About

LinuxGSM is a command-line tool for quick, simple deployment and management of Linux dedicated game servers. This container image builds weekly and is available on Docker Hub as well as GitHub Container Registry.

Images are built for linux/amd64 only and use gameservermanagers/steamcmd as their base.

Building

There is a single Dockerfile; choose the Ubuntu release with the UBUNTU_VERSION build argument (defaults to the current LTS):

docker build --build-arg UBUNTU_VERSION=24.04 -t linuxgsm:ubuntu-24.04 .

The versions that get built are listed in ubuntu-versions.json. A weekly workflow checks for a new Ubuntu LTS. Once the matching steamcmd base image exists, and the image builds and passes a smoke test, it opens a pull request to add the new version.

Running a single command

Arguments after the image name are passed to the game server script, which runs them and exits with their status. This is useful for one-off tasks on a stopped server, such as details, validate or backup:

docker run --rm -v /path/to/data:/data -e GAMESERVER=gmodserver gameservermanagers/linuxgsm details

Do not run a command this way against a volume that a running container is using. The two containers cannot see each other, so commands such as update or stop would not work safely. For a running server, use docker exec instead (here the container is named gmodserver):

docker exec -it --user linuxgsm gmodserver ./gmodserver details
