Preface

After working at Red Hat for a few years, in late 2014 I was assigned to a newly-established team called Cloud Enablement. Our task was to bring the company’s range of middleware products to the OpenShift Container Platform, which was then being developed on top of Kubernetes. At that time, Kubernetes was still in its infancy—version 1.0 hadn’t even been released yet.

Our team had to get to know the ins and outs of Kubernetes quickly to set a proper direction for our software and take advantage of everything Kubernetes had to offer. When faced with a problem, it was hard for us to tell if we were doing things wrong or merely hitting one of the early Kubernetes bugs.

Both Kubernetes and my understanding of it have come a long way since then. When I first started using it, most people hadn’t even heard of Kubernetes. Now, virtually every software engineer knows about it, and it has become one of the fastest-growing and most-widely-adopted ways of running applications in both the cloud and on-premises datacenters.
