My solution for AWS EFS, that works:

1. Create EFS (don't forget to open NFS port 2049 at security group)

2. Install nfs-common package:

   sudo apt-get install -y nfs-common

3. Check if your efs works:

   mkdir efs-test-point
   sudo chmod go+rw efs-test-point

   sudo mount -t nfs -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport [YOUR_EFS_DNS]:/ efs-test-point

   touch efs-test-point/1.txt
   sudo umount efs-test-point/
   ls -la efs-test-point/

   directory must be empty

   sudo mount -t nfs -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport [YOUR_EFS_DNS]:/ efs-test-point

   ls -la efs-test-point/

   file 1.txt must exists

4. Configure docker-compose.yml file:

   services:
     sidekiq:
       volumes:
         - uploads_tmp_efs:/home/application/public/uploads/tmp
     ...
   volumes:
     uploads_tmp_efs:
       driver: local
       driver_opts:
         type: nfs
         o: addr=[YOUR_EFS_DNS],nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2
         device: [YOUR_EFS_DNS]:/
