Steam Headless is a Docker container designed to run SteamCMD, Valve's command-line version of the Steam client, in a lightweight and headless environment. It allows users to easily deploy and manage Steam game servers without the need for a graphical user interface, making it ideal for server administrators looking to automate game server updates and maintenance. By leveraging Docker, Steam Headless ensures a consistent and isolated environment, simplifying the setup process across different systems while supporting Steam’s extensive library of dedicated game servers.
The container supports various features such as automatic updates of the SteamCMD client and game servers, configuration through environment variables, and persistence of game server data via mounted volumes. This streamlined approach helps reduce the complexity involved in hosting multiplayer game servers, providing a reliable and efficient solution for self-hosting Steam-based dedicated servers in a containerized environment.
