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

[@samboy05]

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?

[@hpibmsun]

I am chinese,UNIX/HA/STORAGE admin in canada, your video is great! your video is better than any training center in china!!

[@jkumar988]

It's really amazing 🙏

[@VR-cr9wn]

Thanks a ton Nana. This video has helped me understand the concept more clearly and clear up confusions I had.

[@VR-cr9wn]

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?

[@RiteshAgarwalGwalior]

Nobody can explain Kubernetes better than you! Even a child could understand it. Thanks for sharing such wonderful stuffs.

[@TechWorldwithNana]

Thanks Ritesh, that's a great feedback :)

[@priyankaroy5627]

Agreed...thank you Nana

[@SoumyaDassrd]

I do agree, but child must have @Ritesh age 😄

[@1improvement28]

Bhaisahab ye kuch zyada nahi hogaya?

[@yanglianglu9098]

Exactly!

[@MaccaBeats]

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!

[@marksheard1210]

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.

[@rmagnum2002]

"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!

[@TheTera110]

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!

[@tmiller673]

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.

[@hareeshhari1601]

You speak what the listener wants! Stunning display of content. Struggling with this concepts from quite a long. Thank You!

[@TechWorldwithNana]

Wow really glad to hear 😊 Thanks for your feedback 🙏

[@codycurnutte7084]

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]

How the pod communicate with backend pod ??

[@shuaibpantnagar]

@@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)

[@jacobslusser4232]

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!

[@user-ij2mg2wv5b]

This was absolutely fantastic - some of the most complicated concepts explained in a matter of mins.. you are a superstar

[@gillianbc]

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.

[@nipunsharma1945]

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.

[@TechWorldwithNana]

Great to hear 😊 Thank you for your positive feedback!

[@vks4203]

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 .

[@kenmurphy4259]

Absolutely brilliant explanation and cleared up a lot of things for me, excellent content thanks Nana

[@2sourcerer]

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.

[@prajwalgmpp]

Everytime I watch this, I will drop a comment so that it will raise through the algo ranking. Nana deserves it

[@TechWorldwithNana]

Speechless, Awesome, Marvelous, Excellent, Bingo, I don't have words to say for your teaching style. God bless you and keep it up.

[@MichaelPechner]

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.

[@csvidzz]

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! 🙏

[@meghakadur8373]

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.

[@ajaymeda1891]

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.

[@landung1623]

Nana, your videos are fantastic! I've learned a lot from them!

[@antonalekseyev9651]

This is the most useful video regarding kubernetes services exposure I've found

[@rohsin47]

So complex but explained so beautiful. Great thanks !

[@Alestrix76]

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)

[@Nizragore]

this is as clear as it's gonna get, thank you

Thanks Nana for clear the concept of service in kubernates!!!

[@colinrickels201]

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.

[@bshn]

Thank you for these video tutorials - very helpful!

[@youtubeoneverything4581]

thanks. It was a clear explanation, specially how diff. services work together

[@-long-]

If teaching is an art, you're an excellent artist
