Necesariamente – Cómo configurar un servidor dedicado en Docker

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

Edificio

docker build . -t necesse-server

Pruebas

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:

versión: '3.7'
services:
necesse-server:
Reanudar: unless-stopped 
build: .
puertos:
- "14159:14159"
volumes:
- tipo: bind
source: /srv/docker/necesse-config/
target: /home/necesse/.config/Necesse/
command: ["-mundo", "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 credentials for an account that 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

docker run -d --env STEAM_USER=<ASteamAccountWhichOwnsNecesse> --env STEAM_PASSWORD=<SteamPassword> --env MOD_1=<modId> --env MOD_2=<modId> --mount type=bind,source=</a/directory/on/your/harddrive>,target=/home/necesse/.config/Necesse/ necesse-server -world <worldname>

in a docker-compose.yml:

versión: '3.7'
services:
necesse-server:
Reanudar: unless-stopped 
build: .
puertos:
- "14159:14159"
volumes:
- tipo: bind
source: /srv/docker/necesse-config/
target: /home/necesse/.config/Necesse/
command: ["-mundo", "myworldname"]
ambiente:
STEAM_USER: ASteamAccountWhichOwnsNecesse
STEAM_PASSWORD: SteamPassword
