Locally mount AWS EFS using docker-compose
EFS assumes nfs4, so:
version: '3.8'services: postgres: volumes: postgres_data:/var/lib/postgresql/datavolumes: postgres_data: driver_opts: type: "nfs4" o: "addr=xxx.xx.xx.xx,nolock,soft,rw" device: ":/docker/postgres_data"Of course, the referenced nfs-export/path must exist. Swarm will not automatically create non-existing folders.
Make sure to delete any old docker volumes of this faulty kind/name manually (on all swarm nodes!) before recreating the stack:
docker volume rm $(docker volume ls -f name=postgres_data -q)This is important to understand: Docker NFS Volumes are actually only the declaration where to find the data. It does not update when you update your docker-compose.yml, hence you must remove the volume so any new configuration will appear
see output of
docker service ps stack_postgres --no-truncfor more information why volume couldn't be mountet
Also make sure you can mount the nfs-export via mount -t nfs4 ...
