Can Podman actually replace Docker for Running Linux Containers? | Into the Terminal 110

The hands on labs are super cool. Kudos Red Hat.

(Points and laughs at Nate) Hey, don’t blame me, just following Scott! 😄 Thank you so much gents! This is a great video for me to point new podman users towards to give them a simple starting point. 👍

Support for the newer features in Podman like quadlets, and the older version of systemd in RHEL8 means to get the best experience from Podman you need to be on recent versions of RHEL9

Does this podman name inspired from K8s actually😅?

[@scottmcbrien6535]

I don't think so. My recollection is that we wanted to make groups of containers and manage them. Since we were already grouping containers into pods, this became the organizing concept of Kubernetes as well.

Unless you are building from source, podman is difficult to get started with latest version. The package version from distros are quite far from latest. Imagine looking at a podman 5.0 tutorial but your distro gave you 4.3 or something. It is quite annoying. Second, podman desktop works only on fedora I think, there doesn't seem to be any configuration for you to change the distro. (last I tried on wsl)

[@scottmcbrien6535]

The content we covered in the show has worked in Podman for a while, so you shouldn't need Podman 5 to find success. That said, Podman 5 is available on RHEL9.4 as well as Fedora. Ubuntu 24.04 uses 4.9.3. So maybe this is a distro choice? RHEL does pretty well at keeping updated stuff while the releases are in "Full Support" lifecycle phase, which right now is RHEL9. RHEL8 just went to "Maintenance Support" so it should largely stop getting updates except for Critical and Important security errata. I use Podman Desktop on my Mac, so it's not just Fedora; though I've not looked at whether or not it's available (and works well) on Windows.

Can you do an episode about docker ?

[@scottmcbrien6535]

But why, when you can replace Docker with Podman? And, in fact, install the podman-docker utility so you can even run 'docker' commands (which will keep your automation tooling intact or provide a 'compatibility layer' for people with long command memories).

@@scottmcbrien6535 ok, will play with it at home

[@crissdell]

​@@scottmcbrien6535 what about docker compose?
