Multiple torrent containers through one gluetun with docker compose?

[jogaman]

Hi there,
I have this docker compose file that works excellent with qbtorrent and mullvad (below)

But, how would i add another qbtorrent container to this without port conflicts? If I was to have a bunch of different containers (with various conflicting ports) connected through one single gluetun container, is that possible somehow?

Maybe more of a docker question than gluetun, but hoping someone here would know.

version: "2.1"
services:
   gluetun:
      image: qmcgaw/gluetun
      container_name: gluetun
      cap_add: 
        - NET_ADMIN
      devices: 
        - "/dev/net/tun:/dev/net/tun"
      environment: 
        - VPN_SERVICE_PROVIDER=mullvad
        - VPN_TYPE=wireguard
        - OPENVPN_USER=
        - OPENVPN_PASSWORD=
        - WIREGUARD_PRIVATE_KEY=xxx
        - WIREGUARD_ADDRESSES=10.xx.xx.xx/32
        - SERVER_CITIES=Amsterdam
        - TZ=Amsterdam
        - HTTPPROXY=on
        - HTTPPROXY_USER=xx
        - HTTPPROXY_PASSWORD=xx
      ports: 
        - "8888:8888/tcp"
        - "8388:8388/tcp"
        - "8388:8388/udp"
        - 8080:8080 	#qb
        - 6881:6881		#qb
        - 6881:6881/udp	#qb
      
      volumes: 
        - "/data/gluetun:/gluetun"
        
   qbittorrent:
      image: lscr.io/linuxserver/qbittorrent:latest
      container_name: qbittorrent
      environment:
       - PUID=1000
       - PGID=1000
       - TZ=Europe/London
       - WEBUI_PORT=8080
      volumes:
       - /data/qbtorrent/config:/config
       - /mnt/video/qb/downloads:/downloads
      restart: unless-stopped
        
      network_mode: 'service:gluetun'

To clarify, it looks like I have two options

1. network_mode: 'service... This way I need to be lucky there are no port conflicts, like in this example https://stackoverflow.com/questions/59340558/route-docker-container-traffic-through-a-vpn-container
2. Socks proxy. This way I manually need to make sure for each app that the traffic goes through the proxy

What I'm hoping for is a way to force all traffic of an entire container but still be able to map ports to avoid collisions.

You have to configure the second qbitorrent to listen on another port. Since they're on the same network host (gluetun), they can't listen on the same port. I am not aware of any other solution (which would pretty much depend on docker/lxc changes imo).

I'm confident you can set the qbitorrent port with a bind mounted config file somewhere, and you could open an issue on their repository asking to configure it through an env variable too, to make it easier.

Thanks for getting back about this, you confirm my understanding of my options.
