NetworkLoadBalancedFargateService to support listener other than tcp80 #4793

@pahud

Description

@pahud

At this moment NetworkLoadBalancedFargateService is extending NetworkLoadBalancedServiceBase, which only support listener on tcp80.

this.listener = this.loadBalancer.addListener('PublicListener', { port: 80 });

Please support different port other than 80.

Use Case

For some TCP application running on Fargate behind NLB, it's very common to listen on port other than 80.

Proposed Solution

Add a listenerPort property for NetworkLoadBalancedServiceBaseProps.

export interface NetworkLoadBalancedServiceBaseProps {
/**
* The name of the cluster that hosts the service.
*
* If a cluster is specified, the vpc construct should be omitted. Alternatively, you can omit both cluster and vpc.
* @default - create a new cluster; if both cluster and vpc are omitted, a new VPC will be created for you.
*/
readonly cluster?: ICluster;
/**
* The VPC where the container instances will be launched or the elastic network interfaces (ENIs) will be deployed.
*
* If a vpc is specified, the cluster construct should be omitted. Alternatively, you can omit both vpc and cluster.
* @default - uses the VPC defined in the cluster or creates a new VPC.
*/
readonly vpc?: IVpc;
/**
* The properties required to create a new task definition. One of taskImageOptions or taskDefinition must be specified.
*
* @default - none
*/
readonly taskImageOptions?: NetworkLoadBalancedTaskImageOptions;
/**
* Determines whether the Load Balancer will be internet-facing.
*
* @default true
*/
readonly publicLoadBalancer?: boolean;
/**
* The desired number of instantiations of the task definition to keep running on the service.
*
* @default 1
*/
readonly desiredCount?: number;
/**
* The domain name for the service, e.g. "api.example.com."
*
* @default - No domain name.
*/
readonly domainName?: string;
/**
* The Route53 hosted zone for the domain, e.g. "example.com."
*
* @default - No Route53 hosted domain zone.
*/
readonly domainZone?: IHostedZone;
/**
* The name of the service.
*
* @default - CloudFormation-generated name.
*/
readonly serviceName?: string;
/**
* The period of time, in seconds, that the Amazon ECS service scheduler ignores unhealthy
* Elastic Load Balancing target health checks after a task has first started.
*
* @default - defaults to 60 seconds if at least one load balancer is in-use and it is not already set
*/
readonly healthCheckGracePeriod?: cdk.Duration;
/**
* The network load balancer that will serve traffic to the service.
*
* [disable-awslint:ref-via-interface]
*
* @default - a new load balancer will be created.
*/
readonly loadBalancer?: NetworkLoadBalancer;
/**
* Specifies whether to propagate the tags from the task definition or the service to the tasks in the service.
* Tags can only be propagated to the tasks within the service during service creation.
*
* @default - none
*/
readonly propagateTags?: PropagatedTagSource;
/**
* Specifies whether to enable Amazon ECS managed tags for the tasks within the service. For more information, see
* [Tagging Your Amazon ECS Resources](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-using-tags.html)
*
* @default false
*/
readonly enableECSManagedTags?: boolean;
/**
* The options for configuring an Amazon ECS service to use service discovery.
*
* @default - AWS Cloud Map service discovery is not enabled.
*/
readonly cloudMapOptions?: CloudMapOptions;
