So you recorded over 3.5 hours of excellent content without any fillers or fluff + posted on youtube without monetizing with adds? Hats off to you!

[toshowmyvideo]

For those of you, who got stuck at 2:13:00 and cannot follow along the course, because there is no kubernetes-dashboard in kubernetes. Just execute '$minikube dashboard' and K8s will generate it for you automatically

[DavidOkwii]

No skipping Ads on this one. The author should properly be compensated for such a great tutorial.

[adimardev]

this is my 4rth day on learning devops and everything started to make sense after watching 3 full videos. docker, jenkins, kubernetes. i'm no longer confuse thanks to these amazing people on youtube puting up amazing works.

[brunoc.]

The problem with this big long video is that I can like it only once! 😁
It's extremely well organised, crystal clear... and free! Thank you so much for your amazing work.

[bikashkanodia]

No other k8s training required after this training. I am lucky to find such channel👍

[nikhilverma]

This 1 big video tutorial is far better than the complete official K8 documentation. Thank you for making this available for free for everyone.

[sandeepunnikrishnan]

I can confidently say that this is probably the best kubernetes tutorial you can find on YouTube

[VictorS]

My full team is watching this. Really good content, happy to support your work.

[rubenk]

I just completed 45 minutes of the course. I knew it is going to be among the best Kubernetes tutorial out there. Thank you for sharing your excellent knowledge on this topic.

[solidwire]

5 other Kubernetes videos washed over the top of me, while Nana's organization & continuous visual aids made learning Kubernetes not only attainable but an enjoyable experience...
I believe a big difference is her knowledge & understanding of the intricacies & their correlation becomes clear with her ability to break down the concepts & infor into easily digestible pieces. Thank you very much!

[SwapnilRandhir-uusb]

My God!! I recently started working on K8 at my workplace. I was so overwhelmed.
But you literally solved all my doubts in a single video!!
Thank you so much!!

[davidyoung]

Just like I've told people that Code Complete is the quickest 1, 000 pages they'll ever read, your tutorial is the quickest 4 hour video I've ever watched. Well structured without diving into too many details out of the gate. Thanks a bunch for putting this together!

[radovanthefoley]

The best tutorial I have ever taken. Structured, easy to go back to, clear examples, keeping it essential, but not trivial. Love it!

[MrAymCFC]

The only 3+ hour video I've ever watched on Youtube, you are an amazing instructor, truly love your content! Many thanks!

[mohanraj]

I usually hate lectures.. but you capture me with the content. Appreciate you for the skills of tutoring. Really good.

[AshokGelal]

After searching for a good Kubernetes tutorial for years, I believe I've finally found the best one! Thanks for a great content and getting directly to the point with the right balance of lecture and demo.

[rubenaster]

Just wow.... no small talk, only facts and knowledge explained in a visual, easily understandable way. Perfect!
