Steam image cannot launch steam twice about dockerfiles HOT 7 CLOSED

I'm not sure whether it's related to your problem or not, but you absolutely do not want to run Steam with --privileged=true, ever. When you run a container with --privileged=true, you've stripped away almost all the protections Docker provides against that container doing unexpected (and extremely harmful!) things, so at that point you might as well install Steam on your host instead (and run it as root, because that's the level of privilege you're giving to it).

Running with the simplified docker run -it --rm --device /dev/dri -v /tmp/.X11-unix:/tmp/.X11-unix:ro --ipc host -e DISPLAY tianon/steam bash, and then running steam, letting it download/start, then exiting, then running steam again, it works just fine, so I'm not able to reproduce.

Thank you for looking at this. I really appreciate the helpful information.

On my Debian-Testing host system (intel icelake, linux 5.9.0, gnome/wayland, Docker 1.5), I still reproduce the same failure, using your invocation. My colleague verified that your invocation works properly on his Arch Linux host.

There must be some aspect of my host that is causing this issue. I'm going to install a fresh system to verify that I can get your image working on stock debian testing.

correction. Debian apt reports Docker as:
docker/testing,testing,unstable,unstable,now 1.5-2 all [installed]

Docker reports its version as:
Docker version 19.03.13, build 4484c46

from dockerfiles.

The docker package in APT is definitely not the one you want -- you should do something like dpkg -S dockerd to figure out the package name you have installed (it's likely either docker-ce or docker.io).

I'm just guessing, but I imagine Wayland is probably related -- I have not done any testing of using Wayland (or XWayland) inside containers, and I have no idea what that will require (I use Xfce in X11 for all my Linux "desktop" machines).

It was my mistake to report the docker version. I installed docker.io which reported the 19.03.13 version. I verified that a clean install of debian-testing reproduces the behavior. I also tested with Gnome/X11 and Xfce.

In reading the output of the crashed steam client carefully, I noticed that the last message before the crash is "Proceed to auto login". It turns out that the crash only occurs when I check "Remember my password" when logging in to steam the first time.

To work around the failure:
rm ~/.local/share/Steam/config/config.vdf

from dockerfiles.

I still can't reproduce -- my Steam launches and successfully performs the auto-login both the first and second time. 😞

(I go further and mount a persistent home directory into my Steam containers so even if I recreate the container it will still launch with the same config and auth every time.)

sorry for the frustration. I don't think it is important to root cause this issue, because I can easily work around it. Hopefully this issue will be found in a web search by the next person that encounters a similar crash.
