yes abhishek looking forward for the in depth of crd ,cr etc..thank you for good overview...
Suuuuuper se bhi uuupar. What a fantastic explanation you have given for CRD in very simple language. If you can arrange CKAD or CAD be it paid or not I dont care I will be the first person to join your course
wow.. no words.. Thank you so much
Awesome job!! Thanks for breaking this down.
❤️
Hi Abhishek, thank you so much for concept that you covered and given for us. And I am just unable to find words to express thanks and love towards your effort and sharing a such knowledge. Thank you once again. You started new course on AWS that also a great work.
Thanks alot
Thank you 🙏🏼
Fantastic explanation
Thanks Abhishek
Thank you so much on detailed explanation. much appreciate.
Most welcome
Awesome video
Trying learning every day from your videos❤
Welcome
Thank You ❤
Hi Abhishek
Thanks a lot for your way of explanation.
Could you please share how to upgrade ArgoCD CRDs without impacting existing CR in k8s cluster
Thank you ^^
Hi Abhishek, your videos are super helpful. Thanks a lot. can we please have video on Istio ? Thanks a lot in advance.
bro u have vast amount of knowledge on K8s which is quite rare in the market right now...if u make extensive course just on K8s Admin+Development it'll be a very big move...I'd like to purchase such course if u have a plan to do so..
Thanks Sagar, I will let you know if I have any plans :) .. Follow me on Telegram.. I will post updates there once I decide
@@AbhishekVeeramalla sure
Hi Sagar I'm also agree .
Thanks
Welcome
Hi Abhishek, I'm interested in the video for creating a custom controller. Apart from that more insights on cncf and contributing to it, as I'm enthusiastic for contibuting and also work remotely.
Thanks a lot for the video. Really liked it.
I would like to request you to create a video on “how to create a custom k8s controller with operator sdk”.
Thank you so much 😀, sure noted
fantastic video 🔥Done with day 40
@AbhishekVeeramalla, for doubt clarification, when you mentioned watchers(deployment, service watchers) several times towards the end from @timestamp 26:00, you actually mean controllers still right? Thanks for always delivering exceptional contents.
Hi bro, based on my joson template it creates, delete and update the objects .example In the past json template contains one object after some days I will remove the object from that template based on that automatically the controller can do .?
WHat i understood here is apart from k8s default resource and object ,what other services and tool support we can assume as CRDs (like - argocd ,istio,helm ) .Correct if i am wrong .
Thanks Abhishak for awesome videos. They are very informative and easy to follow, may I kindly ask if you have any plan to have tutorial about APIs? It’s a broad topic and used everywhere
Thanks and sure
Looking forward to that 😊
Hi bro your way of explanation is fantastic and I want you from videos regarding Argocd based on the users request only and thanks for kubernetes tutorial I learn lot of things 🙏👍
There is a complete playlist on argocd
@@AbhishekVeeramalla ok bro👍
Hi Abhishek, please do a video for go languag as well
Hi Abhishek,
can you suggest here, like we installed istio via helm and its controller so related CRD and controller installed (i think its a simple installation) but if we would like to write our own crd as per use case then how we can do?, I did not see how we can see api version, endpoints etc.
Hi Abhishek which language i should learn (golang/python)?
Hi, Abhishek
At 36.10 to create namespace istio got an error
Error from server (Forbidden): namespaces is forbidden: User "deepak-hat" cannot create resource "namespaces" in API group "" at the cluster scope
Abhishek is istio majorly used as service mesh or as load balancer? I'm bit confused like how exactly the service mesh is implemented at production level like what use cases does it has
It's more of a service mesh for East West or service to service secure communication.
But it injects a side car container which Envoy proxy that can help you as a load balancer as well but istio is popular to mutual TLS .. secure service to service communication
I am working on argocd in minikube with kubectl...in argocd git repo adding I am getting x509 error while adding repo in ui and in pod when I try to clone I am getting CAfile no and Crtfile no...I tried many possibilites in internet, but nothing resolved it.....
Anything I am making
Git cloning is working in minikube ssh also but only argo server it not
Where is this git repo hosted ? Argo CD has GitHub keys added by default.. so you should not get any error there.
Nice Video.
Do you suggest any Good CKAD courses if you have something on top of your head? could be from anywhere(udemy or youtube etc)
I am not aware of it Jay
@@AbhishekVeeramalla thanks man
Hi Abhishek,
Could you please make a complete video on golang. So that we can write or contribute to CNCF.
It can be done in 1 video
What is Helm chart in K8S Sir, Can you please make dedicated video on it, it is also 1 of the most asked question in interview...
There is already a video on the channel .. please check
@@AbhishekVeeramalla Thanks sir..got it..
@@AbhishekVeeramalla please also make video dedicated to sonarqube only
Please make a video on Controllers using GoLang. Please explain with examples
I recently uploaded a video on kubernetes operators.. pls check
@@AbhishekVeeramalla Thank You, I am very regular with your videos. Getting to learn a lot
Abhishek - you need to have better graphic to make slide mode interesting rather than creating manually .. this will improve quality of your presentation .
Thanks for the feedback.. unfortunately, I dont get time most of the times due to my office work but I will try
@@AbhishekVeeramalla - K8s is good field and lots of attention , so your session will surely attract good views, you can hire a freelancers to do video editing for you and they will relaunch your sessions with modified graphics which will be of professional as your explainations are nice . all the best
@AbhishekVeeramalla Hi Abhishek, No one else could explain this difficult topic so damn well, it is a pleasure to have you give us education free when I am currently searching job and i am still in the completion stage of AWS and Kubernetes projects and practical hands-on, do i have to prepare the troubleshooting as well as i feel so overwhelmed now with aws, Kubernetes altogether and i have less time for bagging a job, i have set a target to myself by end of may i have to land a job so what would be your recommendation? should i just focus on the aws and kuberentes playlist now and later troubleshooting as this video did help me understand better with wrong image issues and how to debug as it was correlated. But now in short span of time do i have to include this also? kindly help me here with your suggestion please
Yes you should complete aws playlist after devops zero to hero 👍
@@AbhishekVeeramalla Thank you for your response , it means i can watch the troubleshooting of k8s playlist later? and also as you mentioned in this video, yes if you teach Go-lang it would be excellent for us.
@@anur642 have you secured the job?
Hi bhaiya, u used adding feature or adding API at the same time so what does the term API actually means here and how is it same as adding feature please answer )
Ok, When you add a new resource type to Kubernetes, you are actually adding a new API
@@AbhishekVeeramalla i got that but please can u explain API in simple words for me once
ok, simple, for example
There is a user called srk in facebook
You can get the user information from browser using
facebook.com/srk
but this information cannot be used by other applications.
So Facebook provides an API called
api.facebook.com/srk
When u access this you will get information of user srk in json format that any other application can use.
@@AbhishekVeeramalla ohhhh okok got it, thanks a ton GOAT ❤️
Abhishek bro subject and concepts u r telling very good with good examples, but while ur explaining theory part u r reading very speed, even to listen and understand its getting bit dificult to us, can you please little slow while speeking pls it would be very helpful again, Thank you for ur content
Ok sure. Thanks for the suggestion
Hai Abhishek, I just want to what exactly Argo CD means in K8S. please share a link to get more details about Argo Cd.
Thank you
argo-cd.readthedocs.io/en/stable/
Thank you
ARGOCD is a CD tool which works on the concept of GitOps. GitOps simply means that our source of truth or the manifests which we have written is deployed on our cluster. Hope It helped you in anyway.
Thank you Rohan
Hi, Does anyone have experience on working with CRDs if so can you share your scenarios please....
I will try to make a video on this in future
openshift tutorial from Redhat
sandbox needed
sir can we expect a video about OPERATORS in upcoming sessions??
Yes
@@AbhishekVeeramalla thank you
@@AbhishekVeeramalla operators videos in details please
When I install kubetl and minikub....local host 8080 refused... could you please help me
Bro, no one will answer such questions in the comments of youtube, don't you have google option,chat gpt?
Your Kubernetes cluster is not started .. start the cluster
Please do a master classes bro like end to end of devops with one cloud and finally we want expecting job ready classes(like shubham bro)
Check if you are the authorized user in kube config file
7:40 to 15:00 is the actual use of CRD
Thanks
Can you make a kubernets full contain video it use full all 👋
I have made close to 10 hrs of content on Kubernetes in this Full DevOps course. It will difficult for people to watch this in one video
