docker-compose volumes mount to nas-folder (nfs)

Question

i have a problem with my docker-compose file. i get a error while bringing up the project after docker-compose up. i have a synology nas with an network share. smb and nfs is enabled. from my pc, i have no problems to connect to the share. but starting the container ends with the following error.

the error is:

ERROR: for paperless_webserver_1  Cannot create container for service webserver: failed to mount local volume: mount /volume1/paperless/data:/var/lib/docker/volumes/paperless_data/_data, data: addr=192.168.178.90,nfsvers=4: invalid argument

my docker-compose file:

version: "3.4"

volumes:
  data:
    driver_opts:
      type: nfs
      o: addr=nas-home,nfsvers=4
      device: /volume1/paperless/data
  media:
    driver_opts:

did anybody have an idea?

Maybe it's a bit late, but in case of someone looks for an answer, you are missing a colon at the beginning of the device properties values.

Your configuration should looks like something like that:

volumes:
  data:
    driver_opts:
      type: "nfs"
      o: "addr=nas-home,nfsvers=4"
      device: ":/volume1/paperless/data"
...
