Amazon ECS now supports a state for container instances that can be used to drain a container instance in preparation for maintenance or cluster scale down. The draining state prevents new tasks from being started on the container instance and notifies the service scheduler to move tasks that are running on the instance to other instances in the cluster.
For more information about container instance draining, see the documentation. Please visit our product page for more information about Amazon EC2 Container Service.
