Certified Kubernetes Administrator 2026 (Udemy.com)
Master Course to prepare for Certified Kubernetes Administrator certification.
Created by: Zeal Vora
Last updated July 2026
Our take
Based on the ratings of 3,670 students, a sample of their written reviews and the syllabus, as the course stood in July 2026. No course pays to be reviewed.
This is Zeal Vora's prep course for the Certified Kubernetes Administrator exam. The syllabus shows eight domain sections, plus an intro, exercises and a short exam prep block, across 177 lectures and about 25.7 hours. It assumes you already understand Docker. It also works as a general Kubernetes foundation, and one reviewer calls it a good general overview to follow with serious exam practice. About 33,600 students have enrolled since 2019, and it was last updated in July 2026.
Students praise the teaching most. They describe simple language, theory followed by a hands-on example, and enthusiasm that keeps them watching. The complaints are specific. One reviewer says the ingress section is dated, because the nginx ingress controller is no longer maintained and Gateway API is now recommended. Others want more depth on architecture and TLS, one cloud provider instead of hopping between several, and a built-in lab. One reader found the AWS comparisons confusing without AWS experience, and another says the terminal clears too fast to read.
The ratings are strong. Of 3,670 reviews, 2,236 are five stars and 1,164 are four. But the four-star comments carry a warning. The CKA is a hands-on exam, and one reviewer says the course falls short at simulating it. Treat this as the concepts course, then add timed practice elsewhere. A reviewer also notes that a fair number of lessons are duplicated in the author's CKAD course.
Pros
- Zeal explains complex ideas in simple language, with a practical demo after each theory lesson
- Sections follow the CKA domains, from core concepts through troubleshooting
- Rated 4.7 across 3,670 reviews, and most sampled reviews give four or five stars
- Covers networking, security, storage and cluster installation in about 25.7 hours
Cons
- Ingress section is dated: reviewers flag the no longer maintained nginx ingress controller
- Exam prep is three lectures and 35 minutes, with no quizzes or timed mock exams listed
- Cloud setup moves between providers, and some reviewers hit DigitalOcean costs or limits
Zeal is a fantastic trainer. The way he explains complex concepts in simple language makes it more easy to understand and the enthusiasm to learn more only grows with each video
Listed as intermediate, but it only asks for Docker basics, so Kubernetes newcomers can start here.
What you will learn
- Strong Fundamentals of Kubernetes

Some topics I would have liked to have a little more granular information on to better understand the underlying mechanism - I can’t think of exactly what, but a pattern would be saying something doesn’t / won’t work without why it won’t work or what would happen if you tried. One thing was you mention says to to configure things and that we will need to know it for the exam, but there are no practical examples of what or why you might observe something in a cluster and how that would tell you that you need to update a particular setting, just how to do it.
By Daniel Cerman on 1/11/2026
This is a worthwhile course which I am watching all the way through. A fair number of lessons are duplicated between this and his CKAD course. Zeal is very knowledgeable and I like his lesson pattern of following exposition of theory with practical examples. I also appreciate his recommendation to save Kubernetes control plane hosting costs by using DigitalOcean. There is room for improvement. Zeal clears the terminal screen very quickly after typing commands, making it hard to read what he entered without pausing the video, which can be distracting.

Thanks Zeal for such comprehensive but in the same time focused on essentials course. I was initially following the course just for an update on Kubernetes universe. But now I will redo it and I really try the CKA exam as I''m convinced the course provides all the prerequisites for a successful attempt . :)
By Shashank Singh on 7/16/2025
Very good course by Zeal again. Perfect blend of theory and practicals. Best part is that it is very recently updated for most of the videos, you dont feel like attending legacy lectures. Emphasis on learning to write the manifest files is not there though. Support for queries can be better, no response at all from anyone :(
By Janette Fournier on 7/10/2025
I found this course to be extremely well explained. The instructor breaks down the concepts in a clear and engaging way, which really motivated me to move through the material faster than I expected. It kept me focused and made learning enjoyable. Only one suggestion: it would be very helpful to have access to the presentation slides in a version with a white background. The current dark background looks great on screen but is a bit challenging when printing and taking handwritten notes. A printer-friendly version would definitely enhance the learning experience even more. Thank you for a great course!
By Harleen Kaur on 4/6/2025
Overall a good course! It would have been better if there were practice videos as well. Also, I really enjoyed your Terraform course where you helped us navigate the documentation. Since navigating documentation plays a major role in the CKA exam, it would have been more helpful if you had taken commands directly from the official docs instead of your GitHub.

This course by Zeal Vora is very simple and easy to understand. I followed the course to the T and passed my CKA certification in Aug 2023. I highly recommend this course as the concepts have been explained very clearly and there are quite a few practical examples, along with solutions that one can practice to master their hands-on
By Santosh Surve on 8/12/2023
Zeel explained all the concepts in a straightforward way and was easy to understand. This course will not only help to clear the exams but anyone can also clear the interviews. I am looking for your other courses as well like GIT, GITHUB, JENKINS, PYTHON and many more. Thank you so much, Zeel.
By Tendai Musonza on 6/2/2021
Zeal ,you are so amazing ,I am a networking Engineer but i am getting carried away learning container technology .I enjoy practical learning and that is exactly what is unique about your Tutorials. Excellent , i cant resist buying your material because its priceless and the best for me
