1. Create a new group named valheim:

sudo groupadd valheim

2. Add your current user to the valheim group:

sudo usermod -a -G valheim $USER

3. Verify that the group was created and your user was added successfully:

groups $USER

4. Find the group ID (GID) of the valheim group:

getent group valheim

This command will output something like valheim:x:1001:, where 1001 is the GID.

5. Set the permissions for the directories to be group writable, readable, and executable:

sudo chown -R :valheim ./saves ./server ./backups
sudo chmod -R 775 ./saves ./server ./backups

6. Update your docker-compose.yml file to set the PGID:

Open your docker-compose.yml file in a text editor and modify it as follows:

version: "3"
services:
  valheim:
    image: mbround18/valheim:latest
    container_name: valheim
    environment:
      - PGID=1001 # Replace with the actual GID from step 4
    volumes:
      - ./saves:/home/steam/.config/unity3d/IronGate/Valheim
      - ./server:/home/steam/valheim
      - ./backups:/home/steam/backups
    ports:
      - "2456-2458:2456-2458/udp"
    restart: unless-stopped

Replace 1001 with the actual GID you found in step 4. You can also dynamically set the PUID using the id -u command to get your current user ID.

7. Restart your Docker Compose services to apply the changes:

docker-compose down
docker-compose up -d

This will recreate the container with the new PGID settings.
