The Ultimate Kubernetes Administrator Course

Everything you need to master the Certified Kubernetes Administrator (CKA) exam in one comprehensive and practical course!

Become a K8s Administrator — Go from Zero to Hero!

Kubernetes (K8s) is the most popular platform for container orchestration. More and more companies are adopting it. So, the need for IT professionals who know Kubernetes is higher than ever and increasing every year.

This means, if you invest time in learning K8s and getting certified as a K8s administrator, you will have an incredible advantage and a head start in your IT career!

K8s is an open-source system for automating deployment and management of containerized applications.

I wanted to create the most valuable K8s Administrator course 🚀 As usual you can expect complex topics explained in a simple way, animations to help you understand the concepts better and lots of hands-on demos!

By the end of this course, you'll be able to

Compared to other courses about K8s...

...you learn everything hands-on! Instead of "just" explaining the concepts theoretically, you work with step by step demos.

So, you'll have done everything a Kubernetes Administrator has to do with real life examples on virtual machines instead of working in a sandbox environment.

Starting from installing Kubernetes to configuring and administering it!
