► Thanks Cockroach Labs for sponsoring this video! 🙌🏼

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!!

@VR-cr9wn 2 года назад

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

@VR-cr9wn 2 года назад

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 2 года назад

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

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.

@rmagnum2002 3 года назад

"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!

@2sourcerer 2 года назад

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.

@mikhailkulak3203 3 года назад

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:)

@codycurnutte7084 3 года назад

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 Год назад

How the pod communicate with backend pod ??

@shuaibpantnagar Год назад

@@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)

@sharma2494 Год назад

@jacobslusser4232 4 месяца назад

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!

@gopikrishna7779 Год назад

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.

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.
