Day 9/40 - Kubernetes Services Explained - ClusterIP vs NodePort vs Loadbalancer vs External

Welcome to day 9/40 of the Certified Kubernetes Administrator (CKA) Full Course. In this video, we will explore Kubernetes Services in depth with a detailed conceptual explanation, a live demo, and an engaging hands-on assignment.

In this video, you'll learn:
- What are Kubernetes Services
- How we use Kubernetes service to expose an application
- Different types of Kubernetes services ClusterIP vs NodePort vs Loadbalancer vs External
- Demo creating a Kubernetes service
- Imperative commands to create a service
- What are endpoints in Kubernetes
- Troubleshooting a Kubernetes service

📖 Course Schedule:
I'll release 3-4 videos per week and host live Q&A sessions on weekends to answer your questions and guide you through the CKA certification process.

🕵🏻‍♂️ Who Should Watch:
This CKA course is designed for beginners, college students, and working professionals who want to learn Kubernetes from scratch, prepare for the CKA certification exam, or enhance their knowledge. It was designed based on the latest curriculum for the CKA exam in May 2024 and uses 1.30.2 as the Kubernetes version.

Let's start your Kubernetes journey together!

Kubernetes Services seems simple now.
Thank you for all of your efforts 🙂

[nope-msrx]

Breaking down the basics with ease and helping laymen like myself make sense of all the endless documents that we can get caught up reading. You are the man Piyush!

[guntreddirajesh]

Thankyou so much piyush, i see lot of value in your content & the way you explain is awesome . on target to complete CKA certification with your videos

[kanikv]

Awesome class 🎉.
Thank you for your valuable free content.❤❤❤

[vinaykumar-qqwq]

Couldn't watch for a week. But still able to relate things pretty well. Mastery in teaching. Keep up good work.
Although I'm coming here to revise my kube knowledge. Your teaching skills are pretty neat ❤

[vm_naveen]

Thank you for the explanation on Services :)

[artbart]

Thank you! It took me some time to reproduce and understand service types.

[AI_suraj_singh_]

thanks Piyush bhai ..really helpful ..

[radhikagudidesi]

I installed Kind on the EC2 instance and am working there, while accessing the application 0f 30001 port I am getting a timed-out error, even though I added inbound rules for the node port and NACL is also allowing the port. Could you help me understand where I am getting wrong?

[karnajeetsawant]

woah.. Damn awesome video Piyush. That was a lot to cover. I dont know why but I got some kind of rush 😅. Understood all the part. However, I have this question. I know you might have covered in the videos, but still gotta ask. So, what exactly is the heirarchy in kubernetes. i mean I understood the basic like pod is the smallest unit, then node then all nodes form clusters etc. But if we talk on a different level, say replicastes, deployments etc. then what is the heirarchy over here?

[akifsalah]

So Using kind cluster we cannot run application through <<ip:port >> it has to be run through localhost?

[pradeepnpkumar]

Thanks for the Video Piyush. Can you please make a video on how k8s networking will be handled in production environment

[hetpatel]

i want to know does we had done something like port-mapping for kind cluster ?

[popurisrinivas]

Hi Piyush, How service and pod will talk each other. with help of match lables

[BhaveshKansagaraOfficial]

What would be real exposed port is 80 or 30001 because in one of my earlier particles getting output from 80 and not from 30001. I used minikube and for kind i use NodePort.

[hiranyawg]

Thank you very much Piyush can i use the Docker desktop instead of Kind

[password]

Hi Piyush, thanks for winderful stuff ! I have one question here, let say if we want to expose few more ports in kind, so we really need to re-create the cluster with new port mappings ?

[salmanbintariq]

Sir i have a question. Can we have a service without selector? And what are the industry standards either they use Type LB or something else? Because LB type will be costly.
