Sir Iam happy to say that your way of teaching is amazing and better than off line teaching where i learned in vijayawada.Iam 61 years retired Govt.Senior Engineer and learning Devops and AWS cloud to start second innings not for money .Only to engage my self busy with some employment. Thanks once again for your efforts and support to lakhs of SWEs who are in Villages and not able to shift to city for coaching.

Don't have words. There are lots of peoples out there won't teach anything to anyone. Meanwhile like you sir absolutely gods gifted kid who is helping lakhs of peoples and soon in Crs. Got 2 offers finally. From Cloud engineer to DevOps Finally. Thanks again sir

Your teaching skills has no match .. Thank U for providing it for free. Grateful. 🎉 What you are providing is saving time and brain damage in understanding other videos related k8s. Thank you for all those efforts.

Pod has running specification and can have multiple container. Side car container for service mesh. Service mesh is established by sidecar proxy. Deployment is capable of providing capabilities like autohealing and autoscaling. Deployment will create an intermediate resource called replicaset and then replicaset will create/rollout pod replicas.. So end of the day we are creating pods. Since replicaset is Kubernetes controller , it will implement autohealing and ensure that there are always two replicas of pods running. A Controller ensure desired state matches the current state in Kubernetes.

Superb explanation of kubernetes.

I found your channel two days ago and WOW, it is amazing. very well and precise described, thanks a lot for making these series to help others learn complex topics in a simple way

thanks bro, as expected u always come with something unique content with casual content than many youtube videos , eventually i learnt something new ,i always stay tuned to your channel ,

Thanks so much Abhishek, this is so amazing. You really simplified Kubernetes. Great Job!

Its Really amazing man, your explanations are clearly understandable and will make concept in depth

I have no words to express my gratitude . Truly a legend.

End of a good day with a very nice and informative video after watching your videos I can say Kubernetes is really easy to learn.😊

You are god in DevOps ❤❤❤❤...Love the way to teach explain...God bless you Abhishek 🙏 ❤️ ♥️ 💖 ✨️

Amazing explanation to all the concepts👏👏.. Thank you so much 🙂

The way you explained this concept is even understandable to child. Great job bro🔥

god for devops , learning in easyway is possible with your videos only far i seen.

Abhishek you are just crazy Love your DevOps videos ❤❤

Thanks, Abhishek. Very informative. 😊

Perfect explanation 🔥🔥🔥

thanks I didn't knew kubernetes flow in this way like deployment-> replica set-> pods

wonderful teaching bro successfully understand difference pods, deployment, container and responsbilites of replica set👍

Wow, i have learned about kubernetes from 4 different sources, i was still confused, but watching your kubernetes explanation is on point, i now fully understand the basics extremely well, and reason why we need kubernetes.

Awesome!!!! Explanation

Awesome explanation. Thanks a lot

Wowwww...... K8s is beautiful.. Thank you so much abhishek bro for teaching us ❤

Thanks abhi very simple way, we can understand the concept # bappa bless you bhai

I was so lost into the video, it is your amazing teaching sir.

please explain ssh -isfgg

Just Awesome 👍

Thank You Sir! This video was awesome 🔥

learnt alot from you sir... THANKYOU

Thanks a lot, Abhishek Sir wonderful explanation 🤩🤗

extraordinary explanation - thank you @Abhishek

Thank You Abhishek , I learned something new Today

thank you Abishek

Great learning experience brother....

Hi anna. Thanks a lot for your videos. I am able to understand all the concepts with ease. I request you to make a video on HPA and VPA to help understand auto scaling better.

Crystal Clear :)

Always start your videos with like.. crystal clear explanation ❤️ can you please show us how to do auto scalling here

Hi..Is there a way to build the image in Kubernetes and use it in the creation of POD, instead of pulling the image from the registry? also, how do we specify our own image registry inside the pod.yaml or deployment.yaml file?

hey abhishek i am having an error i did minikube start it created node with no role. what to do ?

Hi Abhishek, I am following all the steps mentioned in your video but I am getting this error when executing this command - kubectl apply -f pod.yaml Error - The connection to the server localhost:8080 was refused - did you specify right host or port ? Can anyone please help me ?

Abhishek your awesome, I have a small query, I have developed magento app using Ubuntu has base image, in order to copy the files I have written a script in entry point, so every time new pod spins up it starts the same steps, is there any way where application files will be automatically copied, like official MySQL images which copies everything to pvc automatically

Thank you ^^

Hi Abhishek, if deployment itself gets deleted, including pods everything will be deleted. Is there any replica set kind of mechanism for the deployment?

Hello Abhishek.. Thanks for the series and good explanation with deployment example. I was just wondering if replica set image can be deleted or killed. I tried in the lab but it said no such resources. If it can be killed then ts there a new replica-set created or we need to re-run the deployment.yml?? Have you encountered such situation?

Better way of explanation

Sir, I must say k8s have replica concept but your replica not possible 👏👏👏👏

Day 34 Successfully Done

Well explained 👌👍

You provided a great explanation of the concepts. However, I would like to know where to indicate auto-scaling based on incoming traffic, as you only covered auto-healing.

error parsing deployment.yaml: error converting YAML to JSON: yaml: line 5: mapping values are not allowed in this context this error im getting. pls help resolving it.

Thank You ❤

How to add new node to an existing k8s cluster?

This is for people who don't understand "Replica Set": -> In k8s, there is a concept called controllers (we saw this in architecture video). The main work of controller is to watching the POD is running in desired state or not. -> If not it sends the message to scheduler to create a new resource to achieve the desired state. -> One of the controller is called "Deployment". -> "Deployment" first creates "replica set(actual controller)" managed by "deployment" and replica set creates and manages the POD. -> Still confusing see the bellow picture: +-----------------------------+ | Deployment | | (desired state: 3) | +-----------------------------+ | | creates or updates | +----------------------------+ | ReplicaSet | | (desired state: 3) | +----------------------------+ | | creates or updates | +----------------------+ | Pod | (POD -> execution environment for the containers) +----------------------+ | | runs the containers | +----------------------+ | Container | +----------------------+

Nice and useful

Is there any repo for the kubernetes Zero to hero series ??

Hi Abhishek, Please make a video of difference between pod, container and cluster and nodes in kubernetes with examples.

Hi Abhishek, I am in Canada and Enjoying your course. I am stuck at this error when deploying using deployment.yml in minikube with error: Status ImagePullBackOff and no IP addres assignment. Researched a lot and tried many things but I am not moving. Please help.

Good job

Hi bro When you’re going to start docker and k8s. Pls let me know. We need to learn from scratch soo

Hi brother... Your videos are more n more helpful to everyone... I have a small doubt... In case, in an interview, if they ask us to write a pod or deployment creation yaml file, how can I write??? Because In the interview they don't allow Google or something.. like how can we remember all these syntaxes???

Excellent

Abhishek sir just one question, as you are saying difference is that you write command in CLI in docker and in pod we write the commands in yaml file so the same is for docker in a docker-compose file ?

Agar hum application ke saath saatg database ko bhi deploy kare or replicaset banaye..let's 5 replica of one db.. O sare db hum actual mein product pe kaise manage karhe kubernetes ke THROUGH? O hum kaise kare.. Please Bhai Batado..Eh mein Sabse barha wala confusion hain!! One thing I tell You.I crack Junior DevOps Engineer interview Just watching your Videos and practising those Things. Buttom from My Heart You gave A Life. Now I can see Clearly All Things Of My future. You are really Inspiring...Keep Going.. Aishe savka vala karo allah aapka bala karega..doua hain hum sab logoka.. Love You Bhai From Bangladesh ❤️❤️❤️

Hi @abhishek, at timestemp 24:44 - after the deletion of old POD when recplica controller creates the new POD will the IP Address and Port be the same? asking because if the user is accessing a website on POD1 then how will it be redirected to POD2 ? Thanks in advance.

❤

❤Thanks

hi sir, can you please tell us what is meaning of -it in docker run command, as per my knowlege 'i; stands for interactive and 't' stands for terminal, please correct me if i am wrong.

Hey Abhishek, what is difference between apps/v1 and apps in apiVersion(for pod and deployment) in yaml file?

great explanation abhishek!!! how can we do the same for auto scaling, please enlighten us.

What is namespace ?

i got this error : Error from server (BadRequest): error when creating "pod1.yml": Pod in version "v1" cannot be handled as a Pod: strict decoding error: unknown field "metadata.spec"

Hi abhishek, if someone deletes the pod, deployment will auto-heal it, but what if the case if someone deletes the deployment?

Abhishek bhai Docker-compose are also capable to run multiple container.. Is pod or docker compose are equivalent?

Anna horizontal pod scaling pi oka video cheyara

what if someone delete the deployment ??

Can we create a replicaset directly instead of deployment? If Yes, then why we create a deployment instead of RS?

Nice one

Hai Abhishek thank you so much for your content and help. Abhishek can you make a video on how to Perform code quality using SonarQube and how Integration testing is done in the Devops process. This is my personal request to learn those important topics Abhishek. Please as per your free time on this course try to cover this topics also Abhishek. Thank you

Great explanation. One question like if we change image file. And apply the kubectl deployment with new image. Will old pods be deleted or both will run at same time?

Yes but why we are using the label, selectors and template ??? If copy and paste then what is the point of explaining this thing?? Why there is a selector in the Object spec?

Hello Abhishek Your videos are awesome very intresting. Here I've a doubt that what is the difference between healing and scaling ?

Day-34 done ✅️

Hi Abhishek. Can you please tell the reasons why pods will get deleted other than network issue.

in pod communication how ip address define it's by default or we can set that in real world?

Hi Abhishek..one doubt.. today i have attended one online workshop for Docker-compose. Is this same in Kubernetes deployment.yaml. are both are different..?

One small doubt, You cleared about auto healing but doesn't show how auto scalling happens, instead of that you increased pods by manually. Plz tell me anna

Without using helm or Agrocd or any other tool, can I directly use K8s to deploy my application into production?

Are you covering helm also in this devops 45 days training

Abhi anna one small doubt Cant we delete pod permanently..??

what if i delete the Replica set, or Deployment will my PODS got deleted..??

Hi Abhishek, what happens if someone deletes a replicaset?

Replica set, Replication controller and Deployment are we can say it is POD controller.

abhishek can you make a cheatsheet interview questions on kubernetes?

What is labels and selectors in deployment ??

hello brother, can you create a post in linkedin how much computer networking required for devops

please do some real time deployments

Abhishek,How can I connect you?

Bro kindly explain the name space
