Newbie in need of help for backup

You should NOT need to install inside the container. The way it works in plain docker is that you pass the device(s) in to the container and then configure docker to pass in the Nvidia runtimes.

Code:

version: '3'
services:
  jellyfin:
    image: jellyfin/jellyfin
    user: 1000:1000
    runtime: nvidia
    deploy:
      resources:
        reservations:
          devices:
            - capabilities: [gpu]
    network_mode: 'host'
    volumes:
      - /path/to/config:/config
      - /path/to/cache:/cache
      - /path/to/media:/media

I just don't know how to do the same with QNAP.
