Will this eventually make it to RHEL8? Today it's at 4.0.2.

I wouldn't count on it unless you add some extra repo. RHEL releases are historically behind when it comes to software, which is claimed to provide more stability, but often older kernels in RHEL simply will not support the new underlying functionality. I am hopeful that if Podman ever has to make the decision to adapt at a modern pace with new software releases, or constantly try to backport fixes and code for old s…

This is not really correct.

First, some software is updated frequently in RHEL, including podman. RHEL 8 was released in 2019 and it has podman 4.0.2 from earlier this year.

Second, even software that isn't updated often, or at all, in the base system might have newer releases available as modules. For example there are recent versions of Python in RHEL 8, with just the basic runtime so that you can use pip to install more packages.

Third, the RHEL kernel is updated much more than the corresponding LTS releases. The RHEL 8 kernel is closer to 5.15-ish than to the nominal 4.18 release from which it was forked. Pace for backports has slowed down a bit, but there's interest in keeping the kernel up to date because people are running RHEL 9 containers on the RHEL 8 kernel.

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.

Talk about hyperboles. RHEL 8 is from 2018 and has had considerably more updates than Ubuntu 18.04. In fact some packages might even be newer than what is in 20.04.

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.

Personally I followed the rootfs way of installing Fedora to WSL2. It was simple enough and worked fine (including podman). I found no reason to use external tools / scripts / modified distros.

Sadly, some anti-cheat tools in games still refuse to work with WSL2 (they hate Hyper-V, I guess it's been used as attack vector), so back to VMware Player on my personal workstation and using terminal to open Linux shell.

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?

I never used it, but have seen separate "rootless" images many times. Seems like you have to build a separate image for rootless Docker? podman runs regular images under an unprivileged user just fine.

But you have Ubuntu 22.04 if you want newer versions of everything.

Maybe, but plenty of RHEL8 packages still package versions from 10+ years ago.

Given the module streams functionality in the package system in RHEL 8+, it's fairly plausible that it would be introduced using that path.

(Currently, there are 5 'container-tools' module streams listed, with podman versions including 1.0, 1.6, 3.0, 4.0 in stable streams, and 4.0.2 in the rolling stream.)

I don't understand, Ubuntu releases new releases every 6 months? If you want the latest Docker/Linux kernel/whatever, just download the latest Ubuntu. They may be behind on one or two packages but that's it.

Normally you could also grab the releases from the source directly and let the upstream source figure out compatibility for you. However, it seems like the folks over at Podman have discontinued their external repository, so I guess they don't care about bringing new versions to Ubuntu either.

Is anybody able to install it on MacOs with brew? Seems to be broken: „Error: podman: Failed to download resource „podman_bottle_manifest“

I just updated from 4.1 to 4.2 on my M1 using Brew without an issue.

I wonder why Fedora doesn't provide an official WSL package on the Microsoft Store as other distros do. My guess is that they feel that the WSL kernel and init diverge too far from the Fedora kernel and systemd. Can anyone from the Fedora project comment on this?
