Congratulations! One of the builds has completed. 🍾

You can install the built RPMs by following these steps:

• sudo yum install -y dnf-plugins-core on RHEL 8
• sudo dnf install -y dnf-plugins-core on Fedora
• dnf copr enable packit/sosreport-sos-3373
• And now you can install the packages.

Please note that the RPMs should be used only in a testing environment.

Looks mostly solid so far, just a couple minor comments. I'll get a PR up for the docker change shortly to cover that side of things.

I'm not really happy with the way get_volumes() function is expecting the return, as lxc doesn't necessarily give ids, but names of the volumes. So, at the moment this is giving a list of names of volumes in the default storage pool or the pool from the default profile. This is going to be as good as it goes for the time being.

If this would have a refactor later, we could do with pool + name/id tuple, then that would work better for lxd, but that would mean that docker/podman ones would need to change too. Different concepts of volumes/storage, need to work on understanding how this is used in the wider sos aspect
