Hacker’s Guide to Installing OpenShift Container Platform 3.11
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

Redesign of Crunchtools Post Tags
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

Learning Container Engines by Demo
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. Many people have tackled this subject before – Liz Rice has a great talk where she builds a container engine from scratch. I loved
Hardware 1.0 vs. Hardware 2.0
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

So, What Does a Container Engine Really Do Anyway?
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.
