[slurm-users] container on slurm cluster

[Hermann Schwärzler]

Hi GHui,

fyi: I am not a podman-expert so my questions might be stupid. :-)

 From what you told us so far you are running the podman-command as 
non-root but you are root inside the container, right?

What is the output of "podman info | grep root" in your case?

How are you submitting a job from inside the container?
You have to have Slurm and munge installed and correctly configured 
inside the container for that, right?
Why are you using such a container in the first place?

Regards,
Hermann
