Microk8s on fedora32: cgroup v2 and docker/podman: is there a guide that works?

I’m trying to get microk8s running under fedora 32. It looks like there are 2 issues related to cgroup v2 and docker. I am running podman vs docker. Here’s the error messages:

Thoughts on how to resolve this? I can’t turn off cgroup v2 as it can impact other software.

I’ve found a few links but nothing that allows me to use cgroup v2 and podman together. I’ve not found much else on these topics.

Is there a fedora guide that works?

docker has a stable cgroup v2 version out now probably just upgrade docker to newest version and try again

I can give it a try. I’m hoping to use podman as I’ve used that for awhile.

It seems that the microk8s seems to think docker is installed because there is a docker command (aliased to podman). I’ll try updating everything again.
