OpenShift For Beginners: 30+ Hands-On labs You Must Perform | Step-by-Step

In this blog, I have covered the Step-By-Step Activity Guides with 30+ Hands-on Labs of OpenShift Certified Specialist training program that you must perform to learn this course.

Topic’s we will cover:

• What is OpenShift?
• List of the Hands-on Labs
• 8-week Learning Path for OpenShift

What is OpenShift?

OpenShift is a platform from RedHat/IBM to run containerised applications. Under the hood, OpenShift is powered by an open-source Kubernetes engine.

Also, you can think of OpenShift as “Kubernetes” branded by Red Hat with some extra bells and whistles. PaaS (Platform as a Service) built on top of Docker and Kubernetes allows to build, test, deploy, manage, and run container-based applications on the cloud.

If you are a beginner, then check our blog on OpenShift- What, Why, and How?
