Hello!
It would be nice if there was a general use SteamCMD container for running game server. From what I can tell it should be possible to just have a docker container with the SteamCMD code in it that when passed the correct Steam game ID for the server (such as Satisfactory, the server steam game ID is: 1690800) it will download and run the server.
On Unraid there are a few templates for such, but it would be nice to have a general image that the user can just put the Steam game ID and ports required in as environment variable or the like.
