A very generic necesse dedicated server, which updates itself on startup with or without Mods in Docker

Building
docker build . -t necesse-server
Testing
Just test it with interactive mode:
docker run -it necesse-server
But it makes more sense to run it as demon, you also can use all the default start parameters:
docker run -d necesse-server -world mynewworld
Run a Server with No/Self Managed Mods
docker run -d --mount type=bind,source=</a/directory/on/your/harddrive>,target=/home/necesse/.config/Necesse/ -p 14159:14159 necesse-server -world <worldname>
in a docker-compose.yml it would look something like this:
version: '3.7' services: necesse-server: restart: unless-stopped build: . ports: - "14159:14159" volumes: - type: bind source: /srv/docker/necesse-config/ target: /home/necesse/.config/Necesse/ command: ["-world", "myworldname"]
Run a Server with Mods
You can only download Mods from the Steam workshop, if you own the Game, so you need to provide steam credintials for an account which owns the game and is not steam guard protected for running an automated necesse server with mods.
You should provide the password with a docker secret, but for this example it’s plaintext
