However, Amazon EFS file system support entered general availability with Amazon ECS-optimized AMI version `20200319` with container agent version 1.38.0, which contained the Amazon EFS access point and IAM authorization features. We recommend that you use Amazon ECS-optimized AMI version `20200319` or later to use these features. For more information, see [Amazon ECS-optimized Linux AMIs](./ecs-optimized_AMI.html).

-  * When using Amazon EFS volumes for tasks that are hosted on Fargate, Fargate creates a supervisor container that's responsible for managing the Amazon EFS volume. The supervisor container uses a small amount of the task's memory and CPU. The supervisor container is visible when querying the task metadata version 4 endpoint. Additionally, it is visible in CloudWatch Container Insights as the container name `aws-fargate-supervisor`.
