This issue tracks cgroupsv2 support in docker.

Fedora 31 switched to cgroupsv2, and docker doesn't support that (yet).

Status on latest fedora-31 image: "docker" command and docker.service are provided by moby-engine, but cockpit.service fails to start up immediately . dnf install docker just brings back moby-engine. moby-engine is a dependency of kubernetes, so it's already on the current images.

We could run check-docker and check-kubernetes with explicitly switching to cgroupsv1 for these tests. The bugzilla says that this is still a supported configuration option.

This is how to do it:

grub2-editenv - set "$(grub2-editenv list | grep kernelopts) systemd.unified_cgroup_hierarchy=0"
reboot

Obsolete now, we stopped shipping cockpit-docker in Fedora ≥ 31.
