I wish distros would stop making "docker" an alias for "podman", they are not the same thing and breaks all light-k8s implementations.(looking at you redhat)
I've encountered cases where podman CLI does not match Docker, specifically for network creation with IPv6--the commands are different. What are you experiencing?
CLI is not my issue, k3s and kind wont work with podman (or any rootless container for the matter) out of the box, in both you need to do some non-trivial cgroups configuration on the OS to make it work (in k3s this mode is experimental)
