Background My problem, like most technologists, is that I only have a slice of my time to dedicate toward acquiring and maintaining knowledge about any given technology, product, project, tool, platform, etc. Split that with the fact that almost every CIO is preaching that we, as technologists, need to be closer to the business, and

Well, it’s that time of year when you do some clean up – and, that’s what I did while I waited for my OpenShift 3.11 install to finish. I have completely redesigned the WordPress tags to make it way easier to find stuff. This is a selfish endeavor but it should help others too. I
Background I was thinking about naming this article the POWER of Podman, or Podman on Power or Power Man or…but I digress. Confession, it’s been a long time since I played with a POWER system. The last time I did it, it was difficult to get Linux booted up. Now days, with Red Hat Virtualization,

Background So, this morning I had a call with some customers who are using Podman in RHEL 7.6 Beta. We got into a pretty good discussion about what a container engine does.

I’ve seen a lot negative reactions to the terms multi cloud and hybrid cloud. I would argue, that’s because we are framing it wrong. It’s really Hardware 1.0 and Hardware 2.0. In Hardware 1.0 Dell, IBM and HP all tried to sell us fairly similar servers. We typically bought these servers, but we could finance
This past weekend, I had the pleasure of attending the first ever DevConf US 2018, which is the 1st annual, free, Red Hat sponsored technology conference for community project and professional contributors to Free and Open Source technologies at the Boston University in the historic city of Boston, USA. This was a technical conference in

It only takes a couple of quick google searches to realize that people have no idea what a container engine is. That’s understandable because It was a completely new concept back in 2013. Plenty of good people have tried and failed – see WTF is a Container (not deep enough) or What is Docker and why

Container Engines are like wheel bearings, you should be able to replace them when they stop working. Also, you shouldn’t have to care about what brand they are. That’s what the Kubernetes Container Runtime Interface (CRI) aims to solve. CRI defines the API used to talk to container engines and all the major container engines
