Your registry can retrieve your images Due to the highly dynamic nature of the task deployments, users cant rely only on policies that point to specific tasks. However, those methods may not provide the desired level of security because environment variables can be shared with any linked container, read by any process running on the same Amazon EC2 instance, and preserved in intermediate layers of an image and visible via the Docker inspect command or ECS API call. The user permissions can be scoped at the cluster level all the way down to as granular as a single container inside a specific ECS task. Here is your chance to import all your business logic code from host machine into the docker container image. DaemonSet will let us do that.
