I have never tested DinD like this on an Alpine host, the error seems to indicate that Docker is not running inside of the container properly. Do other DinD container work properly on an Alpine host? (keep in mind this one is Jammy based as well)

[jon4sweber]

Thanks for the reply!
I do have a jupyterlab, swag, freecad and webtop container running on the same host. The deployment with kasm has worked before. unfortunately i cannot specify if an alpine or kasm update broke it.

When I say DinD container I am referring to stuff like this https://hub.docker.com/_/docker where you run a container with it's own docker runtime in privileged mode.
