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 just downloaded Podman Desktop and am playing with this. Almost all videos and tutorials out there are for Docker but I'm going to watch those but actually use Podman instead to learn.

Both?

Are you writing your resume? Same answer.

Do you selfhost stuff on bare metal? I feel like most projects provide containers as their officially supported packages.

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.

No, I use an operating system.

Not sure why all the down votes without any explanation.

I too don't use docker for my services. I run Plex on my Arch install via the provided AUR package. 🤷‍♂️ Nobody told me I needed to do otherwise, with docker or anything else. Not sure why that would be better in any way. It could hardly be more performant? And it's as simple as enabling the service and forgetting about it.

People love to hate on people who don't care for containers.

Also, I'm guessing that nobody here actually knows what it means to run code on bare metal.
