ECS Blue Green deploy not supported

[joaoricardo000]

A while ago the Blue Green deployment option on ECS services was updated and now is managed by AWS Code Deploy.

If you call a service that was set up with Blue-Green option, that is the ecs deploy output:

Updating service
An error occurred (InvalidParameterException) when calling the UpdateService operation: Unable to update task definition on services with a CODE_DEPLOY deployment controller. Use AWS CodeDeploy to trigger a new deployment.

Looking into the AWS docs for CodeDeploy, it's a whole new set of API calls, using another client (codedeploy not ecs) to start and monitor the deployment process.

I spent some time understanding the environment and the calls, and come up with this hack:

I'll open a PR soon with this code merged with the Actions of ecs-deploy.
