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
I don't know what this Madam puts in her paid courses when all the valuable knowledge is already given away in her youtube videos for free. This channel is enriching my knowledge from 3 years, Safe to say she is my personal trainer at this point. Thank you mam.
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 !!!
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.
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 👏🏻
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!
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.
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!
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!
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!!
The clarity in this video is phenomenal. Thanks a lot for helping us all out with Kubernetes - very high skill ceiling to begin to learn, but you broke it down perfectly.
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 Nana, as a Junior DevOps engineer being tasked with learning Kubernetes quickly this really helped me get a grasp on it. I'll be delving deeper into this as will need to administer this for my company. Your crash course helped a lot in giving me the fundamentals. - having the lab and your docker image ready to use is helpful - your icons over the yaml templates helped reiterating what service, deployments etc is helpful - your well thought out structure of the video was helpful. Theory, use cases, demo
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 !
Wish all tech RU-vidrs 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.
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 😀
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.
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
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.
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.
NaNaaaaa u r saving my life. Ur videos are really helping me a lot for my job purpose. Awesome content. Not everybody can explain clearly. I have searched so many videos for Kubernetes, EKS, and ECS ... but I only understood those concepts from your videos..... God bless you and your family, Nana... Love from India 😘😀😍🙌✌️
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
I recently watched this training video on RU-vid and I was really impressed. The instructor was clear and concise, and he did a great job of explaining the different features of the Kubernetes . Overall, I thought this was a great training video and I would definitely recommend it to anyone who is interested in learning how to use Kubernetes Crash Course for Absolute Beginners. Pros: Clear and concise instructor Lots of practical examples Well-organized and easy to follow Cons:
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.
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
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!
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) 😂😂
Thank you very much for these videos, as a non-english speaker I appreciate your voice, tone and clarity, I have been able to understand everything without repeating it. It is incredible how all doubts are cleared up and with the practical part and it helped me to establish my local development environment
I'm disappointed with the time I spent trying to understand and implement Docker. I just made the best use of 2 hours of my life with the two Docker and Docker-Compose classes. Incredible. Tks Nana!
Bohemia eh ? tak díky za to. Very helpful video, will be eagerly digesting the others very soon. One suggestion (not to be rude), but a plosive or other type low pass filter on the audio channel. I had to pull my headphones off a couple times because it sounded like someone was coming up behind me. pozdravy z kanady o/
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.
Such a smooth learning experience. I just wanted to check, and found myself watching the whole video like the watching the last episode of Game of Thrones!
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.
The instructor Nana is super talented at speaking clearly and concisely which is a tremendous benefit to anyone looking to learn technical subject materials. If she were not so talented on this subject then I can see her as a super model. Thank you for this!
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!
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! 🙌💯🙏🏼
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.
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!
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?
Hi Nana, in this 1 hr session, you have provided very crisp information of k8s and demo, before this course I was clueless with kubernetes but now after watching this, I feel bit confident. Thanks for your efforts and very well designed course.
Hi Nana! Thanks for this video, really helpful. I followed your tutorial and faced an issue: I can't reach the webapp from the local machine with your configuration but can reach it from the machine itself (127.0.0.1:3000) or from the docker VM (192.168.X.Y:30100) or from the local machine after passing the command "minikube. service webapp-service --url" which gives me a random port to try. Everything looks like your settings on the video minikube kubectl -- get svc NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE kubernetes ClusterIP 10.96.0.1 443/TCP 28h mongo-service ClusterIP 10.96.39.71 27017/TCP 22m webapp-service NodePort 10.105.2.222 3000:30100/TCP 22m minikube kubectl -- get node -o wide NAME STATUS ROLES AGE VERSION INTERNAL-IP EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME minikube Ready control-plane 28h v1.24.3 192.168.49.2 Ubuntu 20.04.4 LTS 5.10.104-linuxkit docker://20.10.17 Do you have any clue?
I am on windows 10 and this command gives me the URL: "minikube service --url" where you can get the service name by doing kubectl get all. Then for for the app service name for me for the example was 'webapp-service'. Thus the command to use for this example is minikube service webapp-service --url
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.
I love your teaching style! giving a nice overview, and then starting with a very basic example and slowly adding on and explaining each feature by starting with the problem they solve makes understanding kubernetes so intuitive. I can tell you must put a lot of time into structuring the video to make it so compact yet effective. loved it!
