Docker Alternative: Podman on Linux (linuxblog.io)

Let’s walk through what Podman is and how to use it as a Docker alternative on Linux. Expect a straightforward guide on installing Podman, running containers with it, and understanding the basics.

podman missed the chance to grow, by making it very difficult to configure and use it. The way quadlets work is just such a struggle, if you have been using compose for years. And no, I don’t want to use podman compose, as I can just use rootless docker instead.

Learning new things is hard, sure, but quadlets are not that complex. Take a few hours to sit down and read through the manual or a tutorial, and you'll find they're easier to maintain, write, and deploy.

Hot take: Docker compose is poorly designed, and very little thought went into the deployment side. It only 'won' because it was there first, and bad habits are tough to break.

Fully agree with the compose part, as it has some weird shit in it, too. I gave podman with quadlets many chances and after a while, I always switched back to docker for some reason

Docker Compose works great with Podman.

It supposedly does. But why should I use podman then?

[–] witten@lemmy.world 2 points 3 weeks ago

The main reasons for me are security, reliability, and one less daemon. But you do you.

Native system packages and more features as well.

Okay, now I am curious. Can you please explain what exactly you mean? Like, what do you mean by “Native system packages”? And what features would you miss with docker? Thanks!

Sure! Docker CE needs you to add their own repo for deb or RPM based distros. Podman is available on all of the big distros main repos.

The biggest feature to me is this one https://docs.podman.io/en/latest/markdown/podman-kube.1.html

Podman and docker are good getting started with container steps (nerdctl is also awesome), but just a starting point with k8s being the goal for almost every service and job deployment to me.
