Thanks alot for supporting the channel 😍

[@chiragkataria3133]

Guys, if you are switching tabs apart from these tutorial, then I am sorry you are not paying attention to the tutorial. Even others have failed to explain kubernetes in depth. They just mugged up because they have large audiences, so they get easily 3 millions view on their video. But look at his content, it is so underrated. Its time to make this channel go viral so that more students are aware of this pure content. Great video Sir.

[@AbhishekVeeramalla]

Thanks alot chirag :)

[@Cloudnp9458]

Kubernetes is open-source, but there are certain distribution that provide support and build for providing user experience to its customers. Such as Open shift, rancher,tanzu, eks, aks, gke .. They are used in production.. So distribution provides additional wrapper, plugin and command line tools. But at the end of day solution is same. Most used cluster management tool is kops and then kubeadm. Kops stands for Kubernetes operations * Installation, upgradation, configuration and deleetion are part of lifecycle of Kubernetes cluster

[@neeharikagv2812]

One of the rarest videos. Previously I couldn’t understand what is managed and self managed cluster. Along with various k8s objects, in interviews they were questioning on kubeadm tool. I didn’t understand the reason for that. Got many answers in this video. Thank you so much Abhishek 🙏

you mean validation errors while validating cluster?

From next week onwards I will start applying jobs, now can u give brief(2 to 3 mins of video) idea on openings and packages for freshers,for 2+ exp and for 5+ exp so that might boost my preparation bit hard.

Hi Abhishek, thank you for your ever helpful videos. My question is on 22:18, the command you used for your cluster creation I.e kops create cluster-name ….. , as I am new to the field how do I find this commands, I know there is AWS CLI command Reference documentation online but I couldn’t locate it there. So where do you get the right commands or do I have to memorize it?

[@rohitmishra2296]

K3S and Micro K8s are not development environments, they are pretty popular for light weight edge kubernetes and IoT.

[@AbhishekVeeramalla]

They are also used as developer envs

[@DarmelKeumeue]

Thanks prof. But i'm a little bit confused with the fact that s3 buckets is used meanwhile in the previous video it is mentionned that ETCD is used as a cluster information storage in K8S

[@AbhishekVeeramalla]

Here s3 is used to store kops related things, k8s still use etcd

[@aniketubale5051]

Hello Abhishek. Thanks for such a great content you provide for DevOps people. Just one doubt i have is KOPS used in Dev, QA, UAT environment?

[@anuragnair1862]

hello Abhishek through this video i understood how clusters can be created how kops will be set up could you please tell us how we can upgrade and modify the 100s of clusters using Kops and in every organsation devops team is responsible for managing the lifecycle or there is any other platform engineering team for doing this activity. manyThanks

[@faisaliqbal7382]

Like it

[@AbhishekVeeramalla]

Thanks alot

[@ajaymannam90]

This is very helpful, thank you so much Abhishek. Anyone have idea about how much we will be charged if we create cluster as mentioned above?

[@sharathramapuram8024]

Abhishek we already fixed S3 buckets right for storage in creation of cluster then why we need to attach EBS volumes ??? 23:12

[@MohammedIsmail-ig7zr]

S3 bucket acts as storage for configuration files (etcd ) for the clusters information. etcd is seperate entitiy it does not come with kubernetes part of installation..

[@samuelude6858]

@@MohammedIsmail-ig7zr, I think there's a mixed up, S3 bucket is not a replacement for etcd, the S3 bucket created by KOPS is separate and serves as a storage location for KOPS-specific information whereas etcd remains to be a critical component of the Kubernetes control plane, responsible for storing the actual cluster state and configuration data

[@yashwanthyerra2820]

the thing is s3 is used to persist the state of cluster while ebs is used to persiste the state of pods in cluster. simple examples : s3: if a cluster becomes down or restarted that we have created for some reason . to retain those configurations and also to reconcile the change/updates that we want to do to the cluster instead doing it from scratch we use s3 bucket. they are not tied to availability zones since they are independent of clusters eb2: ebs is used for storage of pods that persists beyond its lifecycle which simply means if pod is crashed or restarted to persist data without loss like databases we use ebs . it is like external harddrive but tied to availability zones since they depend on cluster in which they are created

[@eliterajkumar]

Thanx sir

[@aliiraza4064]

Nice Explanation Sir. But Canonical claims that Microk8s can be used on production. What if I want to create self managed k8s cluster on Azure then which distro should I use and which one for on-perm?

[@Jayanta135]

Can you mention about the cpu memory storage used in production like the specifications

[@AbhishekVeeramalla]

It depends on the applications

[@Jayanta135]

Just some production specs so we can also mention it ask in an interview

[@subash7777]

we configured the kops for creating th cluster.but how it manages the hunders of cluster how will we know, what are the next steps after this process. is it the process of creating pods, deploy, service , ingress files ? could anyone explain add some information

[@AbhishekVeeramalla]

you will learn that in the next videos of this series

[@AnilKumar-w5m7h]

Hi Anna, one question please.... How the communication happen from one cluster to another cluster suppose I have one application pod running that application pod should talk to database pod which is running in another cluster..??

[@AbhishekVeeramalla]

Why do u want to do that ? If u really want to do that, you have to establish some virtual network peering or create a ingress configuration for database and only allow certain traffic and block all others.

[@AnilKumar-w5m7h]

@@AbhishekVeeramalla I got an interview question yesterday, he asked that if application pod query some information from db pod which running on another cluster, how it queries the info and how the communication happen??

[@AvinashKumar-mh6si]

Thank You Sir! I tried the commands till end. I think i missed one cmd, so "kops validate" was not working. I will try again. It created two ec2 instances - master & child. after i terminated those 2 instances it automatically created 2 instances again. I guess this is auto healing.

hi abhishek, thanks for explaining this real time kubernetes cluster. but i have one doubt that is can we tell to interviewer that we use minikube for dev and pre-production env and kops for production env? i have got rejected twice because i was unable to tell real time kubernetes concepts so.

Just for dev environments you can say we use minikube but for pre prod and prod .. you can say we use KOPS based cluster OpenShift EkS Or anything
