Actions for AWS Elastic Load Balancing V2

---

End-of-Support

AWS CDK v1 has reached End-of-Support on 2023-06-01. This package is no longer being updated, and users should migrate to AWS CDK v2.

For more information on how to migrate, see the Migrating to AWS CDK v2 guide.

This package contains integration actions for ELBv2. See the README of the @aws-cdk/aws-elasticloadbalancingv2 library.

Cognito

ELB allows for requests to be authenticated against a Cognito user pool using the AuthenticateCognitoAction. For details on the setup's requirements, read Prepare to use Amazon Cognito. Here's an example:

import aws_cdk.aws_cognito as cognito
import aws_cdk.aws_ec2 as ec2
import aws_cdk.aws_elasticloadbalancingv2 as elbv2
from aws_cdk.core import App, CfnOutput, Stack
from constructs import Construct
import aws_cdk.aws_elasticloadbalancingv2_actions as actions

Stack): lb = elbv2.ApplicationLoadBalancer(self, "LB",
    vpc=vpc,
    internet_facing=True
)

user_pool = cognito.UserPool(self, "UserPool")
user_pool_client = cognito.UserPoolClient(self, "Client",
    user_pool=user_pool,

    # Required minimal configuration for use with an ELB
    generate_secret=True,
    auth_flows=cognito.AuthFlow(
        user_password=True
    ),
    o_auth=cognito.OAuthSettings(
        flows=cognito.OAuthFlows(
            authorization_code_grant=True
        ),
        scopes=[cognito.OAuthScope.EMAIL],
        callback_urls=[f"https://{lb.loadBalancerDnsName}/oauth2/idpresponse"
        ]
    )
)
cfn_client = user_pool_client.node.default_child
cfn_client.add_property_override("RefreshTokenValidity", 1)
cfn_client.add_property_override("SupportedIdentityProviders", ["COGNITO"])

user_pool_domain = cognito.UserPoolDomain(self, "Domain",
    user_pool=user_pool,
    cognito_domain=cognito.CognitoDomainOptions(
        domain_prefix="test-cdk-prefix"
    )
)

lb.add_listener("Listener",
    port=443,
    certificates=[certificate],
    default_action=actions.AuthenticateCognitoAction(
        user_pool=user_pool,
        user_pool_client=user_pool_client,
        user_pool_domain=user_pool_domain,
        next=elbv2.ListenerAction.fixed_response(200,
            content_type="text/plain",
            message_body="Authenticated"
        )
    )
)

CfnOutput(self, "DNS",
    value=lb.load_balancer_dns_name
)

app = App()
CognitoStack(app, "integ-cognito")
app.synth()

NOTE: this example seems incomplete, I was not able to get the redirect back to the Load Balancer after authentication working. Would love some pointers on what a full working setup actually looks like!
