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
