I mean I know several people who run their infra with podman. But it's for personal things, I don't know if there is any level of usage at the enterprise level.

podman has underpinned our Kubernetes distribution, OpenShift, since 4.0 was released in 2019. OpenShift is a $1B+ USD business for us (https://www.newsobserver.com/news/business/article271678707....). You can search and see a sample of who uses it for Enterprise level business.

OpenShift Container Platform uses CRI-O as the container engine and runC or crun as the container runtime. Podman is only directly used for the openshift-installer, but as a container management tool uses the same underlying runtimes. This means they share the same long tenure in production when it comes to using runc. Is that what you meant?

The answer is a little bit more nuanced, as the defaults differ. Podman uses crun by default: https://podman.io/docs/installation#:~:text=crun%20%2F%20run.... For OpenShift the use of crun is available as a Technology Preview: https://www.redhat.com/en/blog/whats-new-in-red-hat-openshif... since 4.12. The default for 4.14 is still runC.

Notwithstanding, Podman is gaining a lot of momentum, especially now with Podman Desktop. Disclaimer: I work for Red Hat on the Podman Machine and OpenShift Local/CRC teams to provide integration with Podman Desktop aiming at developer usecases

Not enterprise level, but I made a choice of deploying podman at $job rather than docker for a few reasons.

I'll chime in to say that I have started deploying podman over Docker where it's frictionless at $job as well. I'd say half (or more) of my new container deploys are podman.

At home I use only podman because my tinkering doesn't affect anyone but me.

Podman Desktop sees a lot of increased use in the last few months and the PM has spoken with many of our 'customers' about the future and how they are using podman.
