In this video I will give you a complete overview of Kubernetes Services:
First I explain shortly what Service component is in Kubernetes and when we need it and then I’ll go through the different Service types:
* ClusterIP Service
* Multi-Port Service
* Headless Service
* NodePort and LoadBalancer Service
I will explain the differences between them and when to use which.
So by the end of the video you’ll have a great understanding of K8s Services and will be able to use them in practice

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?
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!
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 😄
Bhaisahab ye kuch zyada nahi hogaya?
Exactly!
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.
I would love to see a video about all the used subnets (Nodes, Pods/Containers, Services, Ingress, LoadBalancer) and how routing and/or access to them works. I constantly get confused about it (especially when I try to understand it on layer 2)
"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!
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.
Everytime I watch this, I will drop a comment so that it will raise through the algo ranking. Nana deserves it
Thank you, your support means a lot!
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.
Great to hear 😊 Thank you for your positive feedback!
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!
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.
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
That's great, thanks for your comment! :)
This was absolutely fantastic - some of the most complicated concepts explained in a matter of mins.. you are a superstar
You speak what the listener wants! Stunning display of content. Struggling with this concepts from quite a long. Thank You!
Wow really glad to hear 😊 Thanks for your feedback 🙏
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!
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.
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.
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!
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.
How the pod communicate with backend pod ??
@@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)
Excellent tutorail..... I took 50+ pauses to grasp this ocean of knowledge.
Me too ..
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 !
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!
this is as clear as it's gonna get, thank you
This is so much clearer than the majority of the videos that are out there. Excellent job,
Thank you 😊
By far the Best Explanation ever... Thank you Mam...😊
Wow! Never seen such a crisp and easy explanation of k8s concepts. Thank you so much. Please keep making such excellent videos.
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 😊
Thanks and appreciate all the efforts gone into along this video and all other video . Being into test automation - your videos are adding great value and knowledge source for me .
Speechless, Awesome, Marvelous, Excellent, Bingo, I don't have words to say for your teaching style. God bless you and keep it up.
very detailed, logical and understandable piece.
it is not the first video of yours about Kubernetes which I watched and made everything clear for me
Finally... after so many poor effort videos - a clear, honest explanation. Thanks. Thumbs up. Subscribed.
Thank you for Docker and k8s series. I've shared the same with my friends and my colleagues, all of us have been benefited by your content.
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!
Me too. All the best.
Love your Technical videos, you explain things in such a meaningful way. Topics that are difficult to understand you make it easier to grasp them. Thank you for such great explanation.
Thanks very much, very clear explanation of this complex topic! Your video is much easier to understand than the official documentation!
Thanks every much for these videos' its very hard to find something explained so well online.
Great combination of concise language and clear graphics. Helping me get up the k8s learning curve quickly! Great job.
Thank you Simon 😊
It was truly incredible and wonderful. I love it!
Absolutely brilliant explanation and cleared up a lot of things for me, excellent content thanks Nana
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
That's amazing to hear! Thank you so much for your comment 😊
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 🙏
Great insight, best thing was how you linked all the service types with one another. Thanks a lot.
Happy you liked it! :) Thanks Arpan!
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.
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.
Can't thank you enough, the clarity in this video is superb.
I'm not a DevOps enginner, I am a software engineering but passionate about DevOps.
I can surely say that your tutorials are the best out there and real life examples about it. Thank you a lot for these! 🙏
same here :)
I am a great fan of you. Your way of explaining technical stuffs is phenomenal
Absolutely brilliant explanation and cleared up a lot of things for me, excellent content thanks Nana
Nana, thank you for this. I had to learn all these in a hurry to get up to speed on a job and your explanations are the clearest I have come across. Keep the videos coming!
Thanks Nana for clear the concept of service in kubernates!!!
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.
This is the most useful video regarding kubernetes services exposure I've found
What a brilliant, lucid explanation. Top class presentation, thank you!
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:)
So far the best tuto ever made in this world !! thank you so much for this video, it's so clear and very helpful.
Thank you Nana.
Best tutorial I've seen on Kubernetes in a long time - Thanks for the explanation!
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
dude this is fantastic! Best description seen so far. Personally I think the headless description was bit long considering its not a hot topic but I skipped little ahead to the service types and the descriptions and animations are great.
You are the best in this sector. thumbs up
She makes me love my software engineering degree. Her explanatios is clear and precise. Thankyou so making it easier for us.
Well done. One of the best tutorials I’ve seen for a while. Great stuff 👏
I was looking for this topic. Got it. Thanks for posting valuable content. Your videos are so clean and clear. Liked it.
Thanks a lot Ankush, really happy to hear :)
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 ....
The visuals you included really helped me grasp the concepts. Seeing the different components and how they relate to each other made it easier to understand how services fit into the larger Kubernetes ecosystem - thank you @Nana
Love ur videos. It's amazing how u make even the most complex of concepts really simple.
I rarely comment on videos but this one made me want to compliment you! Excellent work! :)
Nana, your videos are fantastic! I've learned a lot from them!
