What is Garry's Mod?

Garry's Mod, a sandbox game developed by Facepunch Studios and published by Valve in 2006, offers players an open world to manipulate objects without set objectives. Additional game modes like Trouble in Terrorist Town and Prop Hunt, created by other developers as mods, can be added through platforms like the Steam Workshop. This Docker image contains the dedicated server of the game.

How to use this image

Setting up game server

Running a Garry's Mod dedicated server

1. Run using a bind mount for data persistence on container recreation. Replace the following fields before executing the command:

$ mkdir -p $(pwd)/gm-data
$ chmod 777 $(pwd)/gm-data # Makes sure the directory is writeable by the unprivileged container user
$ docker run -d --net=host \
    -v $(pwd)/gm-data:/home/steam/gm-dedicated/ \
    --name=gm-dedicated jcivitell/garrysmod

The container will automatically update the game on startup, so if there is a game update just restart the container.
