base class for referenceable CloudFormation constructs which are not Resources.

These constructs are things like Conditions and Parameters, can be referenced by taking the `.ref` attribute.

Resource constructs do not inherit from CfnRefElement because they have their own, more specific types returned from the .ref attribute. Also, some resources aren't referenceable at all (such as BucketPolicies or GatewayAttachments).

A CloudFormation `AWS::CloudFormation::ResourceVersion`.

Registers a resource version with the CloudFormation service. Registering a resource version makes it available for use in CloudFormation templates in your AWS account , and includes:

- Validating the resource schema. - Determining which handlers, if any, have been specified for the resource. - Making the resource available for use in your account.

For more information on how to develop resources and ready them for registration, see [Creating Resource Providers](https://docs.aws.amazon.com/cloudformation-cli/latest/userguide/resource-types.html) in the *CloudFormation CLI User Guide* .

You can have a maximum of 50 resource versions registered at a time. This maximum is per account and per Region.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import cdk "github.com/aws/aws-cdk-go/awscdk"

The Rules that define template constraints in an AWS Service Catalog portfolio describe when end users can use the template and which values they can specify for parameters that are declared in the AWS CloudFormation template used to create the product they are attempting to use.

Rules are useful for preventing end users from inadvertently specifying an incorrect value. For example, you can add a rule to verify whether end users specified a valid subnet in a given VPC or used m1.small instance types for test environments. AWS CloudFormation uses rules to validate parameter values before it creates the resources for the product.

A rule can include a RuleCondition property and must include an Assertions property. For each rule, you can define only one rule condition; you can define one or more asserts within the Assertions property. You define a rule condition and assertions by using rule-specific intrinsic functions.

Example: 

var cfnTemplate cfnInclude

// mutating the rule
var myParameter cfnParameter

rule := cfnTemplate.getRule(jsii.String("MyRule"))
rule.addAssertion(core.fn.conditionContains([]*string{
	jsii.String("m1.small"),
}, myParameter.valueAsString), jsii.String("MyParameter has to be m1.small"))

func NewCfnRule ¶ 

func NewCfnRule(scope constructs.Construct, id *string, props *CfnRuleProps) CfnRule

Creates and adds a rule.

type CfnRuleAssertion ¶ 

type CfnRuleAssertion struct {
	// The assertion.
	Assert ICfnConditionExpression `field:"required" json:"assert" yaml:"assert"`
	// The assertion description.
	AssertDescription *string `field:"required" json:"assertDescription" yaml:"assertDescription"`
}

A rule assertion.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import cdk "github.com/aws/aws-cdk-go/awscdk"

var cfnConditionExpression iCfnConditionExpression

cfnRuleAssertion := &cfnRuleAssertion{
	assert: cfnConditionExpression,
	assertDescription: jsii.String("assertDescription"),
}

type CfnRuleProps ¶ 

type CfnRuleProps struct {
	// Assertions which define the rule.
	Assertions *[]*CfnRuleAssertion `field:"optional" json:"assertions" yaml:"assertions"`
	// If the rule condition evaluates to false, the rule doesn't take effect.
	//
	// If the function in the rule condition evaluates to true, expressions in each assert are evaluated and applied.
	RuleCondition ICfnConditionExpression `field:"optional" json:"ruleCondition" yaml:"ruleCondition"`
}

A rule can include a RuleCondition property and must include an Assertions property.

For each rule, you can define only one rule condition; you can define one or more asserts within the Assertions property. You define a rule condition and assertions by using rule-specific intrinsic functions.

You can use the following rule-specific intrinsic functions to define rule conditions and assertions: 

Fn::And
Fn::Contains
Fn::EachMemberEquals
Fn::EachMemberIn
Fn::Equals
Fn::If
Fn::Not
Fn::Or
Fn::RefAll
Fn::ValueOf
Fn::ValueOfAll

A CloudFormation `AWS::CloudFormation::Stack`.

The `AWS::CloudFormation::Stack` resource nests a stack as a resource in a top-level template.

You can add output values from a nested stack within the containing template. You use the [GetAtt](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/intrinsic-function-reference-getatt.html) function with the nested stack's logical name and the name of the output value in the nested stack in the format `Outputs. *NestedStackOutputName*` .

> We strongly recommend that updates to nested stacks are run from the parent stack.

When you apply template changes to update a top-level stack, CloudFormation updates the top-level stack and initiates an update to its nested stacks. CloudFormation updates the resources of modified nested stacks, but doesn't update the resources of unmodified nested stacks. For more information, see [CloudFormation stack updates](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks.html) .

> You must acknowledge IAM capabilities for nested stacks that contain IAM resources. Also, verify that you have cancel update stack permissions, which is required if an update rolls back. For more information about IAM and CloudFormation , see [Controlling access with AWS Identity and Access Management](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-iam-template.html) .

Example: 

// The code below shows an example of how to instantiate this type.

A CloudFormation `AWS::CloudFormation::TypeActivation`.

Activates a public third-party extension, making it available for use in stack templates. For more information, see [Using public extensions](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/registry-public.html) in the *AWS CloudFormation User Guide* .

Once you have activated a public third-party extension in your account and region, use [SetTypeConfiguration](https://docs.aws.amazon.com/AWSCloudFormation/latest/APIReference/API_SetTypeConfiguration.html) to specify configuration properties for the extension. For more information, see [Configuring extensions at the account level](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/registry-register.html#registry-set-configuration) in the *CloudFormation User Guide* .

A CloudFormation `AWS::CloudFormation::WaitCondition`.

> For Amazon EC2 and Auto Scaling resources, we recommend that you use a `CreationPolicy` attribute instead of wait conditions. Add a CreationPolicy attribute to those resources, and use the cfn-signal helper script to signal when an instance creation process has completed successfully.

You can use a wait condition for situations like the following:

- To coordinate stack resource creation with configuration actions that are external to the stack creation. - To track the status of a configuration process.

For these situations, we recommend that you associate a [CreationPolicy](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-creationpolicy.html) attribute with the wait condition so that you don't have to use a wait condition handle. For more information and an example, see [Creating wait conditions in a template](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-waitcondition.html) . If you use a CreationPolicy with a wait condition, don't specify any of the wait condition's properties.

> If you use the [VPC endpoints](https://docs.aws.amazon.com/vpc/latest/userguide/vpc-endpoints.html) feature, resources in the VPC that respond to wait conditions must have access to CloudFormation , specific Amazon Simple Storage Service ( Amazon S3 ) buckets. Resources must send wait condition responses to a presigned Amazon S3 URL. If they can't send responses to Amazon S3 , CloudFormation won't receive a response and the stack operation fails. For more information, see [Setting up VPC endpoints for AWS CloudFormation](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-vpce-bucketnames.html) .

The `AWS::CloudFormation::WaitConditionHandle` type has no properties. When you reference the `WaitConditionHandle` resource by using the Ref function, AWS CloudFormation returns a presigned URL. You pass this URL to applications or scripts that are running on your Amazon EC2 instances to send signals to that URL. An associated `AWS::CloudFormation::WaitCondition` resource checks the URL for the required number of success signals or for a failure signal.

> Anytime you add a `WaitCondition` resource during a stack update or update a resource with a wait condition, you must associate the wait condition with a new `WaitConditionHandle` resource. Don't reuse an old wait condition handle that has already been defined in the template. If you reuse a wait condition handle, the wait condition might evaluate old signals from a previous create or update stack command. > Updates aren't supported for this resource.

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.

}

A synthesizer that uses conventional asset locations, but not conventional deployment roles.

Instead of assuming the bootstrapped deployment roles, all stack operations will be performed using the CLI's current credentials.

  • This synthesizer does not support deploying to accounts to which the CLI does not have credentials. It also does not support deploying using **CDK Pipelines**. For either of those features, use `DefaultStackSynthesizer`.
  • This synthesizer requires an S3 bucket and ECR repository with well-known names. To not depend on those, use `LegacyStackSynthesizer`.

Be aware that your CLI credentials must be valid for the duration of the entire deployment. If you are using session credentials, make sure the session lifetime is long enough.

By default, expects the environment to have been bootstrapped with just the staging resources of the Bootstrap Stack V2 (also known as "modern bootstrap stack"). You can override the default names using the synthesizer's construction properties.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import cdk "github.com/aws/aws-cdk-go/awscdk"

cliCredentialsStackSynthesizer := cdk.NewCliCredentialsStackSynthesizer(&cliCredentialsStackSynthesizerProps{

Instantiation of a custom resource, whose implementation is provided a Provider.

This class is intended to be used by construct library authors. Application builder should not be able to tell whether or not a construct is backed by a custom resource, and so the use of this class should be invisible.

Instead, construct library authors declare a custom construct that hides the choice of provider, and accepts a strongly-typed properties object with the properties your provider accepts.

Your custom resource provider (identified by the `serviceToken` property) can be one of 4 constructs:

  • If you are authoring a construct library or application, we recommend you use the `Provider` class in the `custom-resources` module.
  • If you are authoring a construct for the CDK's AWS Construct Library, you should use the `CustomResourceProvider` construct in this package.
  • If you want full control over the provider, you can always directly use a Lambda Function or SNS Topic by passing the ARN into `serviceToken`.

Example: 

// Example automatically generated from non-compiling source. May contain errors.
var myProvider customResourceProvider

awscdk.NewCustomResource(this, jsii.String("MyCustomResource"), &customResourceProps{
	serviceToken: myProvider.serviceToken,
	properties: map[string]interface{}{
		"myPropertyOne": jsii.String("one"),
		"myPropertyTwo": jsii.String("two"),
	},
})

An AWS-Lambda backed custom resource provider, for CDK Construct Library constructs.

This is a provider for `CustomResource` constructs, backed by an AWS Lambda Function. It only supports NodeJS runtimes.

> **Application builders do not need to use this provider type**. This is not > a generic custom resource provider class. It is specifically > intended to be used only by constructs in the AWS CDK Construct Library, and > only exists here because of reverse dependency issues (for example, it cannot > use `iam.PolicyStatement` objects, since the `iam` library already depends on > the CDK `core` library and we cannot have cyclic dependencies).

If you are not writing constructs for the AWS Construct Library, you should use the `Provider` class in the `custom-resources` module instead, which has a better API and supports all Lambda runtimes, not just Node.

N.B.: When you are writing Custom Resource Providers, there are a number of lifecycle events you have to pay attention to. These are documented in the README of the `custom-resources` module. Be sure to give the documentation in that module a read, regardless of whether you end up using the Provider class in there or this one.

Example: 

// Example automatically generated from non-compiling source. May contain errors.
provider := awscdk.CustomResourceProvider.getOrCreateProvider(this, jsii.String("Custom::MyCustomResourceType"), &customResourceProviderProps{
	codeDirectory: fmt.Sprintf("%v/my-handler", __dirname),
	runtime: awscdk.CustomResourceProviderRuntime_NODEJS_14_X,
})
provider.addToRolePolicy(map[string]*string{
	"Effect": jsii.String("Allow"),
	"Action": jsii.String("s3:GetObject"),
	"Resource": jsii.String("*"),
})

func CustomResourceProvider_GetOrCreateProvider(scope constructs.Construct, uniqueid *string, props *CustomResourceProviderProps) CustomResourceProvider

Returns a stack-level singleton for the custom resource provider.

Returns: the service token of the custom resource provider, which should be used when defining a `CustomResource`.

Uses conventionally named roles and asset storage locations.

This synthesizer:

  • Supports cross-account deployments (the CLI can have credentials to one account, and you can still deploy to another account by assuming roles with well-known names in the other account).
  • Supports the **CDK Pipelines** library.

Requires the environment to have been bootstrapped with Bootstrap Stack V2 (also known as "modern bootstrap stack"). The synthesizer adds a version check to the template, to make sure the bootstrap stack is recent enough to support all features expected by this synthesizer.

// Example automatically generated from non-compiling source. May contain errors.

}

Common interface for all assets.

type ICfnConditionExpression ¶ 

type ICfnConditionExpression interface {
	IResolvable
}

Represents a CloudFormation element that can be used within a Condition.

You can use intrinsic functions, such as “Fn.conditionIf“, “Fn.conditionEquals“, and “Fn.conditionNot“, to conditionally create stack resources. These conditions are evaluated based on input parameters that you declare when you create or update a stack. After you define all your conditions, you can associate them with resources or resource properties in the Resources and Outputs sections of a template.

You define all conditions in the Conditions section of a template except for “Fn.conditionIf“ conditions. You can use the “Fn.conditionIf“ condition in the metadata attribute, update policy attribute, and property values in the Resources section and Outputs sections of a template.

You might use conditions when you want to reuse a template that can create resources in different contexts, such as a test environment versus a production environment. In your template, you can add an EnvironmentType input parameter, which accepts either prod or test as inputs. For the production environment, you might include Amazon EC2 instances with certain capabilities; however, for the test environment, you want to use less capabilities to save costs. With conditions, you can define which resources are created and how they're configured for each environment type.

You can use `toString` when you wish to embed a condition expression in a property value that accepts a `string`. For example:

```ts 

new sqs.Queue(this, 'MyQueue', {
   queueName: Fn.conditionIf('Condition', 'Hello', 'World').toString()
});

```.

type ICfnResourceOptions ¶ 

type ICfnResourceOptions interface {

	// there is no need to use it in CDK projects.
	Condition() CfnCondition

	//
	// To signal a
	// resource, you can use the cfn-signal helper script or SignalResource API. AWS CloudFormation publishes valid signals
	// to the stack events so that you track the number of signals sent.
	CreationPolicy() *CfnCreationPolicy
	SetCreationPolicy(c *CfnCreationPolicy)
	// With the DeletionPolicy attribute you can preserve or (in some cases) backup a resource when its stack is deleted.
	//
	// You specify a DeletionPolicy attribute for each resource that you want to control. If a resource has no DeletionPolicy
	// attribute, AWS CloudFormation deletes the resource by default. Note that this capability also applies to update operations
	// that lead to resources being removed.
	DeletionPolicy() CfnDeletionPolicy
	SetDeletionPolicy(d CfnDeletionPolicy)
	// The description of this resource.
	//
	// Used for informational purposes only, is not processed in any way
	// (and stays with the CloudFormation template, is not passed to the underlying resource,
	// even if it does have a 'description' property).
	Description() *string
	SetDescription(d *string)
	// Metadata associated with the CloudFormation resource.
	//
	// This is not the same as the construct metadata which can be added
	// using construct.addMetadata(), but would not appear in the CloudFormation template automatically.
	Metadata() *map[string]interface{}
	SetMetadata(m *map[string]interface{})
	// Use the UpdatePolicy attribute to specify how AWS CloudFormation handles updates to the AWS::AutoScaling::AutoScalingGroup resource.
	//
	// AWS CloudFormation invokes one of three update policies depending on the type of change you make or whether a
	// scheduled action is associated with the Auto Scaling group.
	UpdatePolicy() *CfnUpdatePolicy
	SetUpdatePolicy(u *CfnUpdatePolicy)
	// Use the UpdateReplacePolicy attribute to retain or (in some cases) backup the existing physical instance of a resource when it is replaced during a stack update operation.
	UpdateReplacePolicy() CfnDeletionPolicy
	SetUpdateReplacePolicy(u CfnDeletionPolicy)
	// The version of this resource.
	//
	// Used only for custom CloudFormation resources.
	// See: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-cfn-customresource.html
	//

	// The synthesizer must rely on some out-of-band mechanism to make sure the given files

	// call, which may not have the right permissions to write to S3.
	SynthesizeTemplate(session ISynthesisSession, lookupRoleArn *string) *FileAssetSource
}

Use the CDK classic way of referencing assets.

This synthesizer will generate CloudFormation parameters for every referenced asset, and use the CLI's current credentials to deploy the stack.

  • It does not support cross-account deployment (the CLI must have credentials to the account you are trying to deploy to).
  • It cannot be used with **CDK Pipelines**. To deploy using CDK Pipelines, you must use the `DefaultStackSynthesizer`.
  • Each asset will take up a CloudFormation Parameter in your template. Keep in mind that there is a maximum of 200 parameters in a CloudFormation template. To use determinstic asset locations instead, use `CliCredentialsStackSynthesizer`.

Be aware that your CLI credentials must be valid for the duration of the entire deployment. If you are using session credentials, make sure the session lifetime is long enough.

This is the only StackSynthesizer that supports customizing asset behavior by overriding `Stack.addFileAsset()` and `Stack.addDockerImageAsset()`.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.

	//
	// See: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/transform-section-structure.html
	//
	AddTransform(transform *string)
	// Returns the naming scheme used to allocate logical IDs.
	//
	// By default, uses
	// the `HashedAddressingScheme` but this method can be overridden to customize
	// this behavior.
	//
	// In order to make sure logical IDs are unique and stable, we hash the resource
	// construct tree path (i.e. toplevel/secondlevel/.../myresource) and add it as
	// a suffix to the path components joined without a separator (CloudFormation
	// IDs only allow alphanumeric characters).
	//
	// The result will be:
	//
	//    <path.join(”)><md5(path.join('/')>
	//      "human"      "hash"
	//
	// If the "human" part of the ID exceeds 240 characters, we simply trim it so
	// the total ID doesn't exceed CloudFormation's 255 character limit.
	//
	// We only take 8 characters from the md5 hash (0.000005 chance of collision).
	//
	// Special cases:
	//
	// - If the path only contains a single component (i.e. it's a top-level
	//    resource), we won't add the hash to it. The hash is not needed for
	//    disamiguation and also, it allows for a more straightforward migration an
	//    existing CloudFormation template to a CDK stack without logical ID changes
	//    (or renames).
	// - For aesthetic reasons, if the last components of the path are the same
	//    (i.e. `L1/L2/Pipeline/Pipeline`), they will be de-duplicated to make the
	//    resulting human portion of the ID more pleasing: `L1L2Pipeline<HASH>`
	//    instead of `L1L2PipelinePipeline<HASH>`
	// - If a component is named "Default" it will be omitted from the path. This
	//    allows refactoring higher level abstractions around constructs without affecting
	//    the IDs of already deployed resources.
	// - If a component is named "Resource" it will be omitted from the user-visible
	//    path, but included in the hash. This reduces visual noise in the human readable
	//    part of the identifier.
	AllocateLogicalId(cfnElement CfnElement) *string
	// Create a CloudFormation Export for a string list value.
	//
	// Returns a string list representing the corresponding `Fn.importValue()`
	// expression for this Export. The export expression is automatically wrapped with an
	// `Fn::Join` and the import value with an `Fn::Split`, since CloudFormation can only
	// export strings. You can control the name for the export by passing the `name` option.
	//
	// If you don't supply a value for `name`, the value you're exporting must be
	// a Resource attribute (for example: `bucket.bucketName`) and it will be
	// given the same name as the automatic cross-stack reference that would be created
	// if you used the attribute in another Stack.
	//
	// One of the uses for this method is to *remove* the relationship between
	// two Stacks established by automatic cross-stack references. It will
	// temporarily ensure that the CloudFormation Export still exists while you
	// remove the reference from the consuming stack. After that, you can remove
	// the resource and the manual export.

	// the resource and the manual export.
	//
	// ## Example
	//
	// Here is how the process works. Let's say there are two stacks,
	// `producerStack` and `consumerStack`, and `producerStack` has a bucket
	// called `bucket`, which is referenced by `consumerStack` (perhaps because
	// an AWS Lambda Function writes into it, or something like that).
	//
	// It is not safe to remove `producerStack.bucket` because as the bucket is being
	// deleted, `consumerStack` might still be using it.
	//
	// Instead, the process takes two deployments:
	//
	// ### Deployment 1: break the relationship
	//
	// - Make sure `consumerStack` no longer references `bucket.bucketName` (maybe the consumer
	//    stack now uses its own bucket, or it writes to an AWS DynamoDB table, or maybe you just
	//    remove the Lambda Function altogether).
	// - In the `ProducerStack` class, call `this.exportValue(this.bucket.bucketName)`. This
	//    will make sure the CloudFormation Export continues to exist while the relationship
	//    between the two stacks is being broken.
	// - Deploy (this will effectively only change the `consumerStack`, but it's safe to deploy both).
	//
	// ### Deployment 2: remove the bucket resource
	//
	// - You are now free to remove the `bucket` resource from `producerStack`.
	// - Don't forget to remove the `exportValue()` call as well.
	// - Deploy again (this time only the `producerStack` will be changed -- the bucket will be deleted).
	ExportValue(exportedValue interface{}, options *ExportValueOptions) *string
	// Creates an ARN from components.
	//
	// If `partition`, `region` or `account` are not specified, the stack's
	// partition, region and account will be used.
	//
	// If any component is the empty string, an empty string will be inserted
	// into the generated ARN at the location that component corresponds to.
	//
	// The ARN will be formatted as follows:
	//
	//    arn:{partition}:{service}:{region}:{account}:{resource}{sep}{resource-name}
	//
	// The required ARN pieces that are omitted will be taken from the stack that
	// the 'scope' is attached to. If all ARN pieces are supplied, the supplied scope
	// can be 'undefined'.
	FormatArn(components *ArnComponents) *string
	// Allocates a stack-unique CloudFormation-compatible logical identity for a specific resource.
	//
	// This method is called when a `CfnElement` is created and used to render the

	// this stage.
	//
	// This method uses the protected method `allocateLogicalId` to render the

	// class and override this method.
	GetLogicalId(element CfnElement) *string
	// Look up a fact value for the given fact for the region of this stack.

	//
	// What regions will be included in the lookup map is controlled by the

A CloudFormation nested stack.

When you apply template changes to update a top-level stack, CloudFormation updates the top-level stack and initiates an update to its nested stacks. CloudFormation updates the resources of modified nested stacks, but does not update the resources of unmodified nested stacks.

Furthermore, this stack will not be treated as an independent deployment artifact (won't be listed in "cdk list" or deployable through "cdk deploy"), but rather only synthesized as a template and uploaded as an asset to S3.

Cross references of resource attributes between the parent stack and the nested stack will automatically be translated to stack parameters and outputs.

type PermissionsBoundary ¶ added in v2.54.0 

type PermissionsBoundary interface {
}

Apply a permissions boundary to all IAM Roles and Users within a specific scope.

A permissions boundary is typically applied at the `Stage` scope. This allows setting different permissions boundaries per Stage. For example, you may _not_ apply a boundary to the `Dev` stage which deploys to a personal dev account, but you _do_ apply the default boundary to the `Prod` stage.

It is possible to apply different permissions boundaries to different scopes within your app. In this case the most specifically applied one wins

Example: 

// Example automatically generated from non-compiling source. May contain errors.
// no permissions boundary for dev stage
// no permissions boundary for dev stage
awscdk.NewStage(app, jsii.String("DevStage"))

// default boundary for prod stage
prodStage := awscdk.NewStage(app, jsii.String("ProdStage"), &stageProps{
	permissionsBoundary: permissionsBoundary_FromName(jsii.String("prod-pb")),
})

// overriding the pb applied for this stack
// overriding the pb applied for this stack
awscdk.Newstack(prodStage, jsii.String("ProdStack1"), &stackProps{
	permissionsBoundary: *permissionsBoundary_*FromName(jsii.String("stack-pb")),
})

// will inherit the permissions boundary from the stage
// will inherit the permissions boundary from the stage
awscdk.Newstack(prodStage, jsii.String("ProdStack2"))

func PermissionsBoundary_FromArn ¶ added in v2.54.0 

func PermissionsBoundary_FromArn(arn *string) PermissionsBoundary

Apply a permissions boundary with the given ARN to all IAM Roles and Users created within a scope.

The arn can include placeholders for the partition, region, qualifier, and account These placeholders will be replaced with the actual values if available. This requires that the Stack has the environment specified, it does not work with environment agnostic stacks.

- '${AWS::Partition}' - '${AWS::Region}' - '${AWS::AccountId}' - '${Qualifier}'.

Example: 

// Example automatically generated from non-compiling source. May contain errors.
var app app

awscdk.NewStage(app, jsii.String("ProdStage"), &stageProps{
	permissionsBoundary: permissionsBoundary_FromArn(jsii.String("arn:aws:iam::${AWS::AccountId}:policy/my-custom-permissions-boundary")),
})

func PermissionsBoundary_FromName ¶ added in v2.54.0 

func PermissionsBoundary_FromName(name *string) PermissionsBoundary

Apply a permissions boundary with the given name to all IAM Roles and Users created within a scope.

The name can include placeholders for the partition, region, qualifier, and account These placeholders will be replaced with the actual values if available. This requires that the Stack has the environment specified, it does not work with environment agnostic stacks.

- '${AWS::Partition}' - '${AWS::Region}' - '${AWS::AccountId}' - '${Qualifier}'.

Example: 

// Example automatically generated from non-compiling source. May contain errors.
var app app

awscdk.NewStage(app, jsii.String("ProdStage"), &stageProps{
	permissionsBoundary: permissionsBoundary_FromName(jsii.String("my-custom-permissions-boundary")),
})

type PermissionsBoundaryBindOptions ¶ added in v2.54.0 

type PermissionsBoundaryBindOptions struct {
}

Options for binding a Permissions Boundary to a construct scope.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import cdk "github.com/aws/aws-cdk-go/awscdk"

permissionsBoundaryBindOptions := &permissionsBoundaryBindOptions{
}

type PhysicalName ¶ 

type PhysicalName interface {
}

Includes special markers for automatic generation of physical names.

type Reference ¶ 

type Reference interface {
	Intrinsic
	// The captured stack trace which represents the location in which this token was created.
	CreationStack() *[]*string
	DisplayName() *string
	Target() constructs.IConstruct
	// Type that the Intrinsic is expected to evaluate to.
	TypeHint() ResolutionTypeHint
	// Creates a throwable Error object that contains the token creation stack trace.
	NewError(message *string) interface{}
	// Produce the Token's value at resolution time.
	Resolve(_context IResolveContext) interface{}
	// Turn this Token into JSON.
	//
	// Called automatically when JSON.stringify() is called on a Token.
	ToJSON() interface{}
	// Convert an instance of this Token to a string.
	//
	// This method will be called implicitly by language runtimes if the object
	// is embedded into a string. We treat it the same as an explicit
	// stringification.
	ToString() *string
	// Convert an instance of this Token to a string list.
	//
	// This method will be called implicitly by language runtimes if the object
	// is embedded into a list. We treat it the same as an explicit
	// stringification.
	ToStringList() *[]*string
}

An intrinsic Token that represents a reference to a construct.

References are recorded.

type RemovalPolicy ¶ 

type RemovalPolicy string

Possible values for a resource's Removal Policy.

The removal policy controls what happens to the resource if it stops being managed by CloudFormation. This can happen in one of three situations:

  • The resource is removed from the template, so CloudFormation stops managing it;
  • A change to the resource is made that requires it to be replaced, so CloudFormation stops managing it;
  • The stack is deleted, so CloudFormation stops managing all resources in it.

The Removal Policy applies to all above cases.

Many stateful resources in the AWS Construct Library will accept a `removalPolicy` as a property, typically defaulting it to `RETAIN`.

If the AWS Construct Library resource does not accept a `removalPolicy` argument, you can always configure it by using the escape hatch mechanism, as shown in the following example:

```ts declare const bucket: s3.Bucket;

const cfnBucket = bucket.node.findChild('Resource') as CfnResource; cfnBucket.applyRemovalPolicy(RemovalPolicy.DESTROY); ```.

Example: 

import opensearch "github.com/aws/aws-cdk-go/awscdk"

var api graphqlApi

user := iam.NewUser(this, jsii.String("User"))
domain := opensearch.NewDomain(this, jsii.String("Domain"), &domainProps{

	// The default policy to apply in case the removal policy is not defined.
	Default RemovalPolicy `field:"optional" json:"default" yaml:"default"`
}

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import cdk "github.com/aws/aws-cdk-go/awscdk"

removalPolicyOptions := &removalPolicyOptions{
	applyToUpdateReplacePolicy: jsii.Boolean(false),
	default: cdk.removalPolicy_DESTROY,
}

type RemoveTag ¶

	Key() *string
	Props() *TagProps
	ApplyTag(resource ITaggable)
	// All aspects can visit an IConstruct.
	Visit(construct constructs.IConstruct)
}

The RemoveTag Aspect will handle removing tags from this node and children.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import cdk "github.com/aws/aws-cdk-go/awscdk"

removeTag := cdk.NewRemoveTag(jsii.String("key"), &tagProps{
	applyToLaunchedInstances: jsii.Boolean(false),
	excludeResourceTypes: []*string{
		jsii.String("excludeResourceTypes"),
	},
	includeResourceTypes: []*string{

	priority: jsii.Number(123),
})

func NewRemoveTag ¶ 

func NewRemoveTag(key *string, props *TagProps) RemoveTag

type ResolutionTypeHint ¶ added in v2.55.0 

type ResolutionTypeHint string

Type hints for resolved values. 

const (
	// This value is expected to resolve to a String.
	ResolutionTypeHint_STRING ResolutionTypeHint = "STRING"
	// This value is expected to resolve to a Number.
	ResolutionTypeHint_NUMBER ResolutionTypeHint = "NUMBER"
	// This value is expected to resolve to a String List.
	ResolutionTypeHint_STRING_LIST ResolutionTypeHint = "STRING_LIST"
)

type ResolveChangeContextOptions ¶ 

type ResolveChangeContextOptions struct {
	// Change the 'allowIntrinsicKeys' option.
	AllowIntrinsicKeys *bool `field:"optional" json:"allowIntrinsicKeys" yaml:"allowIntrinsicKeys"`
}

Options that can be changed while doing a recursive resolve.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import cdk "github.com/aws/aws-cdk-go/awscdk"

resolveChangeContextOptions := &resolveChangeContextOptions{
	allowIntrinsicKeys: jsii.Boolean(false),
}

type ResolveOptions ¶ 

type ResolveOptions struct {
	// The resolver to apply to any resolvable tokens found.
	Resolver ITokenResolver `field:"required" json:"resolver" yaml:"resolver"`

	// Whether to remove undefined elements from arrays and objects when resolving.
	RemoveEmpty *bool `field:"optional" json:"removeEmpty" yaml:"removeEmpty"`
}

Options to the resolve() operation.

NOT the same as the ResolveContext; ResolveContext is exposed to Token implementors and resolution hooks, whereas this struct is just to bundle a number of things that would otherwise be arguments to resolve() in a readable way.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import cdk "github.com/aws/aws-cdk-go/awscdk"
import constructs "github.com/aws/constructs-go/constructs"

type Resource ¶ 

type Resource interface {
	constructs.Construct
	IResource
	// The environment this resource belongs to.
	//
	// For resources that are created and managed by the CDK
	// (generally, those created by creating new class instances like Role, Bucket, etc.),
	// this is always the same as the environment of the stack they belong to;
	// however, for imported resources
	// (those obtained from static methods like fromRoleArn, fromBucketName, etc.),
	// that might be different than the stack they were imported into.
	Env() *ResourceEnvironment
	// The tree node.
	Node() constructs.Node
	// Returns a string-encoded token that resolves to the physical name that should be passed to the CloudFormation resource.
	//
	// This value will resolve to one of the following:
	// - a concrete value (e.g. `"my-awesome-bucket"`)
	// - `undefined`, when a name should be generated by CloudFormation
	// - a concrete name generated automatically during synthesis, in
	//    cross-environment scenarios.
	PhysicalName() *string
	// The stack in which this resource is defined.
	Stack() Stack
	// Apply the given removal policy to this resource.
	//
	// The Removal Policy controls what happens to this resource when it stops
	// being managed by CloudFormation, either because you've removed it from the
	// CDK application or because you've made a change that requires the resource
	// to be replaced.
	//
	// The resource can be deleted (`RemovalPolicy.DESTROY`), or left in your AWS
	// account for data recovery and cleanup later (`RemovalPolicy.RETAIN`).
	ApplyRemovalPolicy(policy RemovalPolicy)
	GeneratePhysicalName() *string
	// Returns an environment-sensitive token that should be used for the resource's "ARN" attribute (e.g. `bucket.bucketArn`).
	//
	// Normally, this token will resolve to `arnAttr`, but if the resource is
	// referenced across environments, `arnComponents` will be used to synthesize
	// a concrete ARN with the resource's physical name. Make sure to reference
	// `this.physicalName` in `arnComponents`.
	GetResourceArnAttribute(arnAttr *string, arnComponents *ArnComponents) *string
	// Returns an environment-sensitive token that should be used for the resource's "name" attribute (e.g. `bucket.bucketName`).
	//
	// Normally, this token will resolve to `nameAttr`, but if the resource is
	// referenced across environments, it will be resolved to `this.physicalName`,
	// which will be a concrete name.
	GetResourceNameAttribute(nameAttr *string) *string
	// Returns a string representation of this construct.
	ToString() *string
}

A construct which represents an AWS resource.

type ResourceEnvironment ¶ 

type ResourceEnvironment struct {
	// The AWS account ID that this resource belongs to.
	//
	// Since this can be a Token
	// (for example, when the account is CloudFormation's AWS::AccountId intrinsic),
	// make sure to use Token.compareStrings()
	// instead of just comparing the values for equality.
	Account *string `field:"required" json:"account" yaml:"account"`
	// The AWS region that this resource belongs to.
	//
	// Since this can be a Token
	// (for example, when the region is CloudFormation's AWS::Region intrinsic),
	// make sure to use Token.compareStrings()
	// instead of just comparing the values for equality.
	Region *string `field:"required" json:"region" yaml:"region"`
}

Represents the environment a given resource lives in.

Used as the return value for the {@link IResource.env} property.

}

type ResourceProps ¶ 

type ResourceProps struct {
	// The AWS account ID this resource belongs to.
	Account *string `field:"optional" json:"account" yaml:"account"`
	// ARN to deduce region and account from.
	//
	// The ARN is parsed and the account and region are taken from the ARN.
	// This should be used for imported resources.
	//
	// Cannot be supplied together with either `account` or `region`.
	EnvironmentFromArn *string `field:"optional" json:"environmentFromArn" yaml:"environmentFromArn"`
	// The value passed in by users to the physical name prop of the resource.
	//
	// - `undefined` implies that a physical name will be allocated by
	//    CloudFormation during deployment.
	// - a concrete value implies a specific physical name
	// - `PhysicalName.GENERATE_IF_NEEDED` is a marker that indicates that a physical will only be generated
	//    by the CDK if it is needed for cross-environment references. Otherwise, it will be allocated by CloudFormation.
	PhysicalName *string `field:"optional" json:"physicalName" yaml:"physicalName"`
	// The AWS region this resource belongs to.
	Region *string `field:"optional" json:"region" yaml:"region"`

reverseOptions := &reverseOptions{
	failConcat: jsii.Boolean(false),
}

type RoleOptions ¶ added in v2.45.0 

type RoleOptions struct {

	AssumeRoleArn *string `field:"required" json:"assumeRoleArn" yaml:"assumeRoleArn"`
	// External ID to use when assuming the role.
	AssumeRoleExternalId *string `field:"optional" json:"assumeRoleExternalId" yaml:"assumeRoleExternalId"`
}

Options for specifying a role.

Example:

import cdk "github.com/aws/aws-cdk-go/awscdk"

roleOptions := &roleOptions{
	assumeRoleArn: jsii.String("assumeRoleArn"),

	// the properties below are optional

	Partition() *string
	Region() *string
	StackId() *string
	StackName() *string
	UrlSuffix() *string

import cdk "github.com/aws/aws-cdk-go/awscdk"

scopedAws := cdk.NewScopedAws(this)

func NewScopedAws ¶ 

func NewScopedAws(scope constructs.Construct) ScopedAws

type SecretValue ¶ 

type SecretValue interface {
	Intrinsic
	// The captured stack trace which represents the location in which this token was created.
	CreationStack() *[]*string
	// Type that the Intrinsic is expected to evaluate to.
	TypeHint() ResolutionTypeHint
	// Creates a throwable Error object that contains the token creation stack trace.
	NewError(message *string) interface{}
	// Resolve the secret.
	//
	// If the feature flag is not set, resolve as normal. Otherwise, throw a descriptive
	// error that the usage guard is missing.
	Resolve(context IResolveContext) interface{}
	// Turn this Token into JSON.
	//
	// Called automatically when JSON.stringify() is called on a Token.
	ToJSON() interface{}
	// Convert an instance of this Token to a string.
	//
	// This method will be called implicitly by language runtimes if the object
	// is embedded into a string. We treat it the same as an explicit
	// stringification.
	ToString() *string
	// Convert an instance of this Token to a string list.
	//
	// This method will be called implicitly by language runtimes if the object
	// is embedded into a list. We treat it the same as an explicit
	// stringification.
	ToStringList() *[]*string
	// Disable usage protection on this secret.
	//
	// Call this to indicate that you want to use the secret value held by this
	// object in an unchecked way. If you don't call this method, using the secret
	// value directly in a string context or as a property value somewhere will
	// produce an error.
	//
	// This method has 'unsafe' in the name on purpose! Make sure that the
	// construct property you are using the returned value in is does not end up
	// in a place in your AWS infrastructure where it could be read by anyone
	// unexpected.
	//
	// When in doubt, don't call this method and only pass the object to constructs that
	// accept `SecretValue` parameters.
	UnsafeUnwrap() *string
}

Work with secret values in the CDK.

Constructs that need secrets will declare parameters of type `SecretValue`.

The actual values of these secrets should not be committed to your repository, or even end up in the synthesized CloudFormation template. Instead, you should store them in an external system like AWS Secrets Manager or SSM Parameter Store, and you can reference them by calling `SecretValue.secretsManager()` or `SecretValue.ssmSecure()`.

You can use `SecretValue.unsafePlainText()` to construct a `SecretValue` from a literal string, but doing so is highly discouraged.

To make sure secret values don't accidentally end up in readable parts of your infrastructure definition (such as the environment variables of an AWS Lambda Function, where everyone who can read the function definition has access to the secret), using secret values directly is not allowed. You must pass them to constructs that accept `SecretValue` properties, which are guaranteed to use the value only in CloudFormation properties that are write-only.

If you are sure that what you are doing is safe, you can call `secretValue.unsafeUnwrap()` to access the protected string of the secret value.

(If you are writing something like an AWS Lambda Function and need to access a secret inside it, make the API call to `GetSecretValue` directly inside your Lamba's code, instead of using environment variables.)

Example: 

amplifyApp := amplify.NewApp(this, jsii.String("MyApp"), &appProps{
	sourceCodeProvider: amplify.NewGitHubSourceCodeProvider(&gitHubSourceCodeProviderProps{
		owner: jsii.String("<user>"),
		repository: jsii.String("<repo>"),
		oauthToken: awscdk.SecretValue.secretsManager(jsii.String("my-github-token")),
	}),
	basicAuth: amplify.basicAuth.fromCredentials(jsii.String("username"), awscdk.SecretValue.secretsManager(jsii.String("my-github-token"))),
})

func NewSecretValue ¶ 

func NewSecretValue(protectedValue interface{}, options *IntrinsicProps) SecretValue

Construct a SecretValue (do not use!).

Do not use the constructor directly: use one of the factory functions on the class instead.

func SecretValue_CfnDynamicReference ¶ 

func SecretValue_CfnDynamicReference(ref CfnDynamicReference) SecretValue

Obtain the secret value through a CloudFormation dynamic reference.

If possible, use `SecretValue.ssmSecure` or `SecretValue.secretsManager` directly.

func SecretValue_CfnParameter ¶ 

func SecretValue_CfnParameter(param CfnParameter) SecretValue

Obtain the secret value through a CloudFormation parameter.

Generally, this is not a recommended approach. AWS Secrets Manager is the recommended way to reference secrets.

func SecretValue_PlainText ¶ 

func SecretValue_PlainText(secret *string) SecretValue

Construct a literal secret value for use with secret-aware constructs.

Do not use this method for any secrets that you care about! The value will be visible to anyone who has access to the CloudFormation template (via the AWS Console, SDKs, or CLI).

The only reasonable use case for using this method is when you are testing. Deprecated: Use `unsafePlainText()` instead.

func SecretValue_ResourceAttribute ¶ added in v2.21.0 

func SecretValue_ResourceAttribute(attr *string) SecretValue

Use a resource's output as secret value.

func SecretValue_SecretsManager ¶ 

func SecretValue_SecretsManager(secretId *string, options *SecretsManagerSecretOptions) SecretValue

Creates a `SecretValue` with a value which is dynamically loaded from AWS Secrets Manager.

If you rotate the value in the Secret, you must also change at least one property on the resource where you are using the secret, to force CloudFormation to re-read the secret.

func SecretValue_SsmSecure ¶ 

func SecretValue_SsmSecure(parameterName *string, version *string) SecretValue

Use a secret value stored from a Systems Manager (SSM) parameter.

This secret source in only supported in a limited set of resources and properties. [Click here for the list of supported properties](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/dynamic-references.html#template-parameters-dynamic-patterns-resources).

func SecretValue_UnsafePlainText ¶ added in v2.21.0 

func SecretValue_UnsafePlainText(secret *string) SecretValue

Construct a literal secret value for use with secret-aware constructs.

Do not use this method for any secrets that you care about! The value will be visible to anyone who has access to the CloudFormation template (via the AWS Console, SDKs, or CLI).

The primary use case for using this method is when you are testing.

The other use case where this is appropriate is when constructing a JSON secret. For example, a JSON secret might have multiple fields where only some are actual secret values.

Example: 

// Example automatically generated from non-compiling source. May contain errors.
var secret secretValue

jsonSecret := map[string]secretValue{
	"username": awscdk.SecretValue.unsafePlainText(jsii.String("myUsername")),
	"password": secret,
}

type SecretsManagerSecretOptions ¶ 

type SecretsManagerSecretOptions struct {
	// The key of a JSON field to retrieve.
	//
	// This can only be used if the secret
	// stores a JSON object.
	JsonField *string `field:"optional" json:"jsonField" yaml:"jsonField"`
	// Specifies the unique identifier of the version of the secret you want to use.
	//
	// Can specify at most one of `versionId` and `versionStage`.
	VersionId *string `field:"optional" json:"versionId" yaml:"versionId"`
	// Specifies the secret version that you want to retrieve by the staging label attached to the version.
	//
	// Can specify at most one of `versionId` and `versionStage`.
	VersionStage *string `field:"optional" json:"versionStage" yaml:"versionStage"`
}

Options for referencing a secret value from Secrets Manager.

Example: 

codebuild.NewBitBucketSourceCredentials(this, jsii.String("CodeBuildBitBucketCreds"), &bitBucketSourceCredentialsProps{
	username: awscdk.SecretValue.secretsManager(jsii.String("my-bitbucket-creds"), &secretsManagerSecretOptions{
		jsonField: jsii.String("username"),
	}),
	password: awscdk.SecretValue.secretsManager(jsii.String("my-bitbucket-creds"), &secretsManagerSecretOptions{
		jsonField: jsii.String("password"),
	}),
})

type Size ¶ 

type Size interface {
	// Checks if size is a token or a resolvable object.
	IsUnresolved() *bool
	// Return this storage as a total number of gibibytes.
	//
	// Returns: the quantity of bytes expressed in gibibytes.
	ToGibibytes(opts *SizeConversionOptions) *float64
	// Return this storage as a total number of kibibytes.
	//
	// Returns: the quantity of bytes expressed in kibibytes.
	ToKibibytes(opts *SizeConversionOptions) *float64
	// Return this storage as a total number of mebibytes.
	//
	// Returns: the quantity of bytes expressed in mebibytes.
	ToMebibytes(opts *SizeConversionOptions) *float64
	// Return this storage as a total number of pebibytes.
	//
	// Returns: the quantity of bytes expressed in pebibytes.
	ToPebibytes(opts *SizeConversionOptions) *float64
	// Return this storage as a total number of tebibytes.
	//
	// Returns: the quantity of bytes expressed in tebibytes.
	ToTebibytes(opts *SizeConversionOptions) *float64
}

Represents the amount of digital storage.

The amount can be specified either as a literal value (e.g: `10`) which cannot be negative, or as an unresolved number token.

When the amount is passed as a token, unit conversion is not possible.

Example: 

var bucket bucket
// Provide a Lambda function that will transform records before delivery, with custom
// buffering and retry configuration
lambdaFunction := lambda.NewFunction(this, jsii.String("Processor"), &functionProps{
	runtime: lambda.runtime_NODEJS_14_X(),
	handler: jsii.String("index.handler"),
	code: lambda.code.fromAsset(path.join(__dirname, jsii.String("process-records"))),
})
lambdaProcessor := firehose.NewLambdaFunctionProcessor(lambdaFunction, &dataProcessorProps{
	bufferInterval: awscdk.Duration.minutes(jsii.Number(5)),
	bufferSize: awscdk.Size.mebibytes(jsii.Number(5)),
	retries: jsii.Number(5),
})
s3Destination := destinations.NewS3Bucket(bucket, &s3BucketProps{
	processor: lambdaProcessor,
})
firehose.NewDeliveryStream(this, jsii.String("Delivery Stream"), &deliveryStreamProps{
	destinations: []iDestination{
		s3Destination,
	},
})

type SizeConversionOptions ¶ 

type SizeConversionOptions struct {
	// How conversions should behave when it encounters a non-integer result.
	Rounding SizeRoundingBehavior `field:"optional" json:"rounding" yaml:"rounding"`
}

Options for how to convert time to a different unit.

Example: 

// Example automatically generated from non-compiling source. May contain errors.

	// If the result is not an integer, round it to the closest integer less than the result.
	SizeRoundingBehavior_FLOOR SizeRoundingBehavior = "FLOOR"
	// Don't round.
	//
	// Return even if the result is a fraction.
	SizeRoundingBehavior_NONE SizeRoundingBehavior = "NONE"
)

type Stack ¶ 

type Stack interface {
	constructs.Construct
	ITaggable
	// The AWS account into which this stack will be deployed.
	//
	// This value is resolved according to the following rules:
	//
	// 1. The value provided to `env.account` when the stack is defined. This can
	//     either be a concrete account (e.g. `585695031111`) or the
	//     `Aws.ACCOUNT_ID` token.
	// 3. `Aws.ACCOUNT_ID`, which represents the CloudFormation intrinsic reference
	//     `{ "Ref": "AWS::AccountId" }` encoded as a string token.
	//
	// Preferably, you should use the return value as an opaque string and not
	// attempt to parse it to implement your logic. If you do, you must first
	// check that it is a concerete value an not an unresolved token. If this
	// value is an unresolved token (`Token.isUnresolved(stack.account)` returns
	// `true`), this implies that the user wishes that this stack will synthesize
	// into a **account-agnostic template**. In this case, your code should either
	// fail (throw an error, emit a synth error using `Annotations.of(construct).addError()`) or
	// implement some other region-agnostic behavior.
	Account() *string
	// The ID of the cloud assembly artifact for this stack.
	ArtifactId() *string
	// Returns the list of AZs that are available in the AWS environment (account/region) associated with this stack.
	//
	// If the stack is environment-agnostic (either account and/or region are
	// tokens), this property will return an array with 2 tokens that will resolve
	// at deploy-time to the first two availability zones returned from CloudFormation's
	// `Fn::GetAZs` intrinsic function.
	//
	// If they are not available in the context, returns a set of dummy values and
	// reports them as missing, and let the CLI resolve them by calling EC2
	// `DescribeAvailabilityZones` on the target environment.
	//
	// To specify a different strategy for selecting availability zones override this method.
	AvailabilityZones() *[]*string
	// Indicates whether the stack requires bundling or not.
	BundlingRequired() *bool
	// Return the stacks this stack depends on.
	Dependencies() *[]Stack
	// The environment coordinates in which this stack is deployed.
	//
	// In the form
	// `aws://account/region`. Use `stack.account` and `stack.region` to obtain
	// the specific values, no need to parse.
	//
	// You can use this value to determine if two stacks are targeting the same
	// environment.
	//
	// If either `stack.account` or `stack.region` are not concrete values (e.g.
	// `Aws.ACCOUNT_ID` or `Aws.REGION`) the special strings `unknown-account` and/or
	// `unknown-region` will be used respectively to indicate this stack is
	// region/account-agnostic.
	Environment() *string
	// Indicates if this is a nested stack, in which case `parentStack` will include a reference to it's parent.
	Nested() *bool
	// If this is a nested stack, returns it's parent stack.
	NestedStackParent() Stack
	// If this is a nested stack, this represents its `AWS::CloudFormation::Stack` resource.
	//
	// `undefined` for top-level (non-nested) stacks.
	NestedStackResource() CfnResource
	// The tree node.
	Node() constructs.Node
	// Returns the list of notification Amazon Resource Names (ARNs) for the current stack.
	NotificationArns() *[]*string
	// The partition in which this stack is defined.
	Partition() *string
	// The AWS region into which this stack will be deployed (e.g. `us-west-2`).
	//
	// This value is resolved according to the following rules:
	//
	// 1. The value provided to `env.region` when the stack is defined. This can
	//     either be a concerete region (e.g. `us-west-2`) or the `Aws.REGION`
	//     token.

	//
	// This is either the name defined explicitly in the `stackName` prop or

	//
	AddTransform(transform *string)
	// Returns the naming scheme used to allocate logical IDs.
	//
	// By default, uses
	// the `HashedAddressingScheme` but this method can be overridden to customize
	// this behavior.
	//
	// In order to make sure logical IDs are unique and stable, we hash the resource
	// construct tree path (i.e. toplevel/secondlevel/.../myresource) and add it as
	// a suffix to the path components joined without a separator (CloudFormation
	// IDs only allow alphanumeric characters).
	//
	// The result will be:
	//
	//    <path.join(”)><md5(path.join('/')>
	//      "human"      "hash"
	//
	// If the "human" part of the ID exceeds 240 characters, we simply trim it so
	// the total ID doesn't exceed CloudFormation's 255 character limit.
	//
	// We only take 8 characters from the md5 hash (0.000005 chance of collision).
	//
	// Special cases:
	//
	// - If the path only contains a single component (i.e. it's a top-level
	//    resource), we won't add the hash to it. The hash is not needed for
	//    disamiguation and also, it allows for a more straightforward migration an
	//    existing CloudFormation template to a CDK stack without logical ID changes
	//    (or renames).
	// - For aesthetic reasons, if the last components of the path are the same
	//    (i.e. `L1/L2/Pipeline/Pipeline`), they will be de-duplicated to make the
	//    resulting human portion of the ID more pleasing: `L1L2Pipeline<HASH>`
	//    instead of `L1L2PipelinePipeline<HASH>`
	// - If a component is named "Default" it will be omitted from the path. This
	//    allows refactoring higher level abstractions around constructs without affecting
	//    the IDs of already deployed resources.
	// - If a component is named "Resource" it will be omitted from the user-visible
	//    path, but included in the hash. This reduces visual noise in the human readable
	//    part of the identifier.
	AllocateLogicalId(cfnElement CfnElement) *string
	// Create a CloudFormation Export for a string list value.
	//
	// Returns a string list representing the corresponding `Fn.importValue()`
	// expression for this Export. The export expression is automatically wrapped with an
	// `Fn::Join` and the import value with an `Fn::Split`, since CloudFormation can only
	// export strings. You can control the name for the export by passing the `name` option.
	//
	// If you don't supply a value for `name`, the value you're exporting must be
	// a Resource attribute (for example: `bucket.bucketName`) and it will be
	// given the same name as the automatic cross-stack reference that would be created
	// if you used the attribute in another Stack.
	//
	// One of the uses for this method is to *remove* the relationship between
	// two Stacks established by automatic cross-stack references. It will
	// temporarily ensure that the CloudFormation Export still exists while you
	// remove the reference from the consuming stack. After that, you can remove
	// the resource and the manual export.

	// remove the reference from the consuming stack. After that, you can remove
	// the resource and the manual export.
	//
	// ## Example
	//
	// Here is how the process works. Let's say there are two stacks,
	// `producerStack` and `consumerStack`, and `producerStack` has a bucket
	// called `bucket`, which is referenced by `consumerStack` (perhaps because
	// an AWS Lambda Function writes into it, or something like that).
	//
	// It is not safe to remove `producerStack.bucket` because as the bucket is being
	// deleted, `consumerStack` might still be using it.
	//
	// Instead, the process takes two deployments:
	//
	// ### Deployment 1: break the relationship
	//
	// - Make sure `consumerStack` no longer references `bucket.bucketName` (maybe the consumer
	//    stack now uses its own bucket, or it writes to an AWS DynamoDB table, or maybe you just
	//    remove the Lambda Function altogether).
	// - In the `ProducerStack` class, call `this.exportValue(this.bucket.bucketName)`. This
	//    will make sure the CloudFormation Export continues to exist while the relationship
	//    between the two stacks is being broken.
	// - Deploy (this will effectively only change the `consumerStack`, but it's safe to deploy both).
	//
	// ### Deployment 2: remove the bucket resource
	//
	// - You are now free to remove the `bucket` resource from `producerStack`.
	// - Don't forget to remove the `exportValue()` call as well.
	// - Deploy again (this time only the `producerStack` will be changed -- the bucket will be deleted).
	ExportValue(exportedValue interface{}, options *ExportValueOptions) *string
	// Creates an ARN from components.
	//
	// If `partition`, `region` or `account` are not specified, the stack's
	// partition, region and account will be used.
	//
	// If any component is the empty string, an empty string will be inserted
	// into the generated ARN at the location that component corresponds to.
	//
	// The ARN will be formatted as follows:
	//
	//    arn:{partition}:{service}:{region}:{account}:{resource}{sep}{resource-name}
	//
	// The required ARN pieces that are omitted will be taken from the stack that
	// the 'scope' is attached to. If all ARN pieces are supplied, the supplied scope
	// can be 'undefined'.
	FormatArn(components *ArnComponents) *string
	// Allocates a stack-unique CloudFormation-compatible logical identity for a specific resource.
	//
	// This method is called when a `CfnElement` is created and used to render the
	// initial logical identity of resources. Logical ID renames are applied at
	// this stage.
	//
	// This method uses the protected method `allocateLogicalId` to render the
	// logical ID for an element. To modify the naming scheme, extend the `Stack`
	// class and override this method.
	GetLogicalId(element CfnElement) *string
	// Look up a fact value for the given fact for the region of this stack.
	//
	// Will return a definite value only if the region of the current stack is resolved.

	//
	// What regions will be included in the lookup map is controlled by the
	// `@aws-cdk/core:target-partitions` context value: it must be set to a list
	// of partitions, and only regions from the given partitions will be included.
	// If no such context key is set, all regions will be included.
	//
	// This function is intended to be used by construct library authors. Application
	// builders can rely on the abstractions offered by construct libraries and do
	// not have to worry about regional facts.
	//
	// If `defaultValue` is not given, it is an error if the fact is unknown for
	// the given region.
	RegionalFact(factName *string, defaultValue *string) *string
	// Rename a generated logical identities.
	//

}

An abstract application modeling unit consisting of Stacks that should be deployed together.

Derive a subclass of `Stage` and use it to model a single instance of your application.

You can then instantiate your subclass multiple times to model multiple copies of your application which should be be deployed to different environments.

Example: 

var pipeline codePipeline

preprod := NewMyApplicationStage(this, jsii.String("PreProd"))
prod := NewMyApplicationStage(this, jsii.String("Prod"))

pipeline.addStage(preprod, &addStageOpts{
	post: []step{
		pipelines.NewShellStep(jsii.String("Validate Endpoint"), &shellStepProps{
			commands: []*string{
				jsii.String("curl -Ssf https://my.webservice.com/"),
			},
		}),
	},
})
pipeline.addStage(prod, &addStageOpts{
	pre: []*step{
		pipelines.NewManualApprovalStep(jsii.String("PromoteToProd")),
	},
})

	},
	assumeRoleArn: jsii.String("assumeRoleArn"),
	assumeRoleExternalId: jsii.String("assumeRoleExternalId"),
	bootstrapStackVersionSsmParameter: jsii.String("bootstrapStackVersionSsmParameter"),
	cloudFormationExecutionRoleArn: jsii.String("cloudFormationExecutionRoleArn"),
	lookupRole: &bootstrapRole{
		arn: jsii.String("arn"),

		// the properties below are optional
		assumeRoleExternalId: jsii.String("assumeRoleExternalId"),
		bootstrapStackVersionSsmParameter: jsii.String("bootstrapStackVersionSsmParameter"),
		requiresBootstrapStackVersion: jsii.Number(123),
	},
	parameters: map[string]*string{
		"parametersKey": jsii.String("parameters"),
	},
	requiresBootstrapStackVersion: jsii.Number(123),

}

type Tag ¶ 

type Tag interface {
	IAspect
	// The string key for the tag.

	Props() *TagProps
	// The string value of the tag.
	Value() *string
	ApplyTag(resource ITaggable)
	// All aspects can visit an IConstruct.
	Visit(construct constructs.IConstruct)
}

The Tag Aspect will handle adding a tag to this node and cascading tags to children.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import cdk "github.com/aws/aws-cdk-go/awscdk"

tag := cdk.NewTag(jsii.String("key"), jsii.String("value"), &tagProps{
	applyToLaunchedInstances: jsii.Boolean(false),
	excludeResourceTypes: []*string{
		jsii.String("excludeResourceTypes"),
	},

	},
	priority: jsii.Number(123),
})

func NewTag ¶

type TagManager ¶ 

type TagManager interface {
	// A lazy value that represents the rendered tags at synthesis time.
	//
	// If you need to make a custom construct taggable, use the value of this
	// property to pass to the `tags` property of the underlying construct.
	RenderedTags() IResolvable
	// The property name for tag values.
	//
	// Normally this is `tags` but some resources choose a different name. Cognito
	// UserPool uses UserPoolTags.
	TagPropertyName() *string
	// Determine if the aspect applies here.
	//
	// Looks at the include and exclude resourceTypeName arrays to determine if
	// the aspect applies here.
	ApplyTagAspectHere(include *[]*string, exclude *[]*string) *bool
	// Returns true if there are any tags defined.
	HasTags() *bool
	// Removes the specified tag from the array if it exists.
	RemoveTag(key *string, priority *float64)
	// Renders tags into the proper format based on TagType.
	//
	// This method will eagerly render the tags currently applied. In
	// most cases, you should be using `tagManager.renderedTags` instead,
	// which will return a `Lazy` value that will resolve to the correct
	// tags at synthesis time.
	RenderTags() interface{}
	// Adds the specified tag to the array of tags.
	SetTag(key *string, value *string, priority *float64, applyToLaunchedInstances *bool)
	// Render the tags in a readable format.
	TagValues() *map[string]*string
}

TagManager facilitates a common implementation of tagging for Constructs.

Normally, you do not need to use this class, as the CloudFormation specification will indicate which resources are taggable. However, sometimes you will need this to make custom resources taggable. Used `tagManager.renderedTags` to obtain a value that will resolve to the tags at synthesis time.

Example: 

// Example automatically generated from non-compiling source. May contain errors.
import cdk "github.com/aws-samples/dummy/awscdkcore"

type myConstruct struct {
	resource
	tags
}

func newMyConstruct(scope cdk.Construct, id *string) *myConstruct {
	this := &myConstruct{}

	//
	// An empty array will allow this tag to be applied to all resources. A
	// non-empty array will apply this tag only if the Resource type is not in
	// this array.
	ExcludeResourceTypes *[]*string `field:"optional" json:"excludeResourceTypes" yaml:"excludeResourceTypes"`
	// An array of Resource Types that will receive this tag.
	//
	// An empty array will match any Resource. A non-empty array will apply this
	// tag only to Resource types that are included in this array.
	IncludeResourceTypes *[]*string `field:"optional" json:"includeResourceTypes" yaml:"includeResourceTypes"`
	// Priority of the tag operation.
	//
	// Higher or equal priority tags will take precedence.
	//
	// Setting priority will enable the user to control tags when they need to not
	// follow the default precedence pattern of last applied and closest to the
	// construct in the tree.
