Request: Steam (Headless) on CasaOS

Request: I am using Zima OS on my ZimaCube with an A2000 graphics card. It would be fantastic not only for that specific hardware to run „Steam“ headless.

I found actually two projects which seem to make this possible, although (at least for me) it is a rather complex dockerfile. The goal would be to install all games on my NAS and play the games by using SteamLink, or as with some clients directly from the Steam App (shows link automatically to the remote „server“).

An optional possibility would be „Games on Whales“ GitHub - games-on-whales/gow: A collection of Dockerized games and apps like Steam, Firefox and Retroarch - which uses Moonlight, Sunshine instead of SteamLink.

EDIT: I am aware that a LinuxServer variant exists, although this one is not headless - it uses instead kasm, which is a nightmare for remote launching, plus it does not support currently nvidia graphics cards. (GitHub - linuxserver/docker-steamos: Vanilla Arch modified into SteamOS with web based Desktop access, useful for remote play and lower end games)

Maybe a little late to the party here, but I managed to get Steam-Headless running on ZimaOS, as a custom app (import a docker compose file) so hopefully should work on CasaOS too?
Here’s my compose file, edit to suit your system (passwords/usernames/mounts etc)
I couldn’t get inputs to work in sunshine, so I have it disabled, but I use steam link to connect to it in desktop mode instead. I should also point out I’ve set this up with an nvidia rtx 3060ti, but should pick up whatever card you have if you select it in the setup dialog after importing the file.
Hope this is of help to someone
