Problems with cifs volume

[RichardSchulz52]

I used the proposed compose file and just changed the volume to a cifs mounted folder.

The container start up and a repository folder and settings.cfg file are created in the volume.

Everything works fine when I use the default volume. I can rule out trouble with the cifs setup because i use it for every volume.

Hey @RichardSchulz52, looks like the uid 33 is not allowed to write the volume.

Since your cifs volumes work with other images, can you check as which uid the images are running and with which uid they access/write the volume?

Can you please share your docker-compose.yaml?

[RichardSchulz52]

That was my first thought too, but i do not understand the user rights in a cifs context well enough.

This is the used compose file:

services:
  otterwiki:
    image: redimp/otterwiki:2
    restart: unless-stopped
    ports:
      - 8080:80
    volumes:
      - otterwiki:/app-data
      
volumes:
  otterwiki:
    driver_opts:
      type: cifs
      o: "username=XXX,password=XXX"
      device: "\\\\XXXX\\docker_persist\\otterwiki\\otterwiki"

My other containers do not have a special uid config so its 0:0 by default

[redimp]

The process trying to write the repository is running as uid=33. First try: Set the file_mode and dir_mode to 0777:

...
volumes:
  otterwiki:
    driver_opts:
      type: cifs
      o: "username=XXX,password=XXX,file_mode=0777,dir_mode=0777"
      device: "\\\\XXXX\\docker_persist\\otterwiki\\otterwiki"

[RichardSchulz52]

The same error occurs if I add file mode and dir mode. I don't know if the error is on the server side of the cifs. To mount the remote dir UI use login credentials of a privileged user. This works for every setup so far. It also works with Windows, Mac and Android. Thats why I belive the error to be on the mount dir.

[redimp]

Sounds like an error in the mount. 🤔 Can you check if there was any file or directory created by a previous try? Maybe change the path to:

device: "\\\\XXXX\\docker_persist\\otterwiki\\otterwiki2"
