Podman and CRI-O in RHEL 8 and OpenShift 4

What This is a quick article to pull together the entire picture of Podman and CRI-O with the releases of RHEL 8 and OpenShift Container Platform 4. In a nutshell, you get Podman with RHEL in a single node use case (orchestrate yourself) and CRI-O as part of the highly automated OpenShift 4 software stack.

History Lesson on PaaS People often rewrite history in their minds. They see the way the landscape looks today, forget the chronological order of events, and reconstruct a false model of cause and effect. I am guilty of doing this from time to time. One such history is that of PaaS. The year was 2012,

In Part I: Is Docker Supported in OpenShift 4 and RHEL 8? I explained that the the Docker daemon will not be supported in new Red Hat products, but that Docker images will be. The next question people always ask me is, “Why? I thought you guys love Docker? I’m confused.” There are many reasons

Part I: Is Docker Supported in OpenShift 4 and RHEL 8?

TL;DR: Docker container images are supported in OpenShift 4 and RHEL 8, but the Docker daemon and client are not. Instead, containers will be run with CRI-O in OpenShift 4, and Podman in RHEL 8 – the same images can be used anywhere because of container standards. Cool, if that’s enough information for you and

Testing With Podman – Complete Uninstall/Reinstall

Testing With Podman – Complete Uninstall/Reinstall

Background Sometimes it’s necessary to uninstall completely, and reinstall when testing software. This is something I have been doing with podman on RHEL 7.6 since about 6AM today 🙂 I figured it was worth capturing the instructions I have developed while testing user namespaces and rootless containers. This could make your life easier too. Complete
