Sauerbraten: Cube 2 server via Docker

⁠Accompanying docker-compose.yml

version: '3'

services:
  srv:
    image: captaingeech/cube2srv:latest
    ports:
      - "28785:28785/tcp"
      - "28785:28785/udp"
      - "28786:28786/tcp"
      - "28786:28786/udp"
    volumes:
      - ${PWD}/server-init.cfg:/srv/sauerbraten/server-init.cfg

⁠Usage

Read this blog post⁠ for details, but tl;dr copy server-init.tmpl.cfg to server-init.cfg and make any changes you want, then run:

$ docker-compose build
$ docker-compose up -d

The docker-compose.yml file uses a volume to mount the server-init.cfg file in your current directory into the proper container path, modify as you see fit.

After a couple minutes, your server should show up in the server list in the game. If it doesn't check the logs with docker-compose logs and ensure that your network settings are correct (by default, ports 28785 and 28786 via both TCP and UDP).
