Thanks for the great content, I have an open question - How does the ClusterIp decide which replica to forward the request to? Is it always random? can we change it to a different algorithm?
this is one of the rare moments (it's the second one for now!) i get to appreciate what a gift having free internet access is. your videos are simply amazing and i can't thank you enough for what you're doing!
Nana Nana Nana!!!! This is what my mind yells at me whenever a devops related works assigned to my team. Tried out various blogs & other videos, but the clarity on your video is just awesome! Really love your way of making things simpler to get goood understanding
i paid a lot of money to take a course at my local college institute to learn kubernetes, and the instructor didn't teach any of this. I learned a lot from this video than i did taking the course. This video is a gem in kubernetes services. My course instructor spent one class in networking but was dry and boring, nothing in the class about nodeport, cluster ip, load balancer, how pods work, how node works, nothing. This video explained everything in an easy understandable way.
Not sure who are the people who disliked this video but this is the best explanation for Kubernetes Service that you can find - maybe even better than the official documentation.
So I have been working as the lead guy on our team for converting our cloud deployment from Docker Swarm to K8s for a while now. I have taken courses and have even put this stuff into practice but just now finally got a clear understanding of all of the innerworkings of node port vs load balancer. You were able to get me over that hump in 20 mins when a three day course couldnt. Bravo to you.
@@rahulsingh-iq4gd you mean to say how front end pod communicates with backend pod ? If yes, you can either use a service url that is internal or gateway url (nginx/ application gateway)
"ClusterIp service type selector will look for pods that matches ALL labels, not just one" - the key to my issues running my app locally in kubernetes with minikube. Thank you!
I am so lucky that I watched your full playlist first, before any other kinds of stuff. You have imprinted the concepts with a wonderful depiction in my mind, forever.
For So many days, I had a doubt on Cluster IP. Today I got the clear picture on Cluster IP and Node Port. Thank you Nana You are my new Kubernetes Guru.
I'm Brazilian and I'm starting to study Kubernetes because of work, and the only video I could understand was this one even though it was in another language. I'm happy to know that my English is good and that it really pays off to study English for the technology market. And congratulations on the video explaining the ball show!
I've been configuring my cluster following other tutorials and lectures with I having half-baked understanding and some fiddling to get things work. And these clusterPort, nodePort, servicePort, targetPort gibberish have have me Googling all over and are driving me nuts. At nowhere else do I obtain a state of clarify that is the experience I obtained from watching this video. Just wow. This video may not be meant for a complete newbie to try to get things to work, but it does give me an overarching overview and understanding of how things work after I have some basic understanding. It is godsent. Thank you so much Nana.
I've been semi-exposed to Kubernetes and its concepts for 5+ years now and was still plenty confused on many of the concepts. This video is by far the simplest explanation of these concepts that I've come across. Well done!
this video came in time , I was creating a microservice and needed to access from outside but not been public on the internet, I found the sol in your explaination , Thanks a lot Nana for this awsome effort
Nana, k8s services is an area I've really struggled to understand for the last 2 years and now I finally get it - especially with all the various ports. Thank you for such a comprehensive video with such clear pictures and examples.
I had a transparent view of the services now...I worked on these but didnt understand the background of all....the way you described that really make sense
Thank you for this explanation… I am network engineer who works on Cisco aci piece but this helps me understand how end to end traffic flows exactly inside cluster till application
Very excellent video. I usually don't subscribe to tech junkies: I just watch the videos, scramble for the almost indecipherable information and move on. But your information pour is so clear and crisp so I need more. Subscribed!
Thanks for finally making Kubernetes and IaC make sense to me. It's always just been a jumble of 'stuff' and the BIG PICTURE with a drill down really helps.
I usually don't comment on videos at all, but I feel the need to give thanks to you Nana. Great video with great, precise explanations. You're helping out the community a lot. Keep it up!
I have rabbitmq and many time thought how to test mq service from outside of cluster and the same time inside. Every time i used port-forward manually. Now all became clear, thx, Nana:)
What a superb explanation Nana !! All your videos have an excellent content and the way you teach makes it very easy to understand. Thanks a ton !! Keep going ....
Nana that''s so awesome .Such an amazing way to explain these concepts and makes it so simple for us to understand.Absolutely love it .Much love and thanks
Wow, i tried couple of other long videos on the same topic and left confused. I see this vid and i'm like, was it so simple! Well its rather your approach...explanation with graphics is the perfect approach to simply any complex topic. Amazing teacher you are!
Very nice presentation, very clear. I confused with ClusterIP, NodePort and LB for a long time even after reading quite a lot document until I watch this video. Thank you !
Fantastic explaination, God has gifted you with tons of patience -:) to explain slowly and in crisp clear manner. Thank you very much, am sure lot of people like me will benefit with this knowledge.
Your ability to isolate individual ideas, then clearly connect the concept is amazing. Have you ever thought about turning kubernetes concepts into mmo characters, and concepts? As I am learning k8s, there are so many things to know and understand. It would be cool if there were exercises to level up your own character in an open source gamified cluster. Think like DnD, or Gauntlet, where anyone can make a singular exercise of a variable scale. Heal this pod, open a door (ingress), look ahead with commands. It something to think about. Regardless, your videos are absolute gold. I feel like I am able to understand every concept you cover because of how well you are able to draw the lines.

I am chinese,UNIX/HA/STORAGE admin in canada, your video is great! your video is better than any training center in china!!
It's really amazing 🙏
Thanks a ton Nana. This video has helped me understand the concept more clearly and clear up confusions I had.
How many service endpoints or objects of each type can be present in a k8s cluster? Can a pod be part of multiple service endpoints?
this is one of the rare moments (it's the second one for now!) i get to appreciate what a gift having free internet access is. your videos are simply amazing and i can't thank you enough for what you're doing!
3 year later and still relevant today. Thank you Nan, you really do spend time elaborating
and explaining each part in an easy understandable way.
Nana Nana Nana!!!!

Nobody can explain Kubernetes better than you! Even a child could understand it. Thanks for sharing such wonderful stuffs.
Thanks Ritesh, that's a great feedback :)
Agreed...thank you Nana
I do agree, but child must have @Ritesh age 😄

How the pod communicate with backend pod ??

I don't remember watching a technical video with such joy.
It was truly incredible and wonderful. I love it!
Please never stop!
Thank you so much! I'm happy to hear such positive feedback 😊
Thank you. Was setting up ingress as nodeport, but also nginx as node port. This and your ingress video cleared up this mess. Life is good.

Ive just started learning much more on devops and sre and subbed. these videos are great at explaining in my opinion.
It was very clear to understand. Every piece of it is well explained.
Best Explaination in the topic I have seen including answers to what opens ports and who will it be accessible to. Also historical context - nyce! ;)
