Kubernetes Services explained | ClusterIP vs NodePort vs LoadBalancer vs Headless Service

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!

The best tutorial on k8s services

What a great video. Not seen a single video of this quality. I purchased some mats on CloudGuru and Udemy, you know what, they are nothing compared to yours. THank you.

Lovely 🎉

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.

It’s very detailed.

pods are recreated, not restarted when they die, so a new IP will be assigned to those pods

By far the Best Explanation ever... Thank you Mam...😊

Awesome. Noone has explained k8s Servinces this detailed

Very good video, thank you.

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)

Why would Prometheus want to go via the Service to scrape? Prometheus must make sure it gets metrics from all pods, so it should scrape the pods directly, shouldn't it?

Thank you!

🙏👏👏👏

Very well articulated! Learnt a ton by going through this playlist! Thank you!

Great video ! Thanks !

One of the best tuts on services. Very well explained. 🙌

The best explanation you can find out there for K8s services. Thank you Nana!

any update for ExternalName Service?

You are the savior.. Thank you so much for this excellent explanation .

Why would you name your product Cockroach.

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! ;)

Thanks for the great explanation!

this is one best video on kubernetes services, explained in detail

(Count 2) Every time I watch this, I will drop a comment so that it will raise through the algo ranking. Nana deserves it

This channel is just a Goldmine for anyone in the software field.

You are beyond God❤

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

The most clear and easy to understand content that I found for service. You helped me a lot. Thanks Nana.

Amazing explanation.

I think one information was missing but since you showed us 2 with matching label on 2 different nodes, I just wanted to make sure I understand it.
The way a specific pod on a specific node is chosen, is by load balancing right? So I would assume a default or specified load balancing rules determines which exact pod is targeted.

Clear and perfect. Thanks.

Great video but the nerds in here simping for Nana are somewhat embarrassing. Like it's a good video, but let's get a grip. It expains services -- the end. Lol.

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.

Thank you for the detailed explanation. Got clarity.

Great explanation.

Thanks for this! You said ClusterIP is able to load balance internally, you also said NodePort internally creates ClusterIP. Is my understanding correct that if we have 3 nodes and specify service type as node port and send request to Node 1 only, it doesn't necessarily mean that our request will be processed by pod in Node 1 ? I guess, Node 1 will always receive that request but its kubeproxy will send it to ClusterIP so it decides which Node's pod replica will process it. Is it right ?

Great content! Thanks a lot Nana <3

Thye could have picked a better name than Cockroach Db, I feel somewhat gross when I read it lol. I know there's some meaning to it but...

Thanks for nana❤

Too good!

Hey Nana, I am so grateful for this video. there's nothing i can find that has helped me understand kubernetes like this.

Thanks for sharing this huge amount of knowledge here.. Really amazing

Wow, you make it seem so simple! Great Content, though I have to say the part about NodePort service was tough to understand😓

Thank you !

Great explanation

You are awesome and straight to the point THnaks a ton.

Awesome explanation !!! Have a quick doubt here , when we have kubernetes cluster on the on-premises and the application whihc needs to talk to that application can access the k8s node using nodeport and ip right as on-premises doesnt ahve native load balancer support

That was a great video! You have the gift of teaching!
