proton

Docker image for hosting dedicated servers that run on Proton. This uses Ubuntu as a base image and installs SteamCMD, GloriousEggroll's Proton build, and rcon-cli. Use this as a base image and write your own script to be called by CMD to start/manage your game server. You must set the build argument GAME_APPID to the Steam AppID of the game you wish to host. By default, the container will be run as a non-root user named steam and the game will be installed to /opt/game - this is set through build arguments USER and GAME_PATH.
