Kubernetes and Docker

[swardlincoln]

I would highly recommend the heading be Containers and Pods, or something to that effect, and not Docker. Although Docker has been the most easily recognizable containerization technology, many communities want to build containerization technology that works for the opensource community and not the business model of a popular containerization technology. It seems the Kubernetes community has been moving towards a container runtime interface (CRI) that is not locked into depending on Docker. That's where CRI-O has come into play.

It's the concept behind containers and pods that is important to understand and not necessarily the technology used to deliver those concepts. At least IMHO. These types of technologies will always change.
