Kubernetes, also known as K8s, is the most popular platform for container orchestration for automating deployment, scaling, and management of containerized applications.
In this complete Kubernetes Tutorial you will learn everything you need to know to get started with Kubernetes in 1 hour. You will learn all the core concepts, including the main Kubernetes components that you need to learn to work efficiently with Kubernetes. You will learn the syntax and contents of K8s configuration file , which is used to create and configure components in a Kubernetes cluster as well as how to setup a K8s cluster locally. Finally, I will show a hands-on demo project, where you will learn how to deploy a web application with its database into a local Kubernetes cluster. It's a simple but realistic application setup, which can also serve as a blueprint configuration for most common application setups.

Bundle of thanks for the great course, just a query; would you please let us know if there is any pdf format of the context of this video? I'm asking to have a written source to be able to print and study anytime which there is no access to video, thanks in advance :)
Hi Nana, Thank you very much for this short video compared to the other complete K8s guide (3.5 hour video). I must say that these both videos were awesome resources to learn and get hands-on experience.
I followed both the demos in both videos as is but I got the same error each time (with hyperkit and with docker both) - the mongodb deployment gets changed to CrashLoopBackOff error after a few seconds. Error from logs is: uncaught exception: Error: couldn't add user: Error preflighting normalization: U_STRINGPREP_PROHIBITED_ERROR.
I am on Mac and have tried all the options available online but couldn't get it to work. Except, I can get it to work by adding the infinite loop command (command: [ "/bin/bash", "-ce", "tail -f /dev/null" ]) to the deployment yaml, after which the deployment goes to the running state; but, the webapp or mongo-express was not able to load or connect to the endpoint.
Did you run into any similar problems or would you have any pointers for the resolution?
Thanks in advance,
Mayur
Ahh yes
Please, it's difficult to pay for your boot camp from Nigeria. Can you add other payment options, please?
Keep it up!
Nana you make the devops world more accessible and simple to everyone, thanks!
Yes she is the person we would like to get in a team for ever !
Perfect
Joking
You have good playlist :)
she really does, I kickstarted my devops career with her videos, bless her !
Your methodology are just phenomenal. Anyone having no knowledge on Devops or Programming background can even get hands on watching your tutorials. Well done Nana.. Incredible work !!!
Absolutely brilliant 👏
Awesome. Cannot believe how you can take a complicated topic and made it look so logical and easy. I have always believed that building components from ground up is the right way to learn any topic, and you have proved it again. Next step, your full detailed course on K8S. Thanks !
Thank you for the brilliant overview. I want to point out that the presentation of material itself is flawless, super-smooth, well explained, no interruptions and unnecessary info, all this for free. Thank you, Nana, you are doing a wonderful job!
After watching lot of your devops tutorials and learning from them, I feel that you are capable of explaining rocket science in a 2 hour video tutorial 😁..Thank you so much for all the hardwork and dedication 👏🏻
Nana has a GIFT for TEACHING others ... one of the best out there.
Thank you! Your way of explaining the Kubernetes concept was wonderful. I've already tried many courses but your balance between theory and practice is just about right! Again, thank you for putting the time and effort to make such a complex concept so simple!
I can't find the right words to thank you for these tutorials. I have watched a couple of your tutorials and am so grateful that we have people like you to break down these complicated things and explain them to us. Thank you
Thank you so much for this lovely course ! You made Devops easier to understand :)
Thank you Nana for this amazing hands on tutorial, this was extremely helpful, great explanation!
Excellent video Nana, you explain it well! At just the right level, explaining what you're going to do first, creating small knowledge gaps and then filling them all the time, excellent. Thanks!
This is a really thorough crash course and extremely useful. Thanks for making it fun!
Nana: The more I watch your series of videos with K8s, the more competent I am. It's all because:
1) Of the way you structured the course contents
2) The flow of it
3) Precise Contents
4) Visual presentations and explanations to augment and emphasise
5) Delivery style - pace, pitch, volume, etc.
Thank you very much, Nana.
This short course is absolutely fantastic and informative. Thanks for your passion and work, Nana! Keep going!
The best crash course on K8 is well explained, first the concept and then the hands-on. Perfectly presented. After watching this I feel much more confident about the K8 learning path, now I am capable of exploring my own and going deeper. Thanks for the video, Nana.
This is a fantastic video, thank you for the time and effort put into helping us all!!
Honestly I have also watched many videos, tutorials and even udemy on Kubernetes. This is the best organized course from step by step and also not going into too much unnecesary details but not missing the main crucial points. An excellent course presented by Nana and amazing clarity in every step. Thank you so much.
This tutorial was simple to understand and I gained a lot of knowledge and confidence through it. Thanks a lot Nana!
This is the best beginners' course on kubernetes I have ever attended. Thanks Nana!
Nana, for someone like me who did not have the faintest idea of what Kubernetes is, to be able to build confidence in it is remarkable. It speaks volumes of your ability to explain complex topics in a structured, systematic and simple way. Thank you for teaching me.
This was extremely helpful and provided an excellent understanding of all the moving pieces of a Kubernetes cluster!! It cleared up a lot of confusion for me.
Nana, thank you so much for this great tutorial video! The editing, content, and explanations were fantastic. K8s has been a huge question mark for me for years and this tutorial has made me much more comfortable with it!
Thank you Nana for this great session and it is absolutely worth to start directly getting a brief overview about kubernetes in a flawless and to the point. Glad that I watched it in a one go and able recall so much.
this is what I call a GREAT in capitals video. Jeez, this person just put more concepts clear in an 1h than hundreds of hundreds of videos across the whole internet. VERY VERY VERY concise! thanks a bunch! Excellent !
Thank you for such a wonderful crash course!! One of the best and easy explanation 👍
It's been an year since I follow your videos on YT. I will frankly say staring with K8s, I have no regret to keep going on !!
Honestly this is a type of introduction I would see for any framework I am starting with! 1h and I have my basic stack deployed in minicube. Awesome. Thanks Nana!
An extremely superb course that has been watched ever, brief, and key full, all seconds worth, and should not miss even 1 sec! Thank you :)
This is what I was looking for 🙏, thanks one more master piece 👍
I like how she explains the naive way to do it first, then proceeds to explain how to make it better by introducing a new Kubernetes component.
You are amazing Nana. Thanks for making this video. Very crisp covering all the concepts!
Never though learning kubernetes will be this interesting.. You made it all look so easy. Incredible!
Thank you very much, I needed to refresh my memory about kube and this is exactly what I needed.
This course is simply the best!
I have learned in about one hour what I have tried to learn for months.
Thank you very much Nana for sharing your knowledge and the way you teach is priceless 😀
You are the bomb! I have never seen any one that is able to break down something that seems so hard so easily. I will definitely be taking the K8 Administration course. Thanks
Wish all tech RUclipsrs always describe like you, simple, short but comprehensive and not boring! I'm a senior software developer for more than 10 years of experience and I find your videos really great.
Was clueless in a team meeting where there was a demo on how the application was deployed in K8s.
After watching this, I'm confident to work in my new project.
Can understand how much time and effort it requires to create this quality content. Best thing is you gave to all for free. Thank you very much Nana!
Happy to hear and thanks for your appreciation Sathesh!
Thank you for all the amazing free content, checking this now!
Youre a really good instructor. Clear, concise and to the point. Great job!
That must be the most concise and elegant kubernetes quickstart from all youtube. Thank you very much for this material!
This was one of the best crash courses ive seen in a long time. Thank you so much for the time and effort in this video!
Hey Nana, I have watched several videos for kubernetes basics and I was not able to understand how all the K8s components are working. But, After watching your crash course video I got a clear overview and understood each and every basic components. Thank you so much for this video. Keep making such videos.
Her videos are really good. This channel is the reason I have a DevOps career.
What an awesome worthy content! You have made it to understand so easily like none other. I am huge fan of your tech knowledge and concepts for modern technologies. I always refer your videos to understand the basic and advance concepts of technologies I plan to use in the team. Most importantly the practice exercise at the end is the key here. I can readily connect and use all my conceptual knowledge from the video while performing practical exercises. Kudos to your channel and appreciate your hard work. Keep it up !!
Regards
Gaurav
This is way above expectation .. Thanks a ton for explaining every step.. and a fantastic demo.
Thank you Nana! You’re awesome! And the best at turning complex subjects into easy to understand videos and fun projects.
Thanks so much, really appreciate your comment and support! 💙
This is really amazing... took a highly complex topic and not only explained it within 32 minutes, but also have a comprehensive follow along guide, all in about an hour. Seriously, thank you this is fantastic!!
Thanks so much for this great feedback and your support! Really appreciate it!
Great presentation, so clear and concise! This is how technology should be taught! You clearly explained the need for each component in the architecture. Makes it much easier to remember and appreciate each component.
Been doing k8s for a year and this video really brought all my fragmented knowledge together. The best k8s video I've ever watched
The easiest Kubernetes tutorial I have ever seen. Thank you nana for making Kubernetes easy for everyone.
Great tutorial. The way you go through all the components makes it very easy to make notes.
The video could actually be confusing as the video uses the terms "pod" and "container" interchangeably through a large part of the video. Further summarize that a pod is just a wrapper around a container, indicating a 1-1 relationship between pods and containers. In fact, very often you find that a pod would usually contain multiple containers, one each of the main application/service and supporting services.
OMG. This is the best tutorial I have seen on Kubernetes! You are awesome!
So well explained and crisp clear concepts.. Hats off to the Lady !! Her explanation is so good . Deserves an award !
Thanks Nana, one of the best crash courses I ever came across. Really well organized and explained.
Hands down. Best channel for in depth technical knowledge and amazing presentation.
Thank you Nana for an excellent crash course on kuberntes.
Nana, thank you for your contribution for this K8s world. Your material is very helpful. it's easy to understand. You have helped me to connect some many pieces all together. Thank You.
I actually watched a whole video this time! Very well presented and explained, thanks!
Nana, thank you for your great useful videos. The experience we get is priceless for sure. Appreciate what you do! ❤️
Thank you Nataliia, really happy to hear the videos are helpful! :)
Wow.. this is what I was looking for
Step-1: Create diagrams to let the learner picturize it..
Step-2: Now, write code to achieve each diagram...lastly merge the entire things...perfect maam...thank youuuuuu for making this video...
My desired video matches your actual video 🤭 (etcd is youtube here) 😂😂
Glad it was useful for you and thank you for your support 😊
Thank you Nana, it's an amazing video course. So simple to follow. Thank you for the hard work much appreciated!
This was really good. I have been working a little bit with K8s inside GCP, but I was not really sure what was happening most of the time. This makes it really clear!
Thank you so much for this tutorial. On top of it being simply fantastic, I think the best thing you've done is set a starting point for other people to start using k8s. You did an excellent job of this by showing how you're referencing the documentation.
Even though some documentations are fantastic, there's a very small learning curve on how to use them and you've established just that. Thanks for this!!
Thanks Jeff, appreciate your great feedback! :)
This couldn't have come at a better time. Thank you so much! You've truly brought value to my life. Your teaching is clear and effective. After your courses, I feel both ready for a whiteboard interview and ready for the practical skills. This course was an easy buy.
Thank you so much Lucas, really happy to hear such a great feedback! :) 🙏
Fantastic video. The slides at 49:05 were very helpful to understand the key points with not a lot of text in them, good font size and straight to the point. Moreover, the pace was just right and the demonstration code/explanation was on-point. Thank you! 🙌💯🙏🏼
This tutorial is AMAZING. I'm a frontend engineer who would often get stuck in doing these K8s related changes. This 1 hour will save me lot of effort/headache in the future.
You are so damn good at explaining things. Nice job and thank you for sharing!
Such distilled knowledge ! This is by far the cleanest introduction to Kubernetes that I came across. Thanks Nana 💙
thank you so much Rohit! :)
I cannot imagine any more informative and made easy video than this for the beginners. Hands down the best video watched so far on Kubernetes.
it would be nice if you also mentioned limiting resources, which is not included in the example snippets from documentation, but can be quite useful and actually required by some of the kubernetes extensions for vsc
I was following your tutorial on macOS Ventura with Docker Desktop v4.17 and it seems that Docker changed the way it integrates with host's network. What you shown will still work on Linux where Docker adds a new interface to the host OS through which you can communicate with containers. In my case, host OS had no clue how to find the k8s server with the IP returned by `minikube ip`, there was no routing information in the routing table.
What you have to do is to run `minikube service webapp-service` which will create a tunnel to the service via ports published by minikube container and redirect the browser to tunneled port.
Works like a charm. Was having the same issue on Windows 11 docker desktop
Thank you !!! I was like so confused as to why it didn't work in the end - I owe you coffee
Thanks for this info. But it's still not working from my end.
@@taofeekadisa7619 yeah, same issue here
@@himanshujagdale4966 did u find a way around it?
Aaaahhhh!!!! (Screaming jajaja) thanks!!! Big thanks! I needed this from you!!! Today (later) I'm going to watch it immediately. ❤️❤️❤️❤️
I would have never imagined that learning Kubernetes would be this simple and interesting. Thank you so much.
Thank you Nana, well presented. The demo was a bonus. Great work!
Dear Nana Thank you verrrrrrrrrrrrrrrrry much. :)
Can’t wait to get home and watch this. I am sure it is awesome because everything you post is of an incredible quality. Thanks and congrats, Nana! 😀
Happy to hear, thank you Daniel! 😊

I have reviewed many materials about K8S on internet, and I can tell you that your presentation is the best especially for beginners. Contents are organized in clear structure and jargon free. Kudos to you, Nana! Wish you more successes in the New Year!
Thank you! I learn more in this one video than a 5 days ILTP and a 16 hour self-paces course :D You are awesome!!! Subscribed!
This is the best crash course I've ever taken in anything, and I am a self-taugh developer thanks for the great resource.
Thank you Andres, really happy to hear that! :)
Thank you for this great, simple and structured introduction to K8S!
Appreciate your feedback and your support, thank you Renzo!
This was concise clear and exceptionally simplified. Fantastic presentation.
Nana , I salute to your knowledge and understanding of all concepts. Your succint explanations are awesome. You always remain to the point and cover every thing what's required and don't deviate. Lots of Love. Thanks for sharing your knowledge.
Everything about this was perfect. The pace, content, delivery of content and explanations were really well done. Subscribing for more :)
Great Nana ❤
Unbelievably helpful Kubernetes tutorial! I look forward to watching more of your tutorials.
You have really covered a lot of concepts in an hour :). Thank you for sharing this course, it is really informational, learned a lot of concepts as part of this course. Will definitely try your another courses for more details.
absoultely remarkable teaching skills! I've watched many other videos about kubernetes and I wasn't able to quite grasp how it works and how to make it work, until I watched this one
the reason you didn't grasp the idea because it wasn't some cute chic teaching it.
The great teacher again. Btw, I have done the your python course 5.30hrs took me around 2weeks. Its truly awesome. Thank you.
Thank you so much Telia, I appreciate your feedback! 😊
Really liked the pace of this - gave me exactly what I needed to know without all the extra fluff
Learned a lot Nana, thanks for putting this easy to understand guide together!
I have been learning kubernetes from different sources like cloud academy, Linux academy and others for a while now. You did kubernetes explained in such a short and easy way. Wonderfully explained with great flow
Thanks for such a great course .. It made me a permanent subscriber of your courses
That's awesome Shahbaz, really happy to hear that! :)
Your videos really should be included in official K8 documentation. Incredible way of explanation.
Thanks for such an amazing feedback Vedran! And thanks for your support! :)
Simply amazing!!! Complex stuff made real simple!!! Super clear presentation!!! God Bless you!!!
Hi Nana, Thank you so much for offering this course for us to see on You Tube. I am learning so I can get a better job. This is all very new to me. You explain and break technical details very well. Thank you again
Outstanding.
Great tutorial, very well explained.. but Minikube IP is not reachable using Docker Driver (at least on Windows 11) and the Frontend of the webapp is not working (gives a fetch error on JS init function), making the page totally white as the HTML divs remain hidden.
Did you solve this issue?
This is a beautifully done video. Huge thanks to you for producing it!
u nailed it mam, i dont think nobody teaches this complex kubernetes in an hour, love you
Hii Nana, I followed the video till end . @1:10:00 When I ping the minikube's IP along with my nodeport port, it gives nothing. Although pods are running, logs are coming same as coming in your tutorial. Are we really able to access minikube's internal IP?
I used this command -minikube service --url
This command gave me a url and on hitting that url, I can access the application. Can you just clarify my doubt here?
That worked for me too, thanks for sharing.
Thanks, worked for me.
