A CloudFormation `AWS::Lambda::Alias`.

The `AWS::Lambda::Alias` resource creates an [alias](https://docs.aws.amazon.com/lambda/latest/dg/configuration-aliases.html) for a Lambda function version. Use aliases to provide clients with a function identifier that you can update to invoke a different version.

You can also map an alias to split invocation requests between two versions. Use the `RoutingConfig` parameter to specify a second version and the percentage of invocation requests that it receives.

Example: 

import awscdk "github.com/aws/aws-cdk-go/awscdk"import lambda "github.com/aws/aws-cdk-go/awscdk/aws_lambda"
cfnAlias := lambda.NewCfnAlias(this, jsii.String("MyCfnAlias"), &cfnAliasProps{
	functionName: jsii.String("functionName"),
	functionVersion: jsii.String("functionVersion"),
	name: jsii.String("name"),

	// the properties below are optional
	description: jsii.String("description"),
	provisionedConcurrencyConfig: &provisionedConcurrencyConfigurationProperty{
		provisionedConcurrentExecutions: jsii.Number(123),

A CloudFormation `AWS::Lambda::EventInvokeConfig`.

The `AWS::Lambda::EventInvokeConfig` resource configures options for [asynchronous invocation](https://docs.aws.amazon.com/lambda/latest/dg/invocation-async.html) on a version or an alias.

By default, Lambda retries an asynchronous invocation twice if the function returns an error. It retains events in a queue for up to six hours. When an event fails all processing attempts or stays in the asynchronous invocation queue for too long, Lambda discards it.

Example: 

import awscdk "github.com/aws/aws-cdk-go/awscdk"import lambda "github.com/aws/aws-cdk-go/awscdk/aws_lambda"
cfnEventInvokeConfig := lambda.NewCfnEventInvokeConfig(this, jsii.String("MyCfnEventInvokeConfig"), &cfnEventInvokeConfigProps{
	functionName: jsii.String("functionName"),
	qualifier: jsii.String("qualifier"),

	// the properties below are optional
	destinationConfig: &destinationConfigProperty{
		onFailure: &onFailureProperty{
			destination: jsii.String("destination"),

A CloudFormation `AWS::Lambda::Function`.

The `AWS::Lambda::Function` resource creates a Lambda function. To create a function, you need a [deployment package](https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-package.html) and an [execution role](https://docs.aws.amazon.com/lambda/latest/dg/lambda-intro-execution-role.html) . The deployment package is a .zip file archive or container image that contains your function code. The execution role grants the function permission to use AWS services, such as Amazon CloudWatch Logs for log streaming and AWS X-Ray for request tracing.

You set the package type to `Image` if the deployment package is a [container image](https://docs.aws.amazon.com/lambda/latest/dg/lambda-images.html) . For a container image, the code property must include the URI of a container image in the Amazon ECR registry. You do not need to specify the handler and runtime properties.

You set the package type to `Zip` if the deployment package is a [.zip file archive](https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-package.html#gettingstarted-package-zip) . For a .zip file archive, the code property specifies the location of the .zip file. You must also specify the handler and runtime properties. For a Python example, see [Deploy Python Lambda functions with .zip file archives](https://docs.aws.amazon.com/lambda/latest/dg/python-package.html) .

You can use [code signing](https://docs.aws.amazon.com/lambda/latest/dg/configuration-codesigning.html) if your deployment package is a .zip file archive. To enable code signing for this function, specify the ARN of a code-signing configuration. When a user attempts to deploy a code package with `UpdateFunctionCode` , Lambda checks that the code package has a valid signature from a trusted publisher. The code-signing configuration includes a set of signing profiles, which define the trusted publishers for this function.

Note that you configure [provisioned concurrency](https://docs.aws.amazon.com/lambda/latest/dg/configuration-concurrency.html) on a `AWS::Lambda::Version` or a `AWS::Lambda::Alias` .

For a complete introduction to Lambda functions, see [What is Lambda?](https://docs.aws.amazon.com/lambda/latest/dg/lambda-welcome.html) in the *Lambda developer guide.*

type CfnFunction_CodeProperty 

type CfnFunction_CodeProperty struct {
	// URI of a [container image](https://docs.aws.amazon.com/lambda/latest/dg/lambda-images.html) in the Amazon ECR registry.
	ImageUri *string `json:"imageUri" yaml:"imageUri"`
	// An Amazon S3 bucket in the same AWS Region as your function.

	// The Amazon S3 key of the deployment package.
	S3Key *string `json:"s3Key" yaml:"s3Key"`
	// For versioned objects, the version of the deployment package object to use.
	S3ObjectVersion *string `json:"s3ObjectVersion" yaml:"s3ObjectVersion"`
	// (Node.js and Python) The source code of your Lambda function. If you include your function source inline with this parameter, AWS CloudFormation places it in a file named `index` and zips it to create a [deployment package](https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-package.html) . For the `Handler` property, the first part of the handler identifier must be `index` . For example, `index.handler` .
	//
	// Your source code can contain up to 4096 characters. For JSON, you must escape quotes and special characters such as newline ( `\n` ) with a backslash.
	//
	// If you specify a function that interacts with an AWS CloudFormation custom resource, you don't have to write your own functions to send responses to the custom resource that invoked the function. AWS CloudFormation provides a response module ( [cfn-response](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-lambda-function-code-cfnresponsemodule.html) ) that simplifies sending responses. See [Using AWS Lambda with AWS CloudFormation](https://docs.aws.amazon.com/lambda/latest/dg/services-cloudformation.html) for details.
	ZipFile *string `json:"zipFile" yaml:"zipFile"`
}

The [deployment package](https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-package.html) for a Lambda function. To deploy a function defined as a container image, you specify the location of a container image in the Amazon ECR registry. For a .zip file deployment package, you can specify the location of an object in Amazon S3. For Node.js and Python functions, you can specify the function code inline in the template.

Changes to a deployment package in Amazon S3 are not detected automatically during stack updates. To update the function code, change the object key or version in the template.

Example: 

import awscdk "github.com/aws/aws-cdk-go/awscdk"import lambda "github.com/aws/aws-cdk-go/awscdk/aws_lambda"
codeProperty := &codeProperty{
	imageUri: jsii.String("imageUri"),
	s3Bucket: jsii.String("s3Bucket"),

type CfnFunction_DeadLetterConfigProperty struct {
	// The Amazon Resource Name (ARN) of an Amazon SQS queue or Amazon SNS topic.
	TargetArn *string `json:"targetArn" yaml:"targetArn"`
}

The [dead-letter queue](https://docs.aws.amazon.com/lambda/latest/dg/invocation-async.html#dlq) for failed asynchronous invocations.

Example: 

import awscdk "github.com/aws/aws-cdk-go/awscdk"import lambda "github.com/aws/aws-cdk-go/awscdk/aws_lambda"
deadLetterConfigProperty := &deadLetterConfigProperty{
	targetArn: jsii.String("targetArn"),
}

type CfnFunction_EnvironmentProperty 

type CfnFunction_EnvironmentProperty struct {
	// Environment variable key-value pairs.
	//
	// For more information, see [Using Lambda environment variables](https://docs.aws.amazon.com/lambda/latest/dg/configuration-envvars.html) .
	Variables interface{} `json:"variables" yaml:"variables"`
}

A function's environment variable settings.

You can use environment variables to adjust your function's behavior without updating code. An environment variable is a pair of strings that are stored in a function's version-specific configuration.

Example: 

import awscdk "github.com/aws/aws-cdk-go/awscdk"import lambda "github.com/aws/aws-cdk-go/awscdk/aws_lambda"
environmentProperty := &environmentProperty{
	variables: map[string]*string{
		"variablesKey": jsii.String("variables"),
	},
}

type CfnFunction_EphemeralStorageProperty added in v2.18.0 

type CfnFunction_EphemeralStorageProperty struct {
	// The size of the function’s /tmp directory.
	Size *float64 `json:"size" yaml:"size"`
}

The size of the function’s /tmp directory in MB.

The default value is 512, but can be any whole number between 512 and 10240 MB.

Example: 

import awscdk "github.com/aws/aws-cdk-go/awscdk"import lambda "github.com/aws/aws-cdk-go/awscdk/aws_lambda"
ephemeralStorageProperty := &ephemeralStorageProperty{
	size: jsii.Number(123),
}

type CfnFunction_FileSystemConfigProperty 

type CfnFunction_FileSystemConfigProperty struct {
	// The Amazon Resource Name (ARN) of the Amazon EFS access point that provides access to the file system.
	Arn *string `json:"arn" yaml:"arn"`
	// The path where the function can access the file system, starting with `/mnt/` .
	LocalMountPath *string `json:"localMountPath" yaml:"localMountPath"`
}

Details about the connection between a Lambda function and an [Amazon EFS file system](https://docs.aws.amazon.com/lambda/latest/dg/configuration-filesystem.html) .

Example: 

import awscdk "github.com/aws/aws-cdk-go/awscdk"import lambda "github.com/aws/aws-cdk-go/awscdk/aws_lambda"
fileSystemConfigProperty := &fileSystemConfigProperty{
	arn: jsii.String("arn"),
	localMountPath: jsii.String("localMountPath"),
}

type CfnFunction_ImageConfigProperty 

type CfnFunction_ImageConfigProperty struct {
	// Specifies parameters that you want to pass in with ENTRYPOINT.
	Command *[]*string `json:"command" yaml:"command"`
	// Specifies the entry point to their application, which is typically the location of the runtime executable.
	EntryPoint *[]*string `json:"entryPoint" yaml:"entryPoint"`
	// Specifies the working directory.
	WorkingDirectory *string `json:"workingDirectory" yaml:"workingDirectory"`
}

Configuration values that override the container image Dockerfile settings.

See [Container settings](https://docs.aws.amazon.com/lambda/latest/dg/images-create.html#images-parms) .

Example: 

import awscdk "github.com/aws/aws-cdk-go/awscdk"import lambda "github.com/aws/aws-cdk-go/awscdk/aws_lambda"
imageConfigProperty := &imageConfigProperty{
	command: []*string{
		jsii.String("command"),
	},
	entryPoint: []*string{
		jsii.String("entryPoint"),
	},
	workingDirectory: jsii.String("workingDirectory"),
}

type CfnFunction_TracingConfigProperty 

type CfnFunction_TracingConfigProperty struct {
	// The tracing mode.
	Mode *string `json:"mode" yaml:"mode"`
}

The function's [AWS X-Ray](https://docs.aws.amazon.com/lambda/latest/dg/services-xray.html) tracing configuration. To sample and record incoming requests, set `Mode` to `Active` .

Example: 

import awscdk "github.com/aws/aws-cdk-go/awscdk"import lambda "github.com/aws/aws-cdk-go/awscdk/aws_lambda"
tracingConfigProperty := &tracingConfigProperty{
	mode: jsii.String("mode"),
}

type CfnFunction_VpcConfigProperty 

type CfnFunction_VpcConfigProperty struct {
	// A list of VPC security groups IDs.
	SecurityGroupIds *[]*string `json:"securityGroupIds" yaml:"securityGroupIds"`
	// A list of VPC subnet IDs.
	SubnetIds *[]*string `json:"subnetIds" yaml:"subnetIds"`
}

The VPC security groups and subnets that are attached to a Lambda function.

When you connect a function to a VPC, Lambda creates an elastic network interface for each combination of security group and subnet in the function's VPC configuration. The function can only access resources and the internet through that VPC. For more information, see [VPC Settings](https://docs.aws.amazon.com/lambda/latest/dg/configuration-vpc.html) .

> When you delete a function, AWS CloudFormation monitors the state of its network interfaces and waits for Lambda to delete them before proceeding. If the VPC is defined in the same stack, the network interfaces need to be deleted by Lambda before AWS CloudFormation can delete the VPC's resources. > > To monitor network interfaces, AWS CloudFormation needs the `ec2:DescribeNetworkInterfaces` permission. It obtains this from the user or role that modifies the stack. If you don't provide this permission, AWS CloudFormation does not wait for network interfaces to be deleted.

Example: 

import awscdk "github.com/aws/aws-cdk-go/awscdk"import lambda "github.com/aws/aws-cdk-go/awscdk/aws_lambda"
vpcConfigProperty := &vpcConfigProperty{
	securityGroupIds: []*string{

A CloudFormation `AWS::Lambda::LayerVersionPermission`.

The `AWS::Lambda::LayerVersionPermission` resource adds permissions to the resource-based policy of a version of an [Lambda layer](https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html) . Use this action to grant layer usage permission to other accounts. You can grant permission to a single account, all AWS accounts, or all accounts in an organization.

> Since the release of the [UpdateReplacePolicy](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-updatereplacepolicy.html) both `UpdateReplacePolicy` and `DeletionPolicy` are required to protect your Resources/LayerPermissions from deletion.

Example: 

import awscdk "github.com/aws/aws-cdk-go/awscdk"import lambda "github.com/aws/aws-cdk-go/awscdk/aws_lambda"
cfnLayerVersionPermission := lambda.NewCfnLayerVersionPermission(this, jsii.String("MyCfnLayerVersionPermission"), &cfnLayerVersionPermissionProps{

A CloudFormation `AWS::Lambda::Permission`.

The `AWS::Lambda::Permission` resource grants an AWS service or another account permission to use a function. You can apply the policy at the function level, or specify a qualifier to restrict access to a single version or alias. If you use a qualifier, the invoker must use the full Amazon Resource Name (ARN) of that version or alias to invoke the function.

To grant permission to another account, specify the account ID as the `Principal` . To grant permission to an organization defined in AWS Organizations , specify the organization ID as the `PrincipalOrgID` . For AWS services, the principal is a domain-style identifier defined by the service, like `s3.amazonaws.com` or `sns.amazonaws.com` . For AWS services, you can also specify the ARN of the associated resource as the `SourceArn` . If you grant permission to a service principal without specifying the source, other accounts could potentially configure resources in their account to invoke your Lambda function.

If your function has a function URL, you can specify the `FunctionUrlAuthType` parameter. This adds a condition to your permission that only applies when your function URL's `AuthType` matches the specified `FunctionUrlAuthType` . For more information about the `AuthType` parameter, see [Security and auth model for Lambda function URLs](https://docs.aws.amazon.com/lambda/latest/dg/urls-auth.html) .

This resource adds a statement to a resource-based permission policy for the function. For more information about function policies, see [Lambda Function Policies](https://docs.aws.amazon.com/lambda/latest/dg/access-control-resource-based.html) .

Example: 

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

Configure options for asynchronous invocation on a version or an alias.

By default, Lambda retries an asynchronous invocation twice if the function returns an error. It retains events in a queue for up to six hours. When an event fails all processing attempts or stays in the asynchronous invocation queue for too long, Lambda discards it.

Example: 

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

Defines a Lambda EventSourceMapping resource.

Usually, you won't need to define the mapping yourself. This will usually be done by event sources. For example, to add an SQS event source to a function: 

import { SqsEventSource } from '@aws-cdk/aws-lambda-event-sources';
lambda.addEventSource(new SqsEventSource(sqs));

The `SqsEventSource` class will automatically create the mapping, and will also modify the Lambda's execution role so it can consume messages from the queue.

Example: 

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

	//
	// The principal can be either an AccountPrincipal or a ServicePrincipal.
	Principal awsiam.IPrincipal `json:"principal" yaml:"principal"`
	// The Lambda actions that you want to allow in this statement.
	//
	// For example,
	// you can specify lambda:CreateFunction to specify a certain action, or use

	// source principals are owned by a specific account.
	SourceAccount *string `json:"sourceAccount" yaml:"sourceAccount"`

	// any bucket from any AWS account that creates a mapping to your function,
	// can invoke the function.
	SourceArn *string `json:"sourceArn" yaml:"sourceArn"`
}

Represents a permission statement that can be added to a Lambda function's resource policy via the `addPermission()` method.

A Lambda that will only ever be added to a stack once.

This construct is a way to guarantee that the lambda function will be guaranteed to be part of the stack, once and only once, irrespective of how many times the construct is declared to be part of the stack. This is guaranteed as long as the `uuid` property and the optional `lambdaPurpose` property stay the same whenever they're declared into the stack.

}

Tag the current state of a Function with a Version number.

Avoid using this resource directly. If you need a Version object, use `function.currentVersion` instead. That will add a Version object to your template, and make sure the Version is invalidated whenever the Function object changes. If you use the `Version` resource directly, you are responsible for making sure it is invalidated (by changing its logical ID) whenever necessary.

Version resources can then be used in `Alias` resources to refer to a particular deployment of a Lambda.

If you want to ensure that you're associating the right version with the right deployment, specify the `codeSha256` property while creating the `Version.

Example: 

// Example automatically generated from non-compiling source. May contain errors.
lambdaCode := lambda.code.fromCfnParameters()
func := lambda.NewFunction(this, jsii.String("Lambda"), &functionProps{
	code: lambdaCode,
	handler: jsii.String("index.handler"),
	runtime: lambda.runtime_NODEJS_12_X(),
})
// used to make sure each CDK synthesis produces a different Version
version := func.currentVersion
alias := lambda.NewAlias(this, jsii.String("LambdaAlias"), &aliasProps{
	aliasName: jsii.String("Prod"),
	version: version,
})
