I want an AWS App Mesh enabled ECS service as a pattern: https://github.com/aws/aws-cdk/issues/4566

[nathanpeck]

I also want a REST API pattern, where multiple services can be mounted onto different paths on an ALB like:

/api/users -> users service
/api/orders -> order service

I'd like to have a resilient scheduled Fargate task as described here: https://cloudonaut.io/resilient-task-scheduling-with-ecs-fargate-cron-scheduled-task/

tldr; it uses Step Functions instead of CloudWatch Rules

Use Case
I'd like to use a pre-existing load balancer listener for multiple ECS services that are differentiated by ALB rules and rule priorities.

Proposed Solution
Add a listener prop to ApplicationLoadBalancedServiceBaseProps which identifies which load balancer listener rules should be added to and an addListenerRule(rule: ApplicationTargetProps) method to ApplicationLoadBalancedEc2Service and ApplicationLoadBalancedFargateService. When addListenerRule() is called, the pattern construct would add ApplicationListenerRules that reference the listener specified in the constructor props.

const loadBalancedEcsService = new ecsPatterns.ApplicationLoadBalancedEc2Service(stack, 'Service', {
  cluster,
  // New prop:
  listener: albListener,
  memoryLimitMiB: 1024,
  taskImageOptions: {
    image: ecs.ContainerImage.fromRegistry('test'),
  },
});

// New method:
loadBalancedEcsService.addListenerRule({
  containerPort: 80,
  hostHeader: "something.example.com",
  priority: 10,
});
