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
In the VPN service you just expose the port you want and map it to the listener port on the service
vpn: ports: - 5000:8080 - 6000:8080
where you have
servicea listening on 8080 and serviceB on 8080 but exposed on 5000 and 6000 in the VPN service
for example
sorry im still quite new to this… do u have an example of another compose file that does this? Not sure where I put what.
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: - 9090:8080edit - 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
but I thought the containers had to have "network_mode: container:vpn", in order to strictly only be able to communicate through the VPN.
When I am home Ill get an example from my setup 👍
mercii :)
when I do this I get the error message that the ports are already in use by the vpn container :|
