Add Steam into the container

[BranislavF]

Hello,

please add Steam (with container workaround to be able to run Proton games).

Thank you

Testers: Please try this and tell me before I add anything to the container.

Example of making Proton in Steam work without Pressure Vessel:

Assuming you have Proton Experimental installed in ~/.local/share/Steam/steamapps/common/Proton - Experimental, create ~/.local/share/Steam/compatibilitytools.d/Proton - Experimental (no runtime) and drop two files there, compatibilitytool.vdf that contains

"compatibilitytools"
{
  "compat_tools"
  {
    "proton_experimental_noruntime"
    {
      "install_path" "."
      "display_name" "Proton Experimental (no runtime)"
      "from_oslist"  "windows"
      "to_oslist"    "linux"
    }
  }
}

and toolmanifest.vdf with

"manifest"
{
  "version" "2"
  "commandline" "'/../../steamapps/common/Proton - Experimental/proton' %verb%"
}

So, after making a first mistake, by creating the folder elsewhere, I can confirm that it is working for me. At least the one game I tried. Using Proton Experimental (no runtime).

By the way, my steam installation folder was in ~/.steam/steam/ directory. Otherwise, it seems to be running ok :)

Thanks

Then, we'll start incorporating when I have time.

I am seeing this error message when I installed Steam the ordinary way.

@BranislavF What is your script/Dockerfile component to incorporate Steam?

[ehfd]

I need someone to dive into this.

Sorry for not replying earlier, but I got the same issue when trying to run the container without elevated privileges. The only workaround I used is to run the container with the --privileged flag. I was able to install steam without any issues. I can help you with some testing, but my knowledge is limited here :)

If so, I cannot install Steam by default as of now, because it cannot be used in a bulk of infrastructure. Something that exposes less than --privileged is --security-opt="seccomp=unconfined". We already know this.

@jsbcannell Hey, I wonder if it might be possible to put some minor bounty on this; I know a friend who can do this pretty easily without opening any privileges but I need to divert his time. This can bring in a lot of new users into your service.
