Does Podman need root?

Rootless podman (running Podman as a non-root user) needs to do some gymnastics to get the same container experience you're familiar with from docker, but without requiring root. When you run rootless podman, it uses a user namespace to map between the user IDs in the container and the user IDs on your host.

How do I remove Podman containers?
