Hi.

My config use a VM with doker and an other VM with NFS packages.

My container works well with this config :

version: '2'

services:
  web:
    image: my_image
    restart: always
    ports:
      - "8888:8000"
    volumes:
      - /media:/srv/media

Inside the folder media I have a new folder uploads with my files created when I upload some images.

if I change for this one (inspired by your example) :

version: '2'

services:
  web:
    image: my_image
    restart: always
    ports:
      - "8888:8000"
    volumes:
      - media:/srv/media

volumes:
  media-files:
    driver: local-persist
    driver_opts:
      mountpoint: /home/bat/volume/media

I have this error :

ERROR: for web  Cannot create container for service web: chown /home/bat/volume/media-files: operation not permitted
ERROR: Encountered errors while bringing up the project.

A folder uploads is created in my host (and NFS server) inside the media folder, the docker volume is created, but the container is not running due to this error.

All folders have chmod 777 for the test.

Thx a lot.

Config :

It definitely seems like it's permissions related. Just because it's 777, I don't think that means you can do a chown. You may need to figure out who your Docker user is (i.e., did you set up a dedicated docker user?) and make sure he (or she) is the owner (or in the group) of the folders.
