Beyond Certification: Real Kubernetes Skills


I created this course not just to help you pass the CKA certification exam.

While practicing CKA questions can get you certified, true confidence in working with Kubernetes requires more.

My goal is to equip you with the skills of a real Kubernetes administrator, someone who understands all the critical nuances of the platform.

I deployed my first Kubernetes cluster in 2015 when Google launched its GKE service. Since then, I've worked on multiple Kubernetes implementations.

One thing I’ve learned is that understanding Kubernetes' core components, resources, storage options, secrets management, real-world workflows, and best practices makes a real difference in handling real-world projects.

In this course, I’ve shared the knowledge needed to grasp these core concepts and laid a foundation for further research and deeper learning.

You can also ask questions in our dedicated CKA exam Discord channel or community forum. Our certified Kubernetes experts, with real-world production experience, are here to help!

I continually update this course based on user feedback, adding lessons that will help learners not only in their daily work but also in job interviews. You’ll receive an email notification every time a new lesson is added.
