Seeking Guidance on Learning Podman: How Do I Get Started?
Asked by
TechieGiraffe47
I've been told to deploy my upcoming project using Podman instead of Docker due to security concerns about root access. I'm open to using new tools, but I'm feeling a bit lost on where to begin. The documentation seems pretty limited and doesn't provide the depth I need, especially when it comes to Quadlets. The top Google results just lead me to a thread, Podman Desktop, or even less informative Quadlet docs. Is there really not much out there? Am I expected to rely on tutorials from tech influencers to learn through trial and error?

What are you specifically looking to do? I've found that the official docs have answered my needs pretty well in the past. If you're confused about Quadlets or translating your Docker setup, maybe start there and ask targeted questions?

I got into Podman mainly for rootless containers, and honestly, I chose it over Docker Desktop because I didn’t want to deal with licensing fees. That was enough for me!

Podman is super user-friendly! I think the docs are quite helpful personally, but if you're looking for something very specific like managing multiple files with Quadlets or understanding systemd service calls, I get the frustration. The documentation could use a little more depth.

Honestly, your infra team should get with the times; rootless Docker has been around for years! While Podman is a good choice—especially for Red Hat environments—most of the solid documentation is found in Red Hat's resources. You might want to check out this link on Quadlets: [Red Hat Documentation](https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/8/html/building_running_and_managing_containers/assembly_porting-containers-to-systemd-using-podman_building-running-and-managing-containers).

If fear of root access is the issue, remember that Docker can also run as a non-root user. Getting the hang of Podman isn't too bad. Focus on grasping the main concept of a pod, and then just search for the commands or steps that you typically use with Docker—most of them translate directly to Podman. It seems like nowadays, everyone wants things to be handed to them on a silver platter instead of digging in themselves.
EasyGoingKoala: Exactly! There's a lot of resources if you're willing to do a little digging. Just don't expect everything to be laid out in a single guide.
