Configuring AWS ECS to have access to AWS EFS

If you would like to persist data from your ECS containers, i.e. hosting databases like MySQL or MongoDB with Docker, you need to ensure that you can mount the data directory of the database in the container to volume that's not going to dissappear when your container or worse yet, the EC2 instance that hosts your containers, is restarted or scaled up or down for any reason.
