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.
"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 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!
This was absolutely fantastic - some of the most complicated concepts explained in a matter of mins.. you are a superstar
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!
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!
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 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 😊
Excellent, easily explained step by step everything. Fantastic.
Absolutely brilliant explanation and cleared up a lot of things for me, excellent content thanks Nana
Very well articulated! Learnt a ton by going through this playlist! Thank you!
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! :)
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 .
Excellent tutorail..... I took 50+ pauses to grasp this ocean of knowledge.
Me too ..
What a brilliant, lucid explanation. Top class presentation, thank you!
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
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.
Speechless, Awesome, Marvelous, Excellent, Bingo, I don't have words to say for your teaching style. God bless you and keep it up.
this is as clear as it's gonna get, thank you
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 🙏
Thank you for creating this video, Nana! It is clear and to the point!
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.
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.
Wow! Never seen such a crisp and easy explanation of k8s concepts. Thank you so much. Please keep making such excellent videos.
I am a great fan of you. Your way of explaining technical stuffs is phenomenal
Can't thank you enough, the clarity in this video is superb.
Nana, your videos are fantastic! I've learned a lot from them!
Well done. One of the best tutorials I’ve seen for a while. Great stuff 👏
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!
Best tutorial I've seen on Kubernetes in a long time - Thanks for the explanation!
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.
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)
Great combination of concise language and clear graphics. Helping me get up the k8s learning curve quickly! Great job.
Thank you Simon 😊
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.
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
This is the most useful video regarding kubernetes services exposure I've found
you are just amazing Nana ! you saved me days with this .. brilliant !
Your videos and explanations are EXCELLENT. I especially like the graphics and animations!!!
Thanks Nana for clear the concept of service in kubernates!!!
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 :)
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
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.
Thanks very much, very clear explanation of this complex topic! Your video is much easier to understand than the official documentation!
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.
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.
your diagrams helped to clarify everything. thank u
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 ....
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 so much clearer than the majority of the videos that are out there. Excellent job,
Thank you 😊
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 complex but explained so beautiful. Great thanks !
Very well explained, thanks for putting together this awesome content Nana 🙏
Love ur videos. It's amazing how u make even the most complex of concepts really simple.
Very well explained the whole Service concept! Thank you very much for making such videos.
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 😊
Thank you for these video tutorials - very helpful!
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 !
That was crystal clear, Nana....
Thank you....
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!
Great video, congratulations! Continue with this wonderful and high quality work!
You make it so easy to understand! Thank you!
All my questions and confusion have cleared. Thanks a lot!
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)
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 :)
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!
Great video! Well explained concepts. Thanks for this!
Thanks every much for these videos' its very hard to find something explained so well online.
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.
Awesome explanation. Loved it.
well done, smooth and crystal clear..thank you sooo much
Great explanation, you've given me a better understanding of k8s services. Keep up the good work.
very complex things you explained very easily. thank you so much for your hard work.
Your tutorials are awesome and very helpful! Thanks to share it!
I was looking for a video with this kind of explanation. Thank you for clearing lot of my doubts.
This is one of the best learning platform for learning Kubernetes 👋👋
Great insight, best thing was how you linked all the service types with one another. Thanks a lot.
Happy you liked it! :) Thanks Arpan!
It was very clear to understand. Every piece of it is well explained.
Excellent presentation, clear and concise. Thank you
Thank you Nana, you are gifted no doubt. 👌
This is best video I have seen for k8 services, please please continue the good work. Big fan of you Nana 🎉
This is awesome explanation of service.. thank you so much
It was just wonderful. Thank you! Graphics helped a lot.
Thank you for your positive feedback :)
So much information in this video. These kind of videos are useful for quick learning. Thanks
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:)
Thank you so much for this video. This was very helpful to clear up some confusion I was facing
If teaching is an art, you're an excellent artist
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.
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
Thank for creating such a great content with very simple explanation, I would recommend this video to my colleagues to watch
By far the Best Explanation ever... Thank you Mam...😊
The best video so far which I found to understand services, @Nana you are amazing ! Thank you so much !
It's a wonderful video relevant to K8.
Clears concepts
Cleared all my doubts thank you so much nana 👏
Ive just started learning much more on devops and sre and subbed. these videos are great at explaining in my opinion.
These videos are great!! You explain incredibly. Salutes from Colombia!!
thanks. It was a clear explanation, specially how diff. services work together
Beautiful explanation I have seen multiple videos not single explains in such details and provide the clarity
