Docker has not built support for cgroups v2 - which has been available in linux for 3 years. https://github.com/opencontainers/runc/issues/654

in order to force this issue, Fedora has made cgroups v2 as default and mandatory in the new upcoming Fedora 31 causing docker to fail to run. https://github.com/docker/for-linux/issues/665

Podman (and other docker equivalents) have supported cgroups v2 for years.

I suspect that k8s will move away from docker to recommending one of the alternatives pretty soon.

Out of curiousity, have you seen anywhere using CRI-O/podman in production in place of Docker anywhere?

GKE already provides containerd for new deployments.
