Should I learn Docker or Podman? (iusearchlinux.fyi)

Hi, I've been thinking for a few days whether I should learn Docker or Podman. I know that Podman is more FOSS and I like it more in theory, but maybe it's better to start with docker, for which there is a lot more tutorials. On the other hand, maybe it's better to straight up learn podman when I don't know any of the two and not having to change habits later. What do you think? For context, I know how containers works in theory, I know some linux I think well, but I never actually used docker nor podman. In another words: If I want to eventually end up with Podman, is it easier to start with docker and then learn Podman, or start with Podman right away? Thanks in advance

Honestly, if you have never used containers before I would suggest starting with docker as it has more readily accessible beginner walk through and tutorials. From there, you will have a good idea as to switching to podman is the right move for you or not.

Personally, I started with docker and haven’t moved from there since I don’t see a need (yet). I have dozens of services running on docker. I don’t know how heavy of a lift it would be to learn podman but like I said, I don’t feel the need to do so.

Maybe try out both and see which one you like more?

Just to offer the other perspective. I started with podman years ago. I knew very little about containers and I would say it made the learbing curve a lot steeper. Most guides and README's use docker and when things didnt work I had to figure out if it was networking, selinux, rootless, not having the docker daemon, etc... without understanding fully what those things were because I didn't know docker. But when I started running stuff on kubernetes, it was really easy. Pods in podman are isomorphic to kubernetes pods. I think the pain was worth it, but it was definitely not easy at the time. Documentation, guides, and networking have improved since then, so it may not be as big of a deal now
