[CI] Slurm e2e Failing

[asmacdo]

Summary

Slurm test is failing:

/opt/outer/walkthrough-tests.sh: line 45: singularity: command not found

Additional Details

Likely this is caused by an earlier error:

Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=container error was 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error"

Which is probably related to CentOS Linux 7 end of life June 30, 2024 https://www.redhat.com/en/topics/linux/centos-linux-eol

Solution

We likely need to rebuild this container on CentOS 8 or Rocky. https://github.com/giovtorres/docker-centos7-slurm/blob/90fa6b8bf4a557dba9081a6e581c03d0cfe39ef1/Dockerfile#L1

But that repo may not be active, we are already using my fork. https://github.com/asmacdo/docker-centos7-slurm

But good news? Work appears to have begun upstream. https://github.com/giovtorres/slurm-docker

Also development looks good for slurm-docker-cluster which is based on Rocky.

I've asked upstream giovtorres/slurm-docker#1
