Aws-cdk: ecs_patterns.ApplicationLoadBalancedFargateService should allow specifying healthCheck path

[jsyrjala]

ecs_patterns.ApplicationLoadBalancedFargateService should have a way to easily specify healtCheck for the loadbalancer.
Currently ApplicationLoadBalancedFargateService creates automatically a healthCheck that points to the root /. I'd like to specify another path.

Use Case

/ is not always suitablte to use as the healthCheck. In my case the correct path would be /health-check.

Proposed Solution

new ecs_patterns.ApplicationLoadBalancedFargateService(stack, 'Web', {
       ...
          // basically same thing as the listener.addTargets() takes
          healthCheck: {
              path: '/index.html',
              protocol: elbv2.Protocol.HTTP,
              port: '' + containerPort,
        },
});

This is a :rocket: Feature Request

I had the same issue. There is a way to change the path by changing the targetGroup of the resulting service:

    service.targetGroup.configureHealthCheck({
      path: healthcheckEndpoint,
    });

@jls-tschanzc Thanks! That works fine.

Maybe there should be some pointers to above in js-docs for ApplicationLoadBalancedFargateService?
