Thanks! bro
Thanks alot for supporting the channel 😍
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.
Thanks alot chirag :)
Thanks a lot for these detailed Kubernetes videos.
You are the best tutor for devops in India
Thanks a lot once again.
Hats off to your efforts.
This man is a savior!!
Extremely simply, straight forward and to the point. Even my paid udemy courses are flop
Thank you so much 😀
Thanks Abhishek for clarifying complex things in a easy way..really helpful 👍
Thank you for your dedication to put out this GREAT free content daily! Thank you for showing us what is actually used in a real work environment. You are setting us up for successful interviews.
❤️❤️❤️
Thank you sir for excellent session 💯
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 are welcome
So much useful info thanks to you for putting efforts in doing videos without any expectation.
Welcome 🤗
Great one Abhishek! Thanks for sharing this valuable content.
My pleasure
@abhishek sir big thanks to you to help me to creak a interview of devops profile. Yesterday I got a job in devops profile
Thanks for your video and project. You clearing my doubt to giving reply on my each and every comment .............................BTW thanku so much abhishek sir for your support & such imaging content
Amazing Rohit .. I am so happy for you. Would you like come on to the channel and share your journey. It will help our subscribers family.
@@AbhishekVeeramalla ok sir
Hi bro
Can yu share ur preparation?
Your explanations a too nice to hear, you easily get the informations behind the concepte so easily. Thank you man
Glad you like them!
Thank you abhishke for expalining this.. i really got good understanding of why we need to use kops and why we need to create S3 etc etc... you are amazing❤
Thanks
Great support for DevOps guys.....keep it up...
Thanks !!
Very well articulated and explained 👏
Glad you think so!
Really thanks Anna best kubernetes video ❤️❤️ Hats off
Awesome
Wao, Great explanation,You always come up with an amazing content!
Thank you so much 😀
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
Kudos. Nowhere in entire CZcams world has given such a crisp and Clear Explanation. Please include the real time scenario based interview questions related to Kubernetes for experienced resources. and the issues which you encountered in your day to day routine activities.
❤️
Thanks for the video. recently i given interview and dont know about k8s distribution and Tanzu that he asked to me But after watched your video my doubt is clear now.
Nice and I am recaping my knowledge on k8s by watching your videos abhishek garu thank you!
It's my pleasure
Thanks.
Well noted!
Glad it was helpful!
Amazing Contents!!!!!
Amazing content
again awesome, sir

Thanks !!
Thanks!
Thanks for supporting the channel 😍
You are really amazing Abhishek, thank you soooo much🎉🎉🎉❤❤. Truly you are the inspiration for learning Devops and you are making it more interesting.
I gave an interview for Cricbuz the most of the questions asked was all from your videos, will go through all the topics again
You deserve soo muchh!!!
Amazing. All the best 😍
Thank you ^^
well explained 👍
❤️
very clear explanation, one small doubt in real time companies, kops will be used because as master should be managed. In down time there will be issue right
you are very informative bayya
thanks
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?
U deserve the CEO position for Kubernetes ♥️
Haha 😅
Sir please one complete series for OpenShift also ... and thanks for this K8s.. your way of teaching is just impeccable ..🙂
Openshift is mostly same as k8s.. very less changes
Thanks Sir ji... will keep a focus on K8S first, completing the eks series one by one ..
Thanks a lot.. Sir how can I talk to you 1:1 ? Currently following you on CZcams, telegram, and LinkedIn..🧑💻
Firstly thanks a lot. Course is going too good, i am getting bunch of knowledge on every tool and day by day i am growing with confidence. 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.
❤️❤️❤️
Thanks again bro. One doubt to clear, Does Minikube has the capability(cloud controller) to talk to cloud for example to create load balancers or Ingress controller?
Good 👍
Thank you! Cheers!
Very nice
❤️
Thanx sir
Thank You ❤
Welcome
Hi Abhishek brother your way of explanation is awesome, if possible please make a session on EKS
There is a end to end video on eks. Check the Aws playlist
Hi, thanks a lot for the video. Could you please tell how to destroy the cluster using command?. Thank you.
Thanks a lot Sir, for sharing the Realtime devops knowledge
could you please suggest how do I put everything together and explain in interview what
are my roles and responsibilities on each tool as a devops engineer in my current organization
that would be of great help. Thanks
❤️❤️
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?
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?
Day-32 Done ✅️
Thanks, Anna. Trying very hard from a couple of days to learn more about DevOps.But unable to find good resources and unable to understand it..
Also if u have any paid programees also , would like to join ..Like to get a job ready..Thank u very much for this videos anna very helpful.E year lo alayna devops lo job kodtha
Ha ameerpet velli course cheydam kanna ni degra nerchukodam best
Thanks 🙏
kindly make a video of using mac m1 for devops.
@abhishek: Which tool mostly used with AKS instead of KOPS?
Like it
Thanks alot
you are using the AWS services and showing the practical demonistartion
but i would like to ask if how to use over the VM(Ubuntu ) please let me know
Thank you
tanq bro
Welcome
Again to use it on minikube it requires 2cpu 4 gb ram which is chargeable right?
hi abhishek, when the market will go as usual... i.e we get interview calls more
need hyperwise installation with configuration etc
Was there a github for this specific k8s episodes?
Thanks please do share video on entire Ci CD setup of k8s
❤️
Abhishek bro thinks he is HERO !! ⭐⭐⭐⭐⭐
😅
we are using EKS and OpenShift in our project.
Hi verma , i need help that realife project explaination. Coz I wanted to shift domain i don’t have any experience on aws devops can we connect
❤
Thanks
23:51
Can we create cluster 1st time or that also will be charged. ?
But how will we delete the cluster after the exercise is complete is there a command for it?
Your videos r really helpful can you do a video on k9s
Thanks .. I will try
In azure we need to install python and cli?
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.
Does Rancher have same functionality as "KOPS" ?
please make videos on AKS
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
Thanks Abhishek 😊
Abhishek, I have small question what is the difference between KOPS and EKS ? Because If KOPS is good then why it is not in most widely used list which you explained in Video at timestamp 9:36
bro kops is Replacement of kubedeam which we will install the all kubernetes packages
@@vaibhav.v6403 thank you vaibhav
Hi Abhishek
I need some info regarding job opportunities in future.
Now a days calls are very less, when we expect more calls as usual.
Thanks for content you are providing.
I am learning so many things through your videos.
Same Question :(
Please wait.. the market is getting better
I have created kubernetes cluster in EKS using yaml file.
Just be careful about the billing.. EKS is not free
👍
hi bro
install dependencies are not working .
can you guide
Is there any free linux platform for practicing kubernets like katacoda, GCP etc,I am trying install in windows but not happening, I am little good in linux..need Linux machine for practicing..trying many ways but not getting ,pls help..
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..??
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.
@@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??
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
Here s3 is used to store kops related things, k8s still use etcd
Thanks for the Videos Abhishek, i have one query here can i use KOPS tool for setting up the Kubernetes cluster in Azure.
Same query I do have
Answer is Yes .. but KOPS is not very stable for Azure
how to remove kops validation Failed Error ??? i have been stucked on that since 4-5 days. please reply.
Can you mention about the cpu memory storage used in production like the specifications
It depends on the applications
Just some production specs so we can also mention it ask in an interview
Hi Abhishek
Thanks for the videos
May I know if with this knowledge could a 4 experience guy clear interview and start working on devops
You need cloud knowledge as well.
Yes, you can
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
you will learn that in the next videos of this series
Good day sir , this export path ="path" I don't understand it
Hello Abhishek hope you are doing great , could you please share the kops installation guide git url , i am not getting in the repo
You can get that from their official docs
Thanks bro . Lots of appreciation for your dedication and effort . You are a gem bro .
Abhishek we already fixed S3 buckets right for storage in creation of cluster then why we need to attach EBS volumes ???
23:12
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..
@@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
The connection to the server localhost:8080 was refused - did you specify the right host or port?
Sir, I'm getting this error when running kubectl apply -f .yml .... How to troubleshoot this sir? I've tried various methods from stackoverflow . Couldn't resolve it.
Your tomcat server using your port no 8080..please be free first after you can use
@@gauravmittal6909 Thanks sir. Actually this command worked after starting minikube
Yes .. the cluster was stopped:)
I'm trying to create s3 bucket in Mumbai region instead of us-east-1 using ap-south-1. I'm encountering the following error. "An error occurred (IllegalLocationConstraintException) when calling the CreateBucket operation: The unspecified location constraint is incompatible for the region specific endpoint this request was sent to." I have tried location constraint as follows. "aws s3api create-bucket --bucket my-bucket-abc --region ap-south-1 --create-bucket-configuration LocationConstraint=ap-south-1"
Issue stillnotresolved and error is "An error occurred (BucketAlreadyExists) when calling the CreateBucket operation: The requested bucket name is not available. The bucket namespace is shared by all users of the system. Please select a different name and try again."
@Abhishek plz suggest me.
Thanks
Bucket Names bust be globally unique. that's the reason you're not able to create bucket with the same name. Try giving a unique name for the bucket.
As a fresher to get a job single cloud kubernets devops is to set
Sure
@@AbhishekVeeramalla tank u
Hi
I need devops, aws,Terraform, k8s interview questions n answers.
Plz provide...🙏🙏
Everything already available on the channel.. pls check
Hai Abhishek, please share a link to install minikube on our local system or EC2 insatnce to practise k8s. thank you
minikube.sigs.k8s.io/docs/start/
Thank you
Really Abhishek Thank you so much for your Help to Devops community and people like me who are getting more knowledge about k8s.
I just wanted to know that how do manage your time like your work and doing all this things on youtube.
Really your work is much appreciated and keep going like this Abhishek 👍 👌 🙌 🙏
Right now there are no calls any idea from when the calls are going to start.
Market is getting better .. Keep trying
Abhishek anna koncham confusion ga undi.. title emo ela clusters manage chestaru ani undi .. but video lo aaa topic cover ainda bro .. koncham confusion ga undi .. can you elaborate bro .. and you showed only installation in this video but how do we manage. ? Sorry if this sounds silly .. but reply me please
Hi Priyanka. . As I told you in the video .. Installation, Managing .. Upgrades, deletion everything is done by KOPS.
KOPS is Kubernetes operations.. as a devops engineer you can manage everything related to update, delete and create using KOPS.
@@AbhishekVeeramalla thankyou for the reply brother
Abhishek bhai can you tell me how we make a connection to our Jenkins CI/CD pipeline to KOPS, in my interview I said I make Kops as jenkins server slave but he said this is not a best practice
why do you need kops for jenkins ?
@@AbhishekVeeramalla okay I got it we install Jenkins on kops correct
Are kops and kubectl both are same ?
No KOPS is used to create, delete and update Kubernetes clusters .. where as kubectl is for managing resources like creating pods in the cluster.
Unable to connect to the server: dial tcp [::1]:8080: connectex: No connection could be made because the target machine actively refused it.-- Please help me how to resolve this issue
Where r u getting this error ?
Explain slowly sir
Thanks for the feedback
18th Feb, 2024
TimeStamp 22:26. I am using free tier of AWS. To be sure, if we create a cluster with name **.K8s.local and dont update then we will not be charged ? is it correct ?
note: we cannot use the free tier instance for running the k8s cluster using kops, it won't be validated. Better to use other instances with higher cpu power.
I tried ec2 free tier😀what was the most interesting part was i deleted the instance without deleting the cluster details. and when i look back in ec2 instance node was still running. i deleted many times but didnot work. Again I follow same steps to create and delete the cluster. Finally I got peace😇
