Hi there!

I’m trying to set up two services (through docker) both of which use port 8080 by default. However I am wanting these to services to sit behind a VPN using Gluetun. I added both of the ports I want to use to the compose file, but this just leads to only one of the services working as the other one will say “port already in use”. How can I strictly tell these services what port they shall use in the compose file?

This is how I did it so far;

docker-compose.yml

---
version: '3'
services:
  vpn:
   image: qmcgaw/gluetun:latest
   container_name: vpn
   restart: unless-stopped
   cap_add:
    - NET_ADMIN
   environment:
      - VPN_SERVICE_PROVIDER=custom
      - VPN_TYPE=wireguard
      - VPN_ENDPOINT_IP=####
      - VPN_ENDPOINT_PORT=####
      - WIREGUARD_PUBLIC_KEY=####
      - WIREGUARD_PRIVATE_KEY=####
      - WIREGUARD_PRESHARED_KEY=####
      - WIREGUARD_ADDRESSES=####
   devices:
    - /dev/net/tun:/dev/net/tun
   ports:
    - '8080:8080'
    #VPN
    - 8888:8888/tcp
    - 8388:8388/tcp
    - 8388:8388/udp
    - 8000:8000/tcp
    - 8584:8584
    - 8585:8585
   volumes:
    - /docker/appdata/gluetun:/gluetun
  sabnzbd:
    image: lscr.io/linuxserver/sabnzbd:latest
    container_name: sabnzbd
	network_mode: container:vpn
    volumes:
      - /docker/appdata/sabnzbd/data:/config
    restart: unless-stopped
  qbittorrent:  
    container_name: qbittorrent  
    image: linuxserver/qbittorrent:latest
    restart: unless-stopped
    network_mode: container:vpn  
    volumes:  
     - /docker/appdata/qbitorrent:/config

    On my phone so I haven’t got the access to give you a good example.

    You see in your compose file in your original post you have ‘8080:8080’ under ports?

    You should be able to add another line, the left hand side of the colon exposing a different port like so

    …
ports: 
    - ‘8080:8080’
    - ‘9090:9090’ 
…

    then one service you can access on port 8080 and the other you access on 9090

    then under each service you want to expose you add the other port mappings

    qtorrent:
    ports: 
        - 8080:8080

sabnzb:
    ports: 
        - 9090:8080

    edit - so you should end up with the vpn container exposing 8080 which points to the service exposing 8080 which maps to application listening on 8080

    and the same for 9090 -> 9090 -> 8080

      when I do this I get the error message that the ports are already in use by the vpn container :|

      but I thought the containers had to have “network_mode: container:vpn”, in order to strictly only be able to communicate through the VPN.
