	GreenTargetGroup awselasticloadbalancingv2.ITargetGroup `field:"required" json:"greenTargetGroup" yaml:"greenTargetGroup"`

	Listener awselasticloadbalancingv2.IListener `field:"required" json:"listener" yaml:"listener"`
	// Specify how long CodeDeploy waits for approval to continue a blue-green deployment before it stops the deployment.
	//
	// After provisioning the 'green' ECS task set and re-routing test traffic, CodeDeploy can wait for approval before
	// continuing the deployment and re-routing production traffic.  During this wait time, validation such as manual
	// testing or running integration tests can occur using the test traffic port, prior to exposing the new 'green' task
	// set to production traffic.  To approve the deployment, validation steps use the CodeDeploy
	// [ContinueDeployment API(https://docs.aws.amazon.com/codedeploy/latest/APIReference/API_ContinueDeployment.html).
	// If the ContinueDeployment API is not called within the wait time period, CodeDeploy will stop the deployment.
	//
	// By default, CodeDeploy will not wait for deployment approval.  After re-routing test traffic to the 'green' ECS task set
	// and running any 'AfterAllowTestTraffic' and 'BeforeAllowTraffic' lifecycle hooks, the deployment will immediately
	// re-route production traffic to the 'green' ECS task set.

	// Specify how long CodeDeploy waits before it terminates the original 'blue' ECS task set when a blue-green deployment is complete.
	//
	// During this wait time, CodeDeploy will continue to monitor any CloudWatch alarms specified for the deployment group,
	// and the deployment group can be configured to automatically roll back if those alarms fire.  Once CodeDeploy begins to
	// terminate the 'blue' ECS task set, the deployment can no longer be rolled back, manually or automatically.
	//
	// By default, the deployment will immediately terminate the 'blue' ECS task set after production traffic is successfully
	// routed to the 'green' ECS task set.
	TerminationWaitTime awscdk.Duration `field:"optional" json:"terminationWaitTime" yaml:"terminationWaitTime"`
	// The load balancer listener used to route test traffic to the 'green' ECS task set during a blue-green deployment.
	//
	// During a blue-green deployment, validation can occur after test traffic has been re-routed and before production
	// traffic has been re-routed to the 'green' ECS task set.  You can specify one or more Lambda funtions in the
	// deployment's AppSpec file that run during the AfterAllowTestTraffic hook. The functions can run validation tests.
	// If a validation test fails, a deployment rollback is triggered. If the validation tests succeed, the next hook in
	// the deployment lifecycle, BeforeAllowTraffic, is triggered.
	//
	// If a test listener is not specified, the deployment will proceed to routing the production listener to the 'green' ECS task set
	// and will skip the AfterAllowTestTraffic hook.
