Get started with OpenShift

Make the Shift

The End Is Nigh

OpenShift and Kubernetes are fantastic pieces of software with an ever-growing feature list. I've barely scratched the surface of how to operate OpenShift here, but I've looked at a simple crossover or two between the command line and the GUI to get you started.

If you are not familiar with image streams (abstractions for referencing Docker images from within OpenShift) because you've only looked at Kubernetes in the past, or you are new to OpenShift, they are well worth trying out, because they offer very valuable and sophisticated functionality [13].

OpenShift has additional security policies and benefits that might be new to you, so pay close attention to those once you have the basics mastered.

Having come this far, I trust that you are now suitably intrigued with OKD and will try running your own applications in a test cluster. I think you'll find OpenShift's upstream parent is a powerful orchestrator well worth investigating.

The Author

Chris Binnie's latest book, Linux Server Security: Hack and Defend, shows how hackers launch sophisticated attacks to compromise servers, steal data, and crack complex passwords, so you can learn how to defend against such attacks. In the book, he also shows you how to make your servers invisible, perform penetration testing, and mitigate unwelcome attacks.
