Trying out CRC (Code Ready Containers) to run OpenShift 4.x locally

I've been working a bit with Red Hat lately, and one of the products that has intrigued me is their OpenShift Kubernetes platform; it's kind of like Kubernetes, but made to be more palatable and UI-driven... at least that's my initial take after taking it for a spin both using Minishift (which works with OpenShift 3.x), and CRC (which works with OpenShift 4.x).

Because it took me a bit of time to figure out a few details in testing things with OpenShift 4.1 and CRC, I thought I'd write up a blog post detailing my learning process. It might help someone else who wants to get things going locally!

CRC System Requirements

First things first, you need a decent workstation to run OpenShift 4. The minimum requirements are 4 vCPUs, 8 GB RAM, and 35 GB disk space. And even with that, I constantly saw HyperKit (the VM backend CRC uses) consuming 100-200% CPU and 12+ GB of RAM (sheesh!).
