4 command-line tools for Kubernetes: Linux edition

In a previous blog post, I detailed how to install four very useful Kubernetes tools on your macOS or Windows machine. Those tools—kubectl, stern, kubectx, and kubens—are must-haves for the advancing developer, as well as any folks in operations.

In this article, I’ll show how to build an automated integration and continuous delivery pipeline using Jenkins CI/CD and Red Hat OpenShift 4. I will not dive into a lot of details—and there are a lot of details—but we’ll get a good overview. The details will be explained later in this series of blog posts.

Since I recently added a Windows 10 PC to my technology mix, I decided to try to use Windows as my only choice.

I was saddened to learn that the installer, openshift-install, isn’t available for Windows. But, like any developer who won’t be denied; I found a way.
