What is SteamCMD?
The Steam Console Client or SteamCMD is a command-line version of the Steam client. Its primary use is to install and update various dedicated servers available on Steam using a command-line interface. It works with games that use the SteamPipe content system. All games have been migrated from the deprecated HLDSUpdateTool to SteamCMD. This image can be used as a base image for Steam-based dedicated servers (Source: developer.valvesoftware.com).
How to use this image
Whilst it's recommended to use this image as a base image of other game servers, you can also run it in an interactive shell using the following command:
$ docker run -it --name=steamcmd cm2network/steamcmd bash
$ ./steamcmd.sh +force_install_dir /home/steam/squad-dedicated +login anonymous +app_update 403240 +quitThis can prove useful if you are just looking to test a certain game server installation.
Running with named volumes:
$ docker volume create steamcmd_login_volume # Optional: Location of login session
$ docker volume create steamcmd_volume # Optional: Location of SteamCMD installation
$ docker run -it \
-v "steamcmd_login_volume:/home/steam/Steam" \
-v "steamcmd_volume:/home/steam/steamcmd" \
cm2network/steamcmd bashThis setup is necessary if you have to download a non-anonymous appID or upload a steampipe build. For an example check out: https://hub.docker.com/r/cm2network/steampipe/
Configuration
This image includes the nano text editor for convenience.
The steamcmd.sh can be found in the following directory: /home/steam/steamcmd

Image Variants
The steamcmd images come in two flavors, each designed for a specific use case.
steamcmd:latest
This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used as the base to build other images off of. This image's default user is steam, any command executed in a higher layer Dockerfile will therefor be executed as that user.
steamcmd:root
This is a specialized image. This image's default user is root. If you need to install additional packages for you game server and do not want to create excess layers, then this is the right choice.
Note: Running the steamcmd.sh as root will fail because the owner is the user steam, either swap the active user using su steam or use chown to change the ownership of the directory.
