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

I use distro packages. In the rare case something isn’t packaged yet, I package it myself. And for the isolation, systemd services can do most of the things docker can if you need (check systemd-analyze security).

For just hosting services that can be done instead with normal system services, docker makes your setup a lot more complex (especially on the networking side), for little if any gain. Unless I need to spin up something multiple times temporarily on demand or something has a hard dependency on it, I’m not going to bother with it anymore.
