Weird permission issues because PUID/PGID is being ignored I think?

[mbround18]

Discussed in #786

I am running into weird permission issues if I try to pass in the PUID and PGID Environment variables to the container. It appears as though the PUID is being passed properly but the PGID might not be.

Here is my compose file:

version: "3"
services:
  valheim:
    image: mbround18/valheim:latest
    restart: always
    container_name: valheim
    stop_signal: SIGINT
    ports:
      - 2456:2456/udp
      - 2457:2457/udp
      - 2458:2458/udp
    environment:
      PORT: 2456
      NAME: ""
      WORLD: ""
      PASSWORD: ""
      TZ: "America/New_York"
      PUBLIC: 1
      AUTO_UPDATE: 1
      AUTO_UPDATE_SCHEDULE: "0 1 * * *"
      AUTO_BACKUP: 1
      AUTO_BACKUP_SCHEDULE: "*/15 * * * *"
      AUTO_BACKUP_REMOVE_OLD: 1
      AUTO_BACKUP_DAYS_TO_LIVE: 3
      AUTO_BACKUP_ON_UPDATE: 1
      AUTO_BACKUP_ON_SHUTDOWN: 1
      UPDATE_ON_STARTUP: 0
      PUID: "1001"
      PGID: "1001"
    volumes:
      - ./valheim/saves:/home/steam/.config/unity3d/IronGate/Valheim
      - ./valheim/server:/home/steam/valheim
      - ./valheim/backups:/home/steam/backups

My server has my personal user at 1000:1000 and this valheim user at 1001:1001

if I do docker-compose up (with or without --build) it starts to launch but I get lots of permission denied errors:

If I run this, with my valheim (1001:1001) user without any PUID or PGID args it creates a structure where the directory and files are all 1000:1000 aka my regular user account owns them. BUT IT WORKS*. I just want all of these files/directories and everything to be owned by my valheim 'service' account that I created for additional security.

I think the steam user inside the container is running at 1000:1000 by default and it seems to not like it if you pass the variables.

What am I doing wrong? I am sure its something super dumb on my end, but maybe its a bug?

For what its worth I search for an answer, saw this #18 and #23 but nothing in there seemed to point me in the right direction other than it seems like it was fixed years ago?

@wesgould id like to close this issue out, are you able to test mbround18/valheim:sha-f25b81a for your use case?

[wesgould]

Hey @mbround18 yes, I was able to test and it worked. I saw your follow up in the discussion thread as well, so I will be trying that "extend the container" option as well.
