Thanks Dusty.
What's the latest on including Podman in Fedora CoreOS?
podman is in Fedora CoreOS and is a replacement for the docker CLI.
Axel, have you looked into podman at all? It is a drop-in replacement for docker in most
cases, and should be flexible enough to do what you what, but we might need to ask on
podman mailing list for anything specifics.
Since Axel is running kubernetes he'll most likely want to consider
the GPU support in CRI-O (alternative K8s runtime), rather than podman
as an alternative to docker. We might have some CRI-O experts that
could weigh in on the GPU support there.

Docker runtime as from version 19.03.
