volume subpath of compose file is not honored #2017

Open janusn opened 2 months ago

janusn commented 2 months ago

Describe the bug

For containers created with compose, the volume subpath is not honored when recreating the container.

e.g. for the following compose.yaml:

---
services:
  homeassistant:
    image: linuxserver/homeassistant:latest
    container_name: homeassistant
    network_mode: host
    environment:
      - PUID=1017
      - PGID=1017
      - TZ=Europe/London
    volumes:
      - "/etc/localtime:/etc/localtime:ro"
      - "./config:/config:rw"
      - type: volume
        source: cctv
        target: /config/nest
        volume:
          subpath: ha/nest
    restart: unless-stopped

volumes:
  cctv:
    name: homeassistant_cctv
    driver: local
    driver_opts:
      type: cifs
      o: "addr=10.2.3.4,\
        username=user,\
        password=password,\
        file_mode=0660,\
        dir_mode=0770,\
        uid=1017,\
        gid=1017,\
        rw,\
        vers=3.0,\
        auto,\
        noserverino"
      device: "//10.2.3.4/cctv"

When watchertower pulled a new image and restart the container, the directory /config/nest in the container is mapped to smb://10.2.3.4/cctv instead of smb://10.2.3.4/cctv/ha/nest.

Steps to reproduce

  1. create a container based on the above compose.yaml file
  2. wait for watchtower update the image
  3. check the the volume inside the container.

Expected behavior

The subpath argument is honored by the updated container.

I am also experiencing this issue. I originally was not sure if it was docker or portainer issue originally, but it seems to only occur to containers that are being updated with watchtower.

example sonarr compose.yml:

services:
  sonarr:
    container_name: sonarr
    image: ghcr.io/linuxserver/sonarr
    restart: unless-stopped
    environment:
      - PUID=3002
      - PGID=3001
      - TZ=America/New_York
    ports:
      - 8989:8989
    volumes:
      - /mnt/data/sonarr/config/:/config
      - type: volume
        source: truenas-download
        target: /downloads
        volume:
          subpath: deluge
          nocopy: true
      - type: volume
        source: truenas-media
        target: /tv
        volume:
          subpath: tv-shows
          nocopy: true

volumes:
  truenas-download:
    external: true
    name: truenas-download
  truenas-media:
    external: true
    name: truenas-media

Named volumes were created using:

docker volume create \
  --driver local \
  --opt type=cifs \
  --opt device=//truenas.local/download \
  --opt o=addr=truenas.local,username=REDACTED,password=REDACTED,vers=3.0,uid=3002,gid=3001 \
  truenas-download

docker volume create \
  --driver local \
  --opt type=cifs \
  --opt device=//truenas.local/media \
  --opt o=addr=truenas.local,username=REDACTED,password=REDACTED,vers=3.0,uid=3002,gid=3001 \
  truenas-media
Docker volume inspect output `docker volume inspect truenas-download` ```JSON [ { "CreatedAt": "2024-09-01T01:09:29-04:00", "Driver": "local", "Labels": null, "Mountpoint": "/var/lib/docker/volumes/truenas-download/_data", "Name": "truenas-download", "Options": { "device": "//truenas.local/download", "o": "addr=truenas.local,username=REDACTED,password=REDACTED,vers=3.0,uid=3002,gid=3001", "type": "cifs" }, "Scope": "local" } ] ``` `docker volume inspect truenas-media` ```JSON [ { "CreatedAt": "2024-09-01T01:09:29-04:00", "Driver": "local", "Labels": null, "Mountpoint": "/var/lib/docker/volumes/truenas-media/_data", "Name": "truenas-media", "Options": { "device": "//truenas.local/media", "o": "addr=truenas.local,username=REDACTED,password=REDACTED,vers=3.0,uid=3002,gid=3001", "type": "cifs" }, "Scope": "local" } ] ```

As stated above, when watchtower pulls an updated image and re-creates containers, it does not honor the subpath option specified in the compose file. Redeploying the stack in portainer is enough to update the containers back to their original condition. One interesting thing is that docker inspect sonarr does not show any difference to the Mounts section with or without the subpath option specified.
