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...
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.
### 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
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.
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
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 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...
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.
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.
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 👏..
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!
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.
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.
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..
@abhishekveeramalla Are Sir, I searched udemy coursera everything but yours is best among all, I am cloud engineer at Hyland Is there any paid course of yours as well??
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.
Hi Abhishek good video. But have some doubts 1)You mentioned that Docker shim is a container runtime, but based on my research, I found that the Docker shim is actually an intermediate layer that processes requests from the Docker daemon and translates them into a format understandable by the actual container runtimes, such as containerd 2)I we choose the HPA instead of replica set then there is no limit for the number of containers created am i right? 3)What is container run time used on node i means if i use docker then that container runtime is used by Kubernetes i am referring to the container runtime that you mentioned in the worker node. Thanks Abhishek for the video really informative and engaging ♥
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"
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.
K8S means --- In kubernetes start with K and ends with S letters and in-between 8 letters are there. Because of this we are saying that K8S. Abhishek please correct me If I am wrong here.
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
Hi Abhishek, A quick question containerd, dockershim, cri-o are all daemons, correct? And the actual runtime is runC or kata. So can we say that container runtime encompasses two components? A high level process called daemon(containerd, dockershim, cri-o) and a low-level runtime in runC or kata or crun?
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...
Thanks alot for the kind words .. Can you please share the channel with your friends and groups ..
Keep doing great work Abhishek. Appreciate your efforts 👍
I was thinking the same thing.
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.
😍😍
I have struggled with everything in Tech before I met you. Thank God for Indians, thank God for your life
### 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
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.
people who watches your videos wont feel any doubts, that much clarity has been inbuild in your videos
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
I bought that too, but still feel like i know nothing in kubernetes. Thanks to Abhishek for connecting all the loose ends so effortlessly.
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❤
Thanks a lot

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.
that component is api server since every request of resurce creation first has to go through the api servre.
Best explanation of Kubernetes arch ever seen. this course is recommended for every devops aspirant.
😍😍
Abhishek you are a gem! I pray for you and your family. Thanks a ton for taking care, creating such amazing courses!
Thanks a ton
Hello where can I find complete kubernetes course , here I can't able to find all the vedios .
Thanks in advance
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.
Amazing way of teaching. Making concepts more interesting. Thank You Abhishek.
The way you are explaining the Kubernetes(Where everyone scares).
Just wow.🤩
Most welcome !!
Thank You ABishek for easy-way explanation, with you we are becoming K8S masters
Hands down, That is the best Kubernetes explanation ever. You are really a Master at Work.
your teaching skills are amazing...
Thanks alot abhishek sir for explaining k8s arch in detail
Awesome Explanation. you are making complex topic to understand easily
Thanks a ton
Literally he looked at the kubermetes as a whole enterprise working, like boss and workers 😂. The best explanation ever
❤️
After watching this video easily understood the k8s architecture....tnq bro you are doing great job for us🤝❤️
It's my pleasure
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 👏..
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 🙏
Great @Abhishek! Thank you so much!!!
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!
😅
This was more than just a course video, Thanks !
You're welcome!
Understood Every Bit of the Video, Fantastic explanation Abhishek sir 🔥
one thing for this video.... just crisp and clear
Thanks alot
Thank your from the bottom of my heart this huge information for free more wins for you Sir❤
thank you very much Abhishek. learning from cameroon cemtral africa
Thanks !!
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.

Amazing .. Thanks
sir you make so easy to understand k8s hats off you sir
The way you Explained was Awesome👌👌
❤️
Thanks a lot sir. Greatful to you.
A big thanks for outstanding kubernetes sessions👍👏
thanks a lot guruji...ur my Devops Guru😍😍
very well explained Abhishke bhai...great learning from the session.
It's my pleasure
Superbly explained
Thank you 🙂
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.
😍😍
Amazingly explained.Thank you so much Abhishek :)
Most welcome
nice explanation brother..k8s 8 letters between k-s
Yes, correct
Excellent i grasp every word of your session much more informative.
Thank you so much 😀
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..
Thank You very much for share very imp content for Kubernetes.
Excellent video
Thank you very much!
AWS GCP Azure are lols. ABHISHEK CLOUD IS THE FUTURE 😊😂
Lol
@abhishekveeramalla

Is there any paid course of yours as well??
😂😂
Really Awesome Bro, clear explanation. Thank you
Awesome. Please share the videos with your friends and groups
Just awesome. Thankyou so much
Most welcome 😊
Great Job
Thanks
This session is gold 🙂
Thanks
really nice explanation
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 ⌚ 🙏
Welcome 😁
Very Useful....tq
Because word Kubernetes has 8 letters between the first and last letters
Awesome 😎
Just mind blowing..
Thank you
Awesome job as always!
Thanks again!
Lucid & clear
Thanks
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.
Yes yes
My first comment, you are hero of k8s.
Thanks alot
awesome teaching
Nice explanation Abhishek. Thanks:)
Welcome
Gooood explanation...😊
Thanks a lot
just one word awesomeeeeeeeeeee
Thanks
Hey Abhishek, you are just awesome.
thank you .I have gone through Udemy courses related to k8s but none of them explained like you
Thanks 🙏
thank u for this video!
Thank you so much abhishek sir
Loved it ❤❤
Hi Abhishek good video.
But have some doubts
1)You mentioned that Docker shim is a container runtime, but based on my research, I found that the Docker shim is actually an intermediate layer that processes requests from the Docker daemon and translates them into a format understandable by the actual container runtimes, such as containerd
2)I we choose the HPA instead of replica set then there is no limit for the number of containers created am i right?
3)What is container run time used on node i means if i use docker then that container runtime is used by Kubernetes i am referring to the container runtime that you mentioned in the worker node.
Thanks Abhishek for the video really informative and engaging ♥
Nice Abhishek
Thanks 🙏
Good morning abhi guru👋👋👋💕
Hi Abhishek ….Thanks for the wonderful video…can you please tell the difference between ccm and terraform?it shall be really helpful
You are a legend 🥰
😀
Kubernetes is commonly abbreviated as "K8s", which is a shorthand notation that replaces the eight letters between "K" and "s" with the number 8.
Awesome
Thank You ❤
Thank you so much 😀
K8s - because Kubernetes - 8 words in between K & S
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
Awesome
It's like a naming convention, n there r exactly 8 letters in between K and S. I think it's called as numeronym
Awesome
Thank you ^^
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"
good
you seriously nalied it sir .
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.
K8S means --- In kubernetes start with K and ends with S letters and in-between 8 letters are there. Because of this we are saying that K8S. Abhishek please correct me If I am wrong here.
Great Explanation! Can you Suggest steps to implement "I want to run Automation script of selenium with java using Kubernetes?"Thanks in Advance
Hi @Abhishek
Your videos are too good and easy to understand. Iam looking for the concept Node affinity. Could you please help me here.
🙏
Could you please help me on Node infinity topic.
8 standing for the number of letters between the “K” and the “s” so it is called k8s
Abhishek please explain with the help of cloud example? install k8s on aws and explain
- "Kubernetes" has 8 letters between the "K" and the "s"
- "K8S" replaces those 8 letters with the number 8
in between K and S total 8 letters as a shortcut we call it as k8s
Day-31 done ✅
Great, keep going
There are eight(8) letters in between K and S so it is called K8S
K8S -> Counting the 8 letters between the K and S in term KUBERNETES 😅...Am i correct my mentor ?
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
Yes. You are correct. It notifies the API server
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.
Awesome
Kubernetes is also called as k8s because in between k & s there are 8 alphabets
So basically , you wanted to say that master component is control plane component and worker component is data plane component
Hi Abhishek,
A quick question containerd, dockershim, cri-o are all daemons, correct? And the actual runtime is runC or kata.
So can we say that container runtime encompasses two components? A high level process called daemon(containerd, dockershim, cri-o) and a low-level runtime in runC or kata or crun?
Between K - S there are 8 characters in Kubernetes so its commonly callaed K8s
if you give the practical experience of each and every thing like kube proxy how it works, controller manager and cloud controller thx
Yes
