Day-31 | KUBERNETES ARCHITECTURE USING EXAMPLES | Kubernetes is Easy  

I don't know i become a hero after completion of this course but I truely tell that from the bottom of my heart you are the real hero for sharing such a realistic data for free...

I have struggled with everything in Tech before I met you. Thank God for Indians, thank God for your life

Thank You Sir! It was easy to understand! Pod - A Kubernetes pod is a collection of one or more containers, and is the smallest unit of a Kubernetes application k8s architecture # Control plane (master node) ## api server - core component of k8s, accepts all incoming reqs, exposes k8s to external world. ## etcd - key value store, cluster related infos. ## scheduler - scheduling pods or resources on k8s, receives info from api server & acts on it ## controller manager - ensures controllers like replica set are running ## cloud controller manager - like terraform # Data plane (worker node) ## kubelet - creates pod, ensures pod is always running ## kube proxy - provides networking like Docker0, default load balancing ## container runtime - runs container inside pod this is my basic understanding. will improve it in future.

Kubernetes (sometimes shortened to K8s with the 8 standing for the number of letters between the “K” and the “s”) is an open source system to deploy, scale, and manage containerized applications anywhere.

### Architecture of K8s - Data plane (Worker Node) → 3 components: 1) Kubelet (Creating and managing pod) 2) Kube Proxy (uses iptables in Linux machine) 3) Container Runtime (enviornment) - Control Plane (Master Node) → 1) API Server (exposes to external world) 2) Scheduler (Scheduling pods or resources in K8s) Receives information from API server 3) etcd: Backup service (key value store) 4) Controller Manager Example: Replica Set 5) CCM (Cloud Controller Manager) - No need for on-premice

Thank You ABishek for easy-way explanation, with you we are becoming K8S masters

Appreciating your work Keep this things always free cause once a wise man said - “Only knowledge is the one which get increases when you share it with another” Love your teaching❤

I don't know how he is teaching us in easy way? I have bought the KodeCloud as well but Abhishek is literally providing us in depth knowledge whatever he takes it. The amount overview in this Video I got is awesome. Thanks again bro

Abhishek you are a gem! I pray for you and your family. Thanks a ton for taking care, creating such amazing courses!

Control plane components are - api server, etcd, scheduler, controller manager, ccm _ cloud controller manager. Node components - kubelet, kube proxy, container runtime Container runtime is equivalent to dockershim in docker Kubelet is responsible for running and ensuring pod is always running. Kubelete interacts with container-runtime to i e cri-o or xontainerd to run the container inside pod. If pod is not running kubelet will inform kube_apiserver. Kub *Kube-proxy - provides, networking, ipaddresses and load balancing for the pod to communicate, Implements iptables..

Thanks alot abhishek sir for explaining k8s arch in detail

Kubernetes is commonly abbreviated as "K8s", which is a shorthand notation that replaces the eight letters between "K" and "s" with the number 8.

At 9:42 you mentioned "There is a component in k8 I'll keep that component in suspense" I just love the way you teach the subject. Amazing teaching skills. More Power to you.

I tried learning the architecture from other paid Udemy courses but didn’t succeed. @abhishek, you definitely deserve a spot in the Hall of Fame or even a statue at Madame Tussauds for your outstanding teaching!

Best explanation of Kubernetes arch ever seen. this course is recommended for every devops aspirant.

The way you are explaining the Kubernetes(Where everyone scares). Just wow.🤩

This was more than just a course video, Thanks !

Awesome Explanation. you are making complex topic to understand easily

After watching this video easily understood the k8s architecture....tnq bro you are doing great job for us🤝❤️

I am going through the DEVOPS ZERO TO HERO course, today i started KUBERNETES after gone through the DAY-31 k8's architecture video i got a clear idea on CONTROL PLANE and DATA PLANE and total components in it. THANKS to #ABHISHEK VEERAMALLA.

after 30 days. Spending this much of my time on your videos is really really worth of watching and still excited about next next videos and getting interested on the tools of DevOps. Much appreciated for your efforts Thanks a lot man.

Understood Every Bit of the Video, Fantastic explanation Abhishek sir 🔥

nice explanation brother..k8s 8 letters between k-s

sir you make so easy to understand k8s hats off you sir

one thing for this video.... just crisp and clear

Hands down, That is the best Kubernetes explanation ever. You are really a Master at Work.

I am following your tutorial and it's like you give a detailed explanation and that is very easy to get into our minds , I can't thank enough for this Abhishek anna and even I'm making notes from few classes that is helping me to understand whenever I see them , Thankyu Abhishek , Hatsoff 👏..

the ans for this is that The abbreviation "K8s" is for the word "Kubernetes", which is an open source system for managing, scaling, and deploying containerized applications. The "8" in "K8s" stands for the number of letters between the "K" and the "s"

Very Useful....tq Because word Kubernetes has 8 letters between the first and last letters

Very well explained k8s architecture 👍i used to scare about it a lot but now its very clear to me🤗 Thank you so much Abhishek 🙏

thank you very much Abhishek. learning from cameroon cemtral africa

thanks a lot guruji...ur my Devops Guru😍😍

AWS GCP Azure are lols. ABHISHEK CLOUD IS THE FUTURE 😊😂

Thank your from the bottom of my heart this huge information for free more wins for you Sir❤

thank you .I have gone through Udemy courses related to k8s but none of them explained like you

Thank You very much for share very imp content for Kubernetes.

The way you Explained was Awesome👌👌

Hi Abhishek I am always scared of these Docker and Kubernetes, and had lot of hesitation to learn as I felt these must be very complicated (from the paid coursed i ahve taken🙄) even to understand theoretically , Thanks a ton you made me understand K8s so well, it really felt easy. (I am not sure how my practical exposure will be :🤔 i am sure i will learn from your videos. Kudos to you.

In between the letters k and s there will be 8 letters 'ubernete'. That is the reason it's short form is k8s k'ubernete's

Just awesome. Thankyou so much

8 standing for the number of letters between the “K” and the “s” so it is called k8s

very well explained Abhishke bhai...great learning from the session.

Amazingly explained.Thank you so much Abhishek :)

A big thanks for outstanding kubernetes sessions👍👏

It's like a naming convention, n there r exactly 8 letters in between K and S. I think it's called as numeronym

Great explanation Abhishek! Found it really useful. Understood the workflow and the use of K8S components. Now my doubt is can we use this simple architecture to explain it to the interviewer? Thanks.

Excellent i grasp every word of your session much more informative.

This session is gold 🙂

Hi Abhishek ….Thanks for the wonderful video…can you please tell the difference between ccm and terraform?it shall be really helpful

Good morning abhi guru👋👋👋💕

Superbly explained

in between K and S total 8 letters as a shortcut we call it as k8s

Really Awesome Bro, clear explanation. Thank you

really nice explanation

Kubernetes is also called as k8s because in between k & s there are 8 alphabets

Between K - S there are 8 characters in Kubernetes so its commonly callaed K8s

thanks for u r knwlg and a special thanks for u r suggestion to add the knwldg shared by u to LinkedIn ..... thank you Abhishek for u r valueable ⌚ 🙏

Lucid & clear

So basically , you wanted to say that master component is control plane component and worker component is data plane component

K8s - because Kubernetes - 8 words in between K & S

Kubelet will always ensures that if the POD is running or not. suppose if one of the POD is not running Kubelet will inform to Control Plane Component. to which Component it will inform ? my guess is Kubelet will inform to API Server

Thank You ❤

- "Kubernetes" has 8 letters between the "K" and the "s" - "K8S" replaces those 8 letters with the number 8

Great Explanation! Can you Suggest steps to implement "I want to run Automation script of selenium with java using Kubernetes?"Thanks in Advance

There are 8 letters between K and S. That's why also known as k8s

Nice explanation Abhishek. Thanks:)

Excellent video

Just mind blowing..

Awesome job as always!

just one word awesomeeeeeeeeeee

Abhishek please explain with the help of cloud example? install k8s on aws and explain

Today only in interview they asked this question and i was not able to answer but ya make sure I will able to answer this question from next onwards.

Hey Abhishek, you are just awesome.

Hi Abhishek! Thank you very much for your videos. I am really grateful. One feedback though, you didn't explain in part 30 and in the beginning part 31 what node is. But you are talking about it assuming that the beginners will understand it anyway.

You are a legend 🥰

awesome teaching

Thank you so much abhishek sir

Great Job

Counting the eight letters from "K" and the "S"

K8s = k(ubernete)s 8 latter in prentices that why its call k8s

My first comment, you are hero of k8s.

Loved it ❤❤

K is the starting word S is the ending word, and 8 is for the words between K and S

Hi @Abhishek Your videos are too good and easy to understand. Iam looking for the concept Node affinity. Could you please help me here.

Gooood explanation...😊

What's the difference between controller manager and kube proxy?

if you give the practical experience of each and every thing like kube proxy how it works, controller manager and cloud controller thx

One request from my end , can you please show some real time scenarios in kubernetes

Between k and S of Kubernetes has 8 characters , hence the reason k8s .

you seriously nalied it sir .

Kubernetes: take first and last letters and replace the middle 8 letters 'ubernete' with 8 = K8s = Kubernetes

8 letters between K and S

There are 8 words exists between K and s that's why we can call k8s

K8's : In the case of "Kubernetes," there are 8 letters between the 'K' and the 's,' so it's abbreviated as "K8s."

because it has 8 letters k to s in between

sir if you launch any paid courses i will definetly buy your courses

Thank you ^^

Day-31 done ✅

eight alphabets in between K and S

In Kubernetes Master components, where is KUBECTL, you missed it or they removed it?
