How to mount EFS inside a docker container?

I am trying to mount EFS inside a docker container running on EC2 server. EFS mount in EC2 is working fine with,

sudo mount -t nfs4 -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport <efs-address>:/ efs

But when tried in docker container, it is giving error 'mount.nfs4: Operation not permitted'. Please let me know how to achieve this.

If you are using Amazon Linux (ECS Optimized), or have installed the Amazon ECS Volume Plugin you can do the same as @masseyb and @yellowsoar with:

docker volume create efs \
    --driver amazon-ecs-volume-plugin \
    # example "fs-1234:/" or "fs-1234:/html" to bind an inner folder
    --opt device=fs-arn:/ \
    --opt o= \
    --opt type=efs

or within a Docker Compose:

volumes:
  efs:
    driver: amazon-ecs-volume-plugin
    driver_opts:
      device: "fs-arn:/" # example "fs-1234:/" or "fs-1234:/html" to bind an inner folder
      o: ""
      type: efs

For docker-compose file:

💡Please replace aws_efs_host to your EFS DNS name.

volumes:
  volume_name:
    driver: local
    driver_opts:
      type: nfs
      o: addr=aws_efs_host,rw,nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport
      device: ":/"

You can create a docker volume using EFS:

docker volume create \
    --driver local \
    --opt type=nfs \
    --opt o=addr=10.0.0.50,rw,nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2 \
    --opt device=:/ efs

Then mount the volume docker run --rm -it -v efs:/mnt ubuntu:18.04.
