No Unit-Test, one Integration Test ist present. The similar compontent s3 deploy-action has no unit-test (didnt found it), so I oriented there. Please give me feedback when required.

I have tested the integration test in my private AWS Account, and it worked.

Notes:

• I did not implement toCodePipelineInvokeAction (on service?) as service and repository is required, as I didnt figured out an easy api for this. Need feedback if this is required.
• The default IAM rules are maybe too open (ecs:* for *), I oriented on the default AWS CodePipeline Role: https://docs.aws.amazon.com/codepipeline/latest/userguide/how-to-custom-role.html
• Not included in the component, but in the integration-test: sts:AssumeRole and iam:PassRole for * - same reason as point before. The following would be ideal, but I didnt figured out how to construct this with cdk:

              - Resource: "*"
                Effect: Allow
                Action:
                  - iam:PassRole
                Condition:
                  StringEqualsIfExists:
                    iam:PassedToService:
                      - ec2.amazonaws.com
                      - ecs-tasks.amazonaws.com

Fixes #1386
