@@IAMDINUTH Hi Dinuth.. Greetings of the Day! Yeah, I performed good on some questions n see need to improve some things. I would like to share my experience n understand if any faults I did or need to know how to better. May I ask you to know if you are able to give sometime to know my exam exp n give suggestions on my faults if any??. Srini.

Welcome !!!

Thank you Deepak 👍🏻

Welcome David. Wish you all the very best for the exam !!! 👍🏻

Thank you Khan. Before hearing what others says about it try it by yourself. I don’t see anything tricky there. Cluster can be a kubeadm based cluster or a cluster created in the hard way. Certificates might not be in default locations. So where to look for certificate and endpoint may change. Endpoints can also be different. So beware. You can check the cli help of etcdctl snapshot restore command to find the parameters to be passed. Try this multiple times. It would never be hard.

Thanks Dinuth!

For the exam, you don’t need to know volume resize/expansion. Kubernetes Persistent Volumes, Persistent Volume Claims, Storage Classes ukposts.info/have/v-deo/faGkqpmrq6-QqZs.html

Exam complexity increases from CKAD < CKA < CKS. Beginner can start with CKAD. CKAD and CKA has around ~80% overlap in curriculum. So you can do CKAD first. Then with little effort covering the remaining 20% you can do CKA.

Yep 😊

Sorry Sachith. I don’t know any local place for CKA lessons.

Hi Eranga, Yes it is allowed and it saves lot of time during the exam. Make sure to bookmark the documentation with the same version of the exam environment.

You don’t need to open multiple terminals. You will be working on a single cluster at a time. One terminal is enough. Use notepad feature if you want to keep some notes for references.

@@IAMDINUTH tmux 's split-windows is another option.

Yes. Make sure bookmarks are from only allowed sites.

1. Did you check whether you ssh to the correct server? 2. Did you check the kubelet pod-manifest-path configuration?

Hi Zareh, No it is not necessary to take killer.sh.

Even before reading the question, copy the context change command and run it. Do it as a practice, otherwise you will end up performing the task in a wrong cluster.

@@IAMDINUTH Thanks! So dont we have come back to where we were after connecting to the cluster given in the question?

If you SSH into a separate server, yes you need to come back to the original server by exiting the SSH connection. You don’t need to do anything like that for the context.

@@IAMDINUTH Thanks a lot!

I didn’t get such an issue. Didn’t you check default $HOME/.kube/config has required permissions or not?

Thank you for the feedback. I’m creating videos to cover each curriculum domain of CKAD and CKA as a knowledge refresher which benefits everyone. Here is the 1st video in that series. ukposts.info/have/v-deo/aXKWoo2RqIWYrn0.html Please raise your question here. I can answer and help you without violating exam NDA. Stay safe !!!

@@IAMDINUTH Thanks Dinuth for the prompt response. I shall note down my queries and ask you one by one. Meanwhile would you mind giving some interview tips. The problem is everyone is looking for experience which is fine from their end, but what about us who are new to it and willing to work in Containerization. Could you please throw some light and share some ideas...!!!!

@@roshansharma3438 That’s true. Everyone is looking for experience. If the experience is not there are few things that you can do to show your expertise. 1. Get yourself certified with CKA, CKAD, CKS. At least one. You should follow the exam materials not just to pass the exam, but to learn every nut and bolt of Kubernetes. If possible try to reach above 90% in these certifications. 2. Outside the exam topics, you need to read what is happening in this domain. Read and watch news, articles, blog posts, best practices, security and more. 3. Write your own articles in LinkedIn or Medium. If you are doing some tryouts, add them to your github and share with community. During the interviews when you are answering the questions take few of them as a reference. 4. There are lot of common K8S interview questions that you can find out with a simple google search. Go through them and make sure you are prepared. 5. Show your confidence during the interview. Don’t give one liner answers. Always explain the concept or the configurations with details. Take every question as an opportunity to show your knowledge. Good Luck !!!

@@IAMDINUTH Thanks a lot Dinuth for sparing so much time. Really means a lot. 🙂. Stay safe..!!

Welcome !!! Stay Subscribed for new videos !!!

Volume in pod.spec has no labels. It has a name. It is not clear what are you referring here.

@@IAMDINUTH i got this question in the exam , after i create the pv and pvc he ask me to mount this volume to the pod with label app:nginx

You need to find the pod with app:nginx label using kubectl get po -selector=“app=nginx” Then get that pod config into a yaml file using kubectl get po [PODNAME] -o yaml > nginx.yaml Then you need to edit the nginx.yaml to mount the volume. Delete pod and recreate with nginx.yaml Watch this video if you are not familiar with above commands. ukposts.info/have/v-deo/aXKWoo2RqIWYrn0.html

Yes

Yes. Go through Mumshaad’s course and you need to practice everything. It is good for a beginner. But it is your responsibility to get yourself comfortable with all domain topics with hands-on. Then go through my free Kubernetes Refresher course and make sure you know everything that I’m discussing here. ukposts.info/slow/PLD1niLkf7lLKYZA68xlaaoid_mrtkPiiQ Good Luck !!!

That’s true and I’m also experiencing the same issue. Most of the technologies are rapidly changing. Based on that certification providers are defining the exam validity period. Agree or disagree; we need to adhere to that.

Certifications hold value on your resume even after they expire. You don't lose knowledge when the certificate expires. A sane person would assume that if you were certified in something many years ago and have worked on the technology for so many years (even if that's not all you work with), your experience has more value than any certificate.

Applications deploy to servers directly is becoming outdated. Latest trend in most of the enterprises is to modernise their existing applications to deploy as containers. Further most of the greenfield/new apps are tends to deploy as containers considering many benefits comes with containerization. So current job market to container orchestration tool such as Kubernetes is very high. Simply search for Kubernetes jobs in google. You can find out more details.

It is recommended to go through Kubernetes the Hard way setup step by step and understand every step. Which will give you a good understanding on TLS certificates and the usage of that in Kubernetes clusters. But you will not be asked to setup clusters in the hard way. But would be useful in troubleshooting questions. Further you need to know the TLS cert and keys in kubeconfig and how to use them to make API calls to api-server. If you are asking the question about Kubernetes TLS secrets, yes you better know it how to create TLS typed secrets too.

@@IAMDINUTH thanks for the swift response. No I'm asking about the certificates itself not the secrets, I'm feeling them tough the TLS certificates generating them it is totally confusing 🥺🥺🥺😶. Thanks for the reply bro...!

I haven’t seen any questions in the exam asking you to create certificates. But even though they asked you don’t need to worry. You are allowed to go through Kubernetes documentation during the exam. Important links and your week areas related documentation pages can be bookmarked and use it during the exam. Check below link and understand it. No need to memorize. If a question asked on this topic open the link copy commands and perform the task. Simple. kubernetes.io/docs/tasks/administer-cluster/certificates/

Do you remember the command you executed?

Hi, Questions are NOT related to each other. You will be working on multiple clusters, multiple namespaces avoid conflicts between questions. Further make sure not to delete any existing resources in these clusters unless you ask to do so as part of a question.

@@IAMDINUTH Thank you for your consideration. I had another question. I have taken CKA course of Mumshad Mannambeth. there is a section in that course about security(certifications in particular). this section was the most difficult one for me. However I haven't seen any question from that topic in the CKA exam... is it necessary to learn that section in depth to be confident in the exam? thank you

Where did you try to create yaml files? You need to understand linux basics as you will not have full permissions by default. Use ~/ and /temp locations where you should have permissions by default without permissions elevation.

@@IAMDINUTH it was a basic -o yaml>pod.yaml command and my expectations was, it should create the .yaml file in ./ but for more than 20mins i struggled with it in the exam until i deliberately logged out from the master node(more like shutting down) then i asked the proctor to help me log in back to the master.

1. Pod can have multiple containers with different images. Check multi container pods video (ukposts.info/have/v-deo/bndomZd4bmODp3U.html) 2. You don’t need to do this in a single command. In the exam you can find the pod name with highest cpu by executing kubectl top po -l app=nginx and manually write the highest cpu pod name to the file. echo "nginx-85ff79dd56-4b9xb" > /path/filename

​@@IAMDINUTH - kubectl top po -l app=nginx --sort-by cpu and store the pod name to file (researching to save the pod name to file using awk, grep or cut)

kubectl top po -l app=nginx --sort-by cpu --no-headers | awk 'NR==1{print $1}' > myfile.txt

@@IAMDINUTH - Thank you

Time is completely depends on your learning skills and dedication. But trust me. It is not that hard when you get into the right track. So start the journey and see how it goes !!!

I never come across with such limit or issue. So nothing to worry. 😊

@@IAMDINUTH Okay sir, thank you very much

I cannot share any exam questions due to NDA signed when taking the exam. Broken clusters, broken nodes, broken applications are very common. You will not get anything beyond the sub bullet points defined under troubleshooting. Shared course materials has enough coverage in all domains including troubleshooting. Do KodeKloud tests again and again until you are fully confident on all areas. At the end everything depends on how experienced you are in solving real issues with practice, practice and practice.

@@IAMDINUTH thanks for the information. Also tell me if I have to ssh any worker node then wht command i would be using? 1) ssh username@IP of worker node will work ? 2) my approach is -- I will take take the External IP of worker node from Kubectl get nodes -o wide but what abt password from where i will get that? Sry to ask such simple question as I am new to linux environment

You don’t need to pass any username. ssh [NodeName/IP] will work. Before the exam, it will show all these institutions.

@@IAMDINUTH One more question, Suppose, they will ask me to create a cluster with two node. As part of it ,We have to install docker and kubelet in all the nodes. Can i copy commands in notepad and use it for all other nodes?

Definitely you can copy anything to the notepad and reuse it.

Sorry. I didn’t get your question. Please elaborate.

​@@IAMDINUTH sorry, I mean this exam is supervised with camera or something like that?

Yes. It is supervised over camera and microphone. Room will be observed before starting the exam. Cannot have any other electronic devices close by. Cannot talk or cover your mouth during the exam. If so examiner will give you warnings.

Yes.

It depends and varies based your learning skills. So you better take the first step in the CKAD learning journey and decide it by yourself.

15 to 20 questions according to the official exam tips. I have seen most of the candidates received around 19 questions. docs.linuxfoundation.org/tc-docs/certification/tips-cka-and-ckad

In 1st attempt.

It is depending on the exam question. If the question is asking to restore to a different location, you need to make sure configs a pointing to the new location. If the question is just asking to restore without referring to the destination location, you have the flexibility to restore to the same data location or a different location with config changes.

@@IAMDINUTH Thanks Dinuth..How to identify which cluster's etcd config file to be changed to new data dir from endpoint details.

In the question you will be given the cluster context change command. So you know which cluster’s etcd config to change.

@@IAMDINUTH Thanks a lot..
