Amazon Elastic Load Balancing V2 Construct Library

The @aws-cdk/aws-elasticloadbalancingv2 package provides constructs for configuring application and network load balancers.

For more information, see the AWS documentation for Application Load Balancers and Network Load Balancers.

Defining an Application Load Balancer

You define an application load balancer by creating an instance of ApplicationLoadBalancer, adding a Listener to the load balancer and adding Targets to the Listener:

import "github.com/aws/aws-cdk-go/awscdk"
var asg autoScalingGroup

var vpc vpc


// Create the load balancer in a VPC. 'internetFacing' is 'false'
// by default, which creates an internal load balancer.
lb := elbv2.NewApplicationLoadBalancer(this, jsii.String("LB"), &applicationLoadBalancerProps{
	vpc: vpc,
	internetFacing: jsii.Boolean(true),
})

// Add a listener and open up the load balancer's security group
// to the world.
listener := lb.addListener(jsii.String("Listener"), &baseApplicationListenerProps{
	port: jsii.Number(80),

	// 'open: true' is the default, you can leave it out if you want. Set it
	// to 'false' and use `listener.connections` if you want to be selective
	// about who can access the load balancer.
	open: jsii.Boolean(true),
})

// Create an AutoScaling group and add it as a load balancing
// target to the listener.
listener.addTargets(jsii.String("ApplicationFleet"), &addApplicationTargetsProps{
	port: jsii.Number(8080),
	targets: []iApplicationLoadBalancerTarget{
		asg,
	},
})

The security groups of the load balancer and the target are automatically updated to allow the network traffic.

One (or more) security groups can be associated with the load balancer; if a security group isn't provided, one will be automatically created.

var vpc vpc


securityGroup1 := ec2.NewSecurityGroup(this, jsii.String("SecurityGroup1"), &securityGroupProps{
	vpc: vpc,
})
lb := elbv2.NewApplicationLoadBalancer(this, jsii.String("LB"), &applicationLoadBalancerProps{
	vpc: vpc,
	internetFacing: jsii.Boolean(true),
	securityGroup: securityGroup1,
})

securityGroup2 := ec2.NewSecurityGroup(this, jsii.String("SecurityGroup2"), &securityGroupProps{
	vpc: vpc,
})
lb.addSecurityGroup(securityGroup2)
Conditions

It's possible to route traffic to targets based on conditions in the incoming HTTP request. For example, the following will route requests to the indicated AutoScalingGroup only if the requested host in the request is either for example.com/ok or example.com/path:

var listener applicationListener
var asg autoScalingGroup


listener.addTargets(jsii.String("Example.Com Fleet"), &addApplicationTargetsProps{
	priority: jsii.Number(10),
	conditions: []listenerCondition{
		elbv2.*listenerCondition.hostHeaders([]*string{
			jsii.String("example.com"),
		}),
		elbv2.*listenerCondition.pathPatterns([]*string{
			jsii.String("/ok"),
			jsii.String("/path"),
		}),
	},
	port: jsii.Number(8080),
	targets: []iApplicationLoadBalancerTarget{
		asg,
	},
})

A target with a condition contains either pathPatterns or hostHeader, or both. If both are specified, both conditions must be met for the requests to be routed to the given target. priority is a required field when you add targets with conditions. The lowest number wins.

Every listener must have at least one target without conditions, which is where all requests that didn't match any of the conditions will be sent.

Convenience methods and more complex Actions

Routing traffic from a Load Balancer to a Target involves the following steps:

  • Create a Target Group, register the Target into the Target Group
  • Add an Action to the Listener which forwards traffic to the Target Group.

A new listener can be added to the Load Balancer by calling addListener(). Listeners that have been added to the load balancer can be listed using the listeners property. Note that the listeners property will throw an Error for imported or looked up Load Balancers.

Various methods on the Listener take care of this work for you to a greater or lesser extent:

  • addTargets() performs both steps: automatically creates a Target Group and the required Action.
  • addTargetGroups() gives you more control: you create the Target Group (or Target Groups) yourself and the method creates Action that routes traffic to the Target Groups.
  • addAction() gives you full control: you supply the Action and wire it up to the Target Groups yourself (or access one of the other ELB routing features).

Using addAction() gives you access to some of the features of an Elastic Load Balancer that the other two convenience methods don't:

  • Routing stickiness: use ListenerAction.forward() and supply a stickinessDuration to make sure requests are routed to the same target group for a given duration.
  • Weighted Target Groups: use ListenerAction.weightedForward() to give different weights to different target groups.
  • Fixed Responses: use ListenerAction.fixedResponse() to serve a static response (ALB only).
  • Redirects: use ListenerAction.redirect() to serve an HTTP redirect response (ALB only).
  • Authentication: use ListenerAction.authenticateOidc() to perform OpenID authentication before serving a request (see the @aws-cdk/aws-elasticloadbalancingv2-actions package for direct authentication integration with Cognito) (ALB only).

Here's an example of serving a fixed response at the /ok URL:

var listener applicationListener


listener.addAction(jsii.String("Fixed"), &addApplicationActionProps{
	priority: jsii.Number(10),
	conditions: []listenerCondition{
		elbv2.*listenerCondition.pathPatterns([]*string{
			jsii.String("/ok"),
		}),
	},
	action: elbv2.listenerAction.fixedResponse(jsii.Number(200), &fixedResponseOptions{
		contentType: elbv2.contentType_TEXT_PLAIN,
		messageBody: jsii.String("OK"),
	}),
})

Here's an example of using OIDC authentication before forwarding to a TargetGroup:

var listener applicationListener
var myTargetGroup applicationTargetGroup


listener.addAction(jsii.String("DefaultAction"), &addApplicationActionProps{
	action: elbv2.listenerAction.authenticateOidc(&authenticateOidcOptions{
		authorizationEndpoint: jsii.String("https://example.com/openid"),
		// Other OIDC properties here
		clientId: jsii.String("..."),
		clientSecret: awscdk.SecretValue.secretsManager(jsii.String("...")),
		issuer: jsii.String("..."),
		tokenEndpoint: jsii.String("..."),
		userInfoEndpoint: jsii.String("..."),

		// Next
		next: elbv2.*listenerAction.forward([]iApplicationTargetGroup{
			myTargetGroup,
		}),
	}),
})

If you just want to redirect all incoming traffic on one port to another port, you can use the following code:

var lb applicationLoadBalancer


lb.addRedirect(&applicationLoadBalancerRedirectConfig{
	sourceProtocol: elbv2.applicationProtocol_HTTPS,
	sourcePort: jsii.Number(8443),
	targetProtocol: elbv2.*applicationProtocol_HTTP,
	targetPort: jsii.Number(8080),
})

If you do not provide any options for this method, it redirects HTTP port 80 to HTTPS port 443.

By default all ingress traffic will be allowed on the source port. If you want to be more selective with your ingress rules then set open: false and use the listener's connections object to selectively grant access to the listener.

Defining a Network Load Balancer

Network Load Balancers are defined in a similar way to Application Load Balancers:

var vpc vpc
var asg autoScalingGroup


// Create the load balancer in a VPC. 'internetFacing' is 'false'
// by default, which creates an internal load balancer.
lb := elbv2.NewNetworkLoadBalancer(this, jsii.String("LB"), &networkLoadBalancerProps{
	vpc: vpc,
	internetFacing: jsii.Boolean(true),
})

// Add a listener on a particular port.
listener := lb.addListener(jsii.String("Listener"), &baseNetworkListenerProps{
	port: jsii.Number(443),
})

// Add targets on a particular port.
listener.addTargets(jsii.String("AppFleet"), &addNetworkTargetsProps{
	port: jsii.Number(443),
	targets: []iNetworkLoadBalancerTarget{
		asg,
	},
})

One thing to keep in mind is that network load balancers do not have security groups, and no automatic security group configuration is done for you. You will have to configure the security groups of the target yourself to allow traffic by clients and/or load balancer instances, depending on your target types. See Target Groups for your Network Load Balancers and Register targets with your Target Group for more information.

Targets and Target Groups

Application and Network Load Balancers organize load balancing targets in Target Groups. If you add your balancing targets (such as AutoScalingGroups, ECS services or individual instances) to your listener directly, the appropriate TargetGroup will be automatically created for you.

If you need more control over the Target Groups created, create an instance of ApplicationTargetGroup or NetworkTargetGroup, add the members you desire, and add it to the listener by calling addTargetGroups instead of addTargets.

addTargets() will always return the Target Group it just created for you:

var listener networkListener
var asg1 autoScalingGroup
var asg2 autoScalingGroup


group := listener.addTargets(jsii.String("AppFleet"), &addNetworkTargetsProps{
	port: jsii.Number(443),
	targets: []iNetworkLoadBalancerTarget{
		asg1,
	},
})

group.addTarget(asg2)
Sticky sessions for your Application Load Balancer

By default, an Application Load Balancer routes each request independently to a registered target based on the chosen load-balancing algorithm. However, you can use the sticky session feature (also known as session affinity) to enable the load balancer to bind a user's session to a specific target. This ensures that all requests from the user during the session are sent to the same target. This feature is useful for servers that maintain state information in order to provide a continuous experience to clients. To use sticky sessions, the client must support cookies.

Application Load Balancers support both duration-based cookies (lb_cookie) and application-based cookies (app_cookie). The key to managing sticky sessions is determining how long your load balancer should consistently route the user's request to the same target. Sticky sessions are enabled at the target group level. You can use a combination of duration-based stickiness, application-based stickiness, and no stickiness across all of your target groups.

var vpc vpc


// Target group with duration-based stickiness with load-balancer generated cookie
tg1 := elbv2.NewApplicationTargetGroup(this, jsii.String("TG1"), &applicationTargetGroupProps{
	targetType: elbv2.targetType_INSTANCE,
	port: jsii.Number(80),
	stickinessCookieDuration: awscdk.Duration.minutes(jsii.Number(5)),
	vpc: vpc,
})

// Target group with application-based stickiness
tg2 := elbv2.NewApplicationTargetGroup(this, jsii.String("TG2"), &applicationTargetGroupProps{
	targetType: elbv2.*targetType_INSTANCE,
	port: jsii.Number(80),
	stickinessCookieDuration: awscdk.Duration.minutes(jsii.Number(5)),
	stickinessCookieName: jsii.String("MyDeliciousCookie"),
	vpc: vpc,
})

For more information see: https://docs.aws.amazon.com/elasticloadbalancing/latest/application/sticky-sessions.html#application-based-stickiness

Setting the target group protocol version

By default, Application Load Balancers send requests to targets using HTTP/1.1. You can use the protocol version to send requests to targets using HTTP/2 or gRPC.

var vpc vpc


tg := elbv2.NewApplicationTargetGroup(this, jsii.String("TG"), &applicationTargetGroupProps{
	targetType: elbv2.targetType_IP,
	port: jsii.Number(50051),
	protocol: elbv2.applicationProtocol_HTTP,
	protocolVersion: elbv2.applicationProtocolVersion_GRPC,
	healthCheck: &healthCheck{
		enabled: jsii.Boolean(true),
		healthyGrpcCodes: jsii.String("0-99"),
	},
	vpc: vpc,
})

Using Lambda Targets

To use a Lambda Function as a target, use the integration class in the @aws-cdk/aws-elasticloadbalancingv2-targets package:

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

var lambdaFunction function
var lb applicationLoadBalancer


listener := lb.addListener(jsii.String("Listener"), &baseApplicationListenerProps{
	port: jsii.Number(80),
})
listener.addTargets(jsii.String("Targets"), &addApplicationTargetsProps{
	targets: []iApplicationLoadBalancerTarget{
		targets.NewLambdaTarget(lambdaFunction),
	},

	// For Lambda Targets, you need to explicitly enable health checks if you
	// want them.
	healthCheck: &healthCheck{
		enabled: jsii.Boolean(true),
	},
})

Only a single Lambda function can be added to a single listener rule.

Using Application Load Balancer Targets

To use a single application load balancer as a target for the network load balancer, use the integration class in the @aws-cdk/aws-elasticloadbalancingv2-targets package:

import targets "github.com/aws/aws-cdk-go/awscdk"
import ecs "github.com/aws/aws-cdk-go/awscdk"
import patterns "github.com/aws/aws-cdk-go/awscdk"

var vpc vpc


task := ecs.NewFargateTaskDefinition(this, jsii.String("Task"), &fargateTaskDefinitionProps{
	cpu: jsii.Number(256),
	memoryLimitMiB: jsii.Number(512),
})
task.addContainer(jsii.String("nginx"), &containerDefinitionOptions{
	image: ecs.containerImage.fromRegistry(jsii.String("public.ecr.aws/nginx/nginx:latest")),
	portMappings: []portMapping{
		&portMapping{
			containerPort: jsii.Number(80),
		},
	},
})

svc := patterns.NewApplicationLoadBalancedFargateService(this, jsii.String("Service"), &applicationLoadBalancedFargateServiceProps{
	vpc: vpc,
	taskDefinition: task,
	publicLoadBalancer: jsii.Boolean(false),
})

nlb := elbv2.NewNetworkLoadBalancer(this, jsii.String("Nlb"), &networkLoadBalancerProps{
	vpc: vpc,
	crossZoneEnabled: jsii.Boolean(true),
	internetFacing: jsii.Boolean(true),
})

listener := nlb.addListener(jsii.String("listener"), &baseNetworkListenerProps{
	port: jsii.Number(80),
})

listener.addTargets(jsii.String("Targets"), &addNetworkTargetsProps{
	targets: []iNetworkLoadBalancerTarget{
		targets.NewAlbTarget(svc.loadBalancer, jsii.Number(80)),
	},
	port: jsii.Number(80),
})

awscdk.NewCfnOutput(this, jsii.String("NlbEndpoint"), &cfnOutputProps{
	value: fmt.Sprintf("http://%v", nlb.loadBalancerDnsName),
})

Only the network load balancer is allowed to add the application load balancer as the target.

Configuring Health Checks

Health checks are configured upon creation of a target group:

var listener applicationListener
var asg autoScalingGroup


listener.addTargets(jsii.String("AppFleet"), &addApplicationTargetsProps{
	port: jsii.Number(8080),
	targets: []iApplicationLoadBalancerTarget{
		asg,
	},
	healthCheck: &healthCheck{
		path: jsii.String("/ping"),
		interval: awscdk.Duration.minutes(jsii.Number(1)),
	},
})

The health check can also be configured after creation by calling configureHealthCheck() on the created object.

No attempts are made to configure security groups for the port you're configuring a health check for, but if the health check is on the same port you're routing traffic to, the security group already allows the traffic. If not, you will have to configure the security groups appropriately:

var lb applicationLoadBalancer
var listener applicationListener
var asg autoScalingGroup


listener.addTargets(jsii.String("AppFleet"), &addApplicationTargetsProps{
	port: jsii.Number(8080),
	targets: []iApplicationLoadBalancerTarget{
		asg,
	},
	healthCheck: &healthCheck{
		port: jsii.String("8088"),
	},
})

asg.connections.allowFrom(lb, ec2.port.tcp(jsii.Number(8088)))

Using a Load Balancer from a different Stack

If you want to put your Load Balancer and the Targets it is load balancing to in different stacks, you may not be able to use the convenience methods loadBalancer.addListener() and listener.addTargets().

The reason is that these methods will create resources in the same Stack as the object they're called on, which may lead to cyclic references between stacks. Instead, you will have to create an ApplicationListener in the target stack, or an empty TargetGroup in the load balancer stack that you attach your service to.

For an example of the alternatives while load balancing to an ECS service, see the ecs/cross-stack-load-balancer example.

Protocol for Load Balancer Targets

Constructs that want to be a load balancer target should implement IApplicationLoadBalancerTarget and/or INetworkLoadBalancerTarget, and provide an implementation for the function attachToXxxTargetGroup(), which can call functions on the load balancer and should return metadata about the load balancing target:

type myTarget struct {
}

func (this *myTarget) attachToApplicationTargetGroup(targetGroup applicationTargetGroup) loadBalancerTargetProps {
	// If we need to add security group rules
	// targetGroup.registerConnectable(...);
	return &loadBalancerTargetProps{
		targetType: elbv2.targetType_IP,
		targetJson: map[string]interface{}{
			"id": jsii.String("1.2.3.4"),
			"port": jsii.Number(8080),
		},
	}
}

targetType should be one of Instance or Ip. If the target can be directly added to the target group, targetJson should contain the id of the target (either instance ID or IP address depending on the type) and optionally a port or availabilityZone override.

Application load balancer targets can call registerConnectable() on the target group to register themselves for addition to the load balancer's security group rules.

If your load balancer target requires that the TargetGroup has been associated with a LoadBalancer before registration can happen (such as is the case for ECS Services for example), take a resource dependency on targetGroup.loadBalancerAttached as follows:

var resource resource
var targetGroup applicationTargetGroup


// Make sure that the listener has been created, and so the TargetGroup
// has been associated with the LoadBalancer, before 'resource' is created.

constructs.Node.of(resource).addDependency(targetGroup.loadBalancerAttached)

Looking up Load Balancers and Listeners

You may look up load balancers and load balancer listeners by using one of the following lookup methods:

  • ApplicationLoadBalancer.fromlookup(options) - Look up an application load balancer.
  • ApplicationListener.fromLookup(options) - Look up an application load balancer listener.
  • NetworkLoadBalancer.fromLookup(options) - Look up a network load balancer.
  • NetworkListener.fromLookup(options) - Look up a network load balancer listener.
Load Balancer lookup options

You may look up a load balancer by ARN or by associated tags. When you look a load balancer up by ARN, that load balancer will be returned unless CDK detects that the load balancer is of the wrong type. When you look up a load balancer by tags, CDK will return the load balancer matching all specified tags. If more than one load balancer matches, CDK will throw an error requesting that you provide more specific criteria.

Look up a Application Load Balancer by ARN

loadBalancer := elbv2.applicationLoadBalancer.fromLookup(this, jsii.String("ALB"), &applicationLoadBalancerLookupOptions{
	loadBalancerArn: jsii.String("arn:aws:elasticloadbalancing:us-east-2:123456789012:loadbalancer/app/my-load-balancer/1234567890123456"),
})

Look up an Application Load Balancer by tags

loadBalancer := elbv2.applicationLoadBalancer.fromLookup(this, jsii.String("ALB"), &applicationLoadBalancerLookupOptions{
	loadBalancerTags: map[string]*string{
		// Finds a load balancer matching all tags.
		"some": jsii.String("tag"),
		"someother": jsii.String("tag"),
	},
})

Load Balancer Listener lookup options

You may look up a load balancer listener by the following criteria:

  • Associated load balancer ARN
  • Associated load balancer tags
  • Listener ARN
  • Listener port
  • Listener protocol

The lookup method will return the matching listener. If more than one listener matches, CDK will throw an error requesting that you specify additional criteria.

Look up a Listener by associated Load Balancer, Port, and Protocol

listener := elbv2.applicationListener.fromLookup(this, jsii.String("ALBListener"), &applicationListenerLookupOptions{
	loadBalancerArn: jsii.String("arn:aws:elasticloadbalancing:us-east-2:123456789012:loadbalancer/app/my-load-balancer/1234567890123456"),
	listenerProtocol: elbv2.applicationProtocol_HTTPS,
	listenerPort: jsii.Number(443),
})

Look up a Listener by associated Load Balancer Tag, Port, and Protocol

listener := elbv2.applicationListener.fromLookup(this, jsii.String("ALBListener"), &applicationListenerLookupOptions{
	loadBalancerTags: map[string]*string{
		"Cluster": jsii.String("MyClusterName"),
	},
	listenerProtocol: elbv2.applicationProtocol_HTTPS,
	listenerPort: jsii.Number(443),
})

Look up a Network Listener by associated Load Balancer Tag, Port, and Protocol

listener := elbv2.networkListener.fromLookup(this, jsii.String("ALBListener"), &networkListenerLookupOptions{
	loadBalancerTags: map[string]*string{
		"Cluster": jsii.String("MyClusterName"),
	},
	listenerProtocol: elbv2.protocol_TCP,
	listenerPort: jsii.Number(12345),
})

	// If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.
	Values interface{} `field:"optional" json:"values" yaml:"values"`
}

Information about a query string condition.

The query string component of a URI starts after the first '?' character and is terminated by either a '#' character or the end of the URI. A typical query string contains key/value pairs separated by '&' characters. The allowed characters are specified by RFC 3986. Any character can be percentage encoded.

	Query *string `field:"optional" json:"query" yaml:"query"`
}

Information about a redirect action.

A URI consists of the following components: protocol://hostname:port/path?query. You must modify at least one of the following components to avoid a redirect loop: protocol, hostname, port, or path. Any components that you do not modify retain their original values.

You can reuse URI components using the following reserved keywords:

- #{protocol} - #{host} - #{port} - #{path} (the leading "/" is removed) - #{query}

For example, you can change the path to "/new/#{path}", the hostname to "example.#{host}", or the query to "#{query}&value=xyz".

	Query *string `field:"optional" json:"query" yaml:"query"`
}

Information about a redirect action.

A URI consists of the following components: protocol://hostname:port/path?query. You must modify at least one of the following components to avoid a redirect loop: protocol, hostname, port, or path. Any components that you do not modify retain their original values.

You can reuse URI components using the following reserved keywords:

- #{protocol} - #{host} - #{port} - #{path} (the leading "/" is removed) - #{query}

For example, you can change the path to "/new/#{path}", the hostname to "example.#{host}", or the query to "#{query}&value=xyz".

	// - `access_logs.s3.bucket` - The name of the S3 bucket for the access logs. This attribute is required if access logs are enabled. The bucket must exist in the same region as the load balancer and have a bucket policy that grants Elastic Load Balancing permissions to write to the bucket.
	// - `access_logs.s3.prefix` - The prefix for the location in the S3 bucket for the access logs.
	// - `ipv6.deny_all_igw_traffic` - Blocks internet gateway (IGW) access to the load balancer. It is set to `false` for internet-facing load balancers and `true` for internal load balancers, preventing unintended access to your internal load balancer through an internet gateway.
	//
	// The following attributes are supported by only Application Load Balancers:
	//
	// - `idle_timeout.timeout_seconds` - The idle timeout value, in seconds. The valid range is 1-4000 seconds. The default is 60 seconds.
	// - `routing.http.desync_mitigation_mode` - Determines how the load balancer handles requests that might pose a security risk to your application. The possible values are `monitor` , `defensive` , and `strictest` . The default is `defensive` .
	// - `routing.http.drop_invalid_header_fields.enabled` - Indicates whether HTTP headers with invalid header fields are removed by the load balancer ( `true` ) or routed to targets ( `false` ). The default is `false` .
	// - `routing.http.preserve_host_header.enabled` - Indicates whether the Application Load Balancer should preserve the `Host` header in the HTTP request and send it to the target without any change. The possible values are `true` and `false` . The default is `false` .
	// - `routing.http.x_amzn_tls_version_and_cipher_suite.enabled` - Indicates whether the two headers ( `x-amzn-tls-version` and `x-amzn-tls-cipher-suite` ), which contain information about the negotiated TLS version and cipher suite, are added to the client request before sending it to the target. The `x-amzn-tls-version` header has information about the TLS protocol version negotiated with the client, and the `x-amzn-tls-cipher-suite` header has information about the cipher suite negotiated with the client. Both headers are in OpenSSL format. The possible values for the attribute are `true` and `false` . The default is `false` .
	// - `routing.http.xff_client_port.enabled` - Indicates whether the `X-Forwarded-For` header should preserve the source port that the client used to connect to the load balancer. The possible values are `true` and `false` . The default is `false` .
	// - `routing.http.xff_header_processing.mode` - Enables you to modify, preserve, or remove the `X-Forwarded-For` header in the HTTP request before the Application Load Balancer sends the request to the target. The possible values are `append` , `preserve` , and `remove` . The default is `append` .
	//
	// - If the value is `append` , the Application Load Balancer adds the client IP address (of the last hop) to the `X-Forwarded-For` header in the HTTP request before it sends it to targets.
	// - If the value is `preserve` the Application Load Balancer preserves the `X-Forwarded-For` header in the HTTP request, and sends it to targets without any change.
	// - If the value is `remove` , the Application Load Balancer removes the `X-Forwarded-For` header in the HTTP request before it sends it to targets.
	// - `routing.http2.enabled` - Indicates whether HTTP/2 is enabled. The possible values are `true` and `false` . The default is `true` . Elastic Load Balancing requires that message header names contain only alphanumeric characters and hyphens.
	// - `waf.fail_open.enabled` - Indicates whether to allow a WAF-enabled load balancer to route requests to targets if it is unable to forward the request to AWS WAF. The possible values are `true` and `false` . The default is `false` .

An EC2 instance that is the target for load balancing.

If you register a target of this type, you are responsible for making sure the load balancer's security group can connect to the instance.

Example: 

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

	// Deprecated: Use IpTarget from the.
	AttachToNetworkTargetGroup(targetGroup INetworkTargetGroup) *LoadBalancerTargetProps
}

An IP address that is a target for load balancing.

Specify IP addresses from the subnets of the virtual private cloud (VPC) for the target group, the RFC 1918 range (10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16), and the RFC 6598 range (100.64.0.0/10). You can't specify publicly routable IP addresses.

If you register a target of this type, you are responsible for making sure the load balancer's security group can send packets to the IP address.

Example: 

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

ipTarget := awscdk.Aws_elasticloadbalancingv2.NewIpTarget(jsii.String("ipAddress"), jsii.Number(123), jsii.String("availabilityZone"))

Deprecated: Use IpTarget from the.

func NewIpTarget 

func NewIpTarget(ipAddress *string, port *float64, availabilityZone *string) IpTarget

Create a new IPAddress target.

The availabilityZone parameter determines whether the target receives traffic from the load balancer nodes in the specified Availability Zone or from all enabled Availability Zones for the load balancer.

This parameter is not supported if the target type of the target group is instance. If the IP address is in a subnet of the VPC for the target group, the Availability Zone is automatically detected and this parameter is optional. If the IP address is outside the VPC, this parameter is required.

With an Application Load Balancer, if the IP address is outside the VPC for the target group, the only supported value is all.

Default is automatic. Deprecated: Use IpTarget from the.

type ListenerAction 

type ListenerAction interface {

	// Render the actions in this chain.
	// Experimental.

	// We don't number for 0 or 1 elements, but otherwise number them 1...#actions
	// so ELB knows about the right order.
	//
	// Do this in `ListenerAction` instead of in `Listener` so that we give
	// users the opportunity to override by subclassing and overriding `renderActions`.
	// Experimental.
	Renumber(actions *[]*CfnListener_ActionProperty) *[]*CfnListener_ActionProperty
}

What to do when a client makes a request to a listener.

Some actions can be combined with other ones (specifically, you can perform authentication before serving the request).

Multiple actions form a linked chain; the chain must always terminate in a *(weighted)forward*, *fixedResponse* or *redirect* action.

If an action supports chaining, the next action can be indicated by passing it in the `next` property.

(Called `ListenerAction` instead of the more strictly correct `ListenerAction` because this is the class most users interact with, and we want to make it not too visually overwhelming).

Example: 

var listener applicationListener
var myTargetGroup applicationTargetGroup

listener.addAction(jsii.String("DefaultAction"), &addApplicationActionProps{
	action: elbv2.listenerAction.authenticateOidc(&authenticateOidcOptions{
		authorizationEndpoint: jsii.String("https://example.com/openid"),
		// Other OIDC properties here
		clientId: jsii.String("..."),
		clientSecret: awscdk.SecretValue.secretsManager(jsii.String("...")),
		issuer: jsii.String("..."),
		tokenEndpoint: jsii.String("..."),

Experimental.

func ListenerAction_Redirect 

func ListenerAction_Redirect(options *RedirectOptions) ListenerAction

Redirect to a different URI.

A URI consists of the following components: protocol://hostname:port/path?query. You must modify at least one of the following components to avoid a redirect loop: protocol, hostname, port, or path. Any components that you do not modify retain their original values.

You can reuse URI components using the following reserved keywords:

- `#{protocol}` - `#{host}` - `#{port}` - `#{path}` (the leading "/" is removed) - `#{query}`

For example, you can change the path to "/new/#{path}", the hostname to "example.#{host}", or the query to "#{query}&value=xyz". See: https://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-listeners.html#redirect-actions

Experimental.

Multiple actions form a linked chain; the chain must always terminate in a *(weighted)forward*, *fixedResponse* or *redirect* action.

If an action supports chaining, the next action can be indicated by passing it in the `next` property.

Example: 

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

Options for `ListenerAction.redirect()`.

A URI consists of the following components: protocol://hostname:port/path?query. You must modify at least one of the following components to avoid a redirect loop: protocol, hostname, port, or path. Any components that you do not modify retain their original values.

You can reuse URI components using the following reserved keywords:

- `#{protocol}` - `#{host}` - `#{port}` - `#{path}` (the leading "/" is removed) - `#{query}`

For example, you can change the path to "/new/#{path}", the hostname to "example.#{host}", or the query to "#{query}&value=xyz".

type SslPolicy 

type SslPolicy string

Elastic Load Balancing provides the following security policies for Application Load Balancers.

We recommend the Recommended policy for general use. You can use the ForwardSecrecy policy if you require Forward Secrecy (FS).

You can use one of the TLS policies to meet compliance and security standards that require disabling certain TLS protocol versions, or to support legacy clients that require deprecated ciphers.

Example: 

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