Docker, Podman and Kubernetes

Migrating from Docker to Podman
If you use Docker, you may or may not have already heard of Podman. It is an alternative container engine, and while I don’t have much knowledge of the details, there are a few reasons why I’m switching:
Podman runs in rootless mode, i.e., it does not need a daemon running as root;
Podman supports new things like cgroupsv2 (coming in Fedora 31);
Docker (actually moby-engine) is difficult to keep up-to-date in Fedora (which may correlate with point 2), and people seem to complain about this (though I’ve not cared too much.) -
