Big fan of Podman. Technically every time I have tried to push it into my production workflow I've hit some snags, mostly around networking and some volume stuff but those snags are getting chipped away each release. The last time I did a strong test flight was around 3.X, so probably about time to try again, 4.0 was a big release. I like the integration with systemd and bringing "pods" out of k8. I like the "they're…

You can use podman with buildkit, it's just kind of a pain because you have to do it manually. It is missing some nice to have feature integrations with buildkit. The instructions are fairly clear: https://github.com/moby/buildkit

I was looking at this just last night and the story with Ubuntu is horrible. That's essentially going to be stuck on v3.4 for ten years because it's "a lot of work" to get into that distribution.

You'd think an entity the size of RedHat trying to take the reins from Docker would understand that this is an investment they have to make to make it a first-class replacement.

I also installed it on Windows to see how the WSL engine works but now it conflicts with my existing v3 Podman installation on Ubuntu 20.04 in WSLv2 so I guess I'm out of luck.

Also may be of interest to people here but Podman desktop had a release yesterday. It's pretty primitive and I couldn't get it to work to use my existing auth.json but it's there.

It was a pretty frustrating experience when all I wanted was to be able to "podman login" to a local repository so Jib would pull down base layers correctly.

Wasn't podman mostly C at some point? Did they rewrite it in Go?

I've did a bit of reverse searching. They've used Go all the time[1] [1]( https://github.com/containers/podman/tree/3d0100bb44834d079a... )

They were first to push crun[1], in place of runc, that is your C code in the stack :-)

Red Hat has no official affiliation with Canonical who make Ubuntu.

If you want to test podman you 'll have better luck using an OS from the Fedora ecosystem where Red Hat has affiliations and is actively contributing.

Since you mentioned Windows I 'd suggest trying something like this [1] or this [2]

Disclaimer. I am not using Windows to test above solutions anymore. More than a year ago I used [2] but from a casual look maybe [1] is better now.

Ubuntu has nothing to do with Podman / Redhat. Ubuntu also has a terrible track record of not aligning where it makes sense with other distorts and not properly testing packages - it's just a bit of a flaky distro in general.

Nah, red hat probaby cares very little about that.

Red hat probably cares about delivering the best it can for its users (red hat, centos and fedora users).

Podman probably has no explicit goal of replacing docker, it only has the goal of providing a workstation container management implementation. Which might happen to be an awesome substitute for docker.

Earlier quoted context omitted.

If you want to do a straight migration you can start the socket unit and expose it via the DOCKER_HOST environment variable and use the standard docker tooling or use podman-docker to make it seamless. As long as you make no other changes everything should just work. Where people frequently run into issues is when they want to utilize the rootless feature, and that definitely requires adjustments and work.

Rootless is definitely one of the major selling points for using podman over docker, especially for local development.

Isn't there support for rootless docker these days as well?

You mean not aligning with Red Hat and what they're pushing on everyone else. Ubuntu is on a shorter release cycle compared to Debian so they're usually the first non-Red Hat distro with new stuff. Systemd vs Upstart, Unity vs GNOME (3?), etc.

They try to do new stuff, and there's nothing wrong with that. Not everyone should blindly follow RH's lead. Systemd was objectively shit at the beginning, run by a person who was actively hostile to any feedback he didn't like. There were multiple highly critical bugs whose patches weren't backported ('just update' as if it's that easy with the sprawling beast that is systemd).

> not properly testing packages

What do you mean? I only recall one popular instance of an issue with Ubuntu packages, and it's when they released a major upgrade to Samba because backporting a critical security fix to the previous major version, the one that came with the distro originally, was too hard (in their words), which ended up breaking Samba for a bunch of people.

Ubuntu isn't "flakey". It makes a different tradeoff compared to RHEL - slightly newer version of stuff for slightly less stability. For many orgs that's preferable to obsolete 10 year old versions of most software for amazing stability.
