I tried podman for multiple times. Normal testing & sandox stuff just works and you really can do alias docker=podman. But ass soon as you add nertworking me broke for me. And for me it is really just a tool and I need my tools working. So I switched back.
Recently I did the GitLab Runner migration for a company and switched to rootless docker. Works perfectly, all devs did not notice all there runs now use rootless docker and buildkit for builds. All thanks to rootless kit. No podman problems, more secure and no workflow change needed
