Amazon_ECS_5

ECS Cluster should not have running container instances with unconnected agents

Description

The Amazon ECS container agent associates container instances to your cluster and tells Docker when to start, stop, and query the containers you have specified to run. If the agent is unable to access the service, the container instance is not able to operate as a member of your ECS cluster.
