Podman 4.2.0

I love this, but one challenge I've found is podman kube play had issues with named volumes and `keep-id`. Hopefully those are fixed in this release. I guess I'll find out shortly.

Does anyone have experience “migrating” from docker to podman on a somewhat large scale? I am starting a new job soon in a DevOps role where the devs use both podman and docker and although the resulting images are the same, using two tools where one would suffice does not seem optimal.

For context, it is a medium-sized (~40 devs) commodities trading company running some hundred applications in azure k8s but considering moving to on-prem k8s.

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 just processes" philosophical perspective and more "linux tech" focus of the team - i.e. cgroups v2 exists, lets use it. I would like to see some minor UI stuff such as compressing buildah stage output like docker buildx does but it's understandable why that isn't there (yet?).

I think my only remaining quibble is getting true remote addresses when using rootless networking.

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 software, that they'll choose the modern approach.
