Best Tutorial ever. Please do you have any plan to upload any video for CKS Kubernetes Security?
Thanks
thank you. definitely, we will release that also
Thank you so much for this! I just passed the CKA basically only using this video. I can confirm knowing these practice questions is still enough in June 2024.
How do the questions differ? especially which questions did you find similar but different?
Congratulations 🎊
Congratulations , My exam is in the middle of June. Please what your advice
@@wiembelhadj practice well, do not panic in the exam, practices with documentation , all the best
@@kubernetesway Thank you so much for the great video, I cleared the Exam yesterday
Hi Sir. I just cleared my CKA exam with 92 score. Thank you so much. your videos helped me a lot.
@@v.reddybhaskar1473 congratulations 🎊
Hi bro plse guide me bro
@@dhananjayaraju-c7i please share your email ID. I will share the references.
@reddy, please share your emails address, can you help to share exam question
container id is also mentioned in pod description can we use that ? for Q22
yes
for question 25, do we need answer it using podAntiAffinity? or just cording the node is enough?
yes, since they are not mention anything in the question so we can use cordon, other wise they may mention in the question like " do not cange any settings in the cluster " l, and also check the marks ,if the question asking for lower marks then probably they are looking for to answer the question through cordon.
Is it possible to use the text search feature during the exam? When I took the CKAD, I didn’t notice a text search option available in the browser. My second question is, will I get disqualified if I mistakenly click on the discussion link instead of doc link?
am not sure about discussion links,
The best video covers CKA, well explained and fully coverage for all the topics.

Thank you so mucha 🎉❤ ur the best

Question regarding un-schedulable worker node and rescheduling all the Pods... What if the POD is volume Mounted with secret or ENV variable but not with Empty_Dir {}. How to reschedule the Pods to different node?
that much difficult question they will not ask in the exam, but I will update that scenario in our Udemy course, thank you
Kubernetes v1.27 was released on 11 Apr 2023 It has reached EOL on 2024-06-28. Regardless this video is an outstanding and extended walk through on the CKA Exam.

Thanks so much @kubernetesWay for putting this together. This has been super helpful to me while preparing for the CKA. I have one request, can you please do something similar for CKS? Something like Certified Kubernetes Security Specialist (CKS) Practice Exam (mock questions)? We will all appreciate this.
thank you , definitely we will consider that
Hi Nikhil,Do we need to choose CKA platform to practice your questions in killerkoda?please suggest
@@sandeepvemu794 no need , u can make environment even in u r laptop,
@@kubernetesway so we can use not mal playground as well in killerkoda.Why I got this doubt is I see your questions have already created manifests and other commands for few questions
@@sandeepvemu794 you have to make the scenario before answering, most of the scenario are simple, u can make with out much efforts,
@@kubernetesway sure.will practice as many times to master
Hi, in the Network policies, you have used pods for app, web and db.. what images are you using for them, respectively?
hi, i used Nginx for aapp and web pods and Mysql for DB, i posed yamal files on my github , u can use that for making scenarios, github.com/kubernetesway/CKA
Q8: I think that there the pv and pvc were not bound. A "provisoric" pv was created with the pod. No connection between web-pv and web-pvc. Thank you for your work!
yes, some viewers are reported this issue, i will fix and release it on my new series, thank you for your review
Hi, I am getting this error when solving question 10 related to network policies : Trying 192.168.1.9...
telnet: Unable to connect to remote host: Connection refused
command terminated with exit code 1
i will share the yamal files , github.com/kubernetesway/CKA-Series/tree/main/29
Hey there, Thanks you for your efforts in making us practice this exam , I have successfully passed the CKA exam, Much appreciated !!

☑ CKA Challenge Check 4: Troubleshooting
The web deployment in the v8xoge namespace is supposed to be exposed to the Internet by the web service. However, requests from the Internet do not reach the deployment's pods. Resolve any configuration issues so the requests sent to the service do reach the deployment's pods. Do not delete any resources to solve this challenge.
Can you please help me to solve the above challenge?
labels all are perfect? If so then ingress needed to be apply, can i get more details
Please chec kthe below 3 points .
1, Check the Service Type, If it's of type ClusterIP, it won't be accessible from the internet. You'll need to change it to LoadBalancer or NodePort.
2,Verify the Service Selector, Check if the service's selector correctly matches the labels on your deployment's pods.
3, Review Network Policies, If there's a policy blocking traffic, you might need to modify it to allow ingress traffic from the service.
Nice job! Just wondering, what is the difference between this video and the one from Udemy? :)
in udemy we will update new scenarios every week
thanks for the efforts, i just get my CKA certification ❤
congratulations
How do insert sidecar to existing pod, running with container that has volume mounted to path that is in the ENV Variable. For example,
Existing pod:
Name: some name
Image: some image
env:
- name: LOG_FILENAME
value: /var/log/big-corp-app.log
Sidecar: Insert sidecar in the existing pod with below details:
image: busybox:1.28
command: "tail -n+1 -f /var/log/big-corp-app.log"
Use a Volume, mounted at /var/log
Make the log file big-corp-app.log available to the sidecar container.
How to answer this question?
let me check
hi, i could not find a big difference between the sidecar question that we discussed in the video and what u asked, or can u share the full question? then we can help the students. thank you
I love your video
just a small comment on the Q14, I think you are wrong, kubectl get nodes -o jsonpath='{.items[*].spec.taints}' output does not indicate that the control plane is unschedulable.
it just returns all of the taints available on all of the nodes..
also even with that taint existing , if the toleration is provided, the workload would be scheduled..
the CKA question is bit malformed and tricky
Hello, the response provided is accurate. However, I've forgotten the exact wording of the original question. Nevertheless, if you encounter a similar question in the future, you can certainly find the answer using the following command
sorry I disagree.. an accurate command would be like `kubectl get nodes -o=jsonpath='{range .items[*]}{.metadata.name}{"\t"}{.spec.taints}{"
"}{end}'` @@kubernetesway
thankyou, i will update this in our course, @@AmineBenAmor-rz5lb

Q10: Which image is used and how does the deployment look like for 3 applications frontend, application and backend please?
Hi, You can use this yaml files for making scenarios github.com/kubernetesway/CKA-Series/tree/main/31-d
@@kubernetesway Thank you very much, it worked now, due to some reason when I configure nginx with different port, it doesn't work. It still accepts traffic on port 80.
1h46'14" don't see how you came to have node01 with error. In this case, how to create node01 and join the cluster. Thank you for your explanations.
in the question we can see they are asking to join node01, so simply we can ssh to node01, most of the time kubelet service may not started in node01, and that will be the only troubleshooting you need to do in node01.

@kubernetesway not exactly, just same concept asked in a different way
Just received the CKA certificate after finishing the test successfully. Your videos helped a lot! huge thanks 🙏🏻👌🏻👏🏻

Unable to telnet in Q10. which image did you use and how the deployment yaml look like?
The best youtube channel about k8s =))
Thank you
@1:54:57 how you know dbpod port?
Sorry for the delayed reply. That’s a good question. In the exam, you don’t need to check connectivity to all pods, but for the demo, I have to show you whether the pod has a connection to all other pods, since it is a db pod i assuming this is listening in port 3306,
Thanks Nikhil bro, I have cleared the cka exam today
Congratulations 🎊
Congratulations on your exam! My exam is this week. Do you think practicing 30 questions is enough?
Thanks a lot sir🙏. One more thing to update you that there are more questions which I doing it manually. I request if you could please update the yaml file from question 11 till 30 where they are required.
i will update it soon..
@@kubernetesway Thanks a lot I have an CKA exam soon.
Hi if you could please update the yaml file from question 11 till 30
@@kubernetesway Hello Sir, if possible please update the yaml files from question 11 till question 30. Its little bit urgent. 🙏

Was aske to create PVC and class path was provided. I checked for PV, but there was none. So I created PVC using class path and PVC was in bound status. Should I have created PV?
are you in right cluster? I would check the work after pvc is created and it should be in 'Bound' state. A PV should be there first before creating PVC as the name Persistent Volume Claim says claiming a storage from PV.
This is storage class question, thats why there was no pv that time.
Thank You ! Much Appreciated !!!!!!!!!!!

@24:56 / 3:43:54, Metric Server not required to be installed for hpa to work or is it enough to crack the question without installing? Nice content i must commend
metric server will be in the cluster ,The metrics server collects resource usage metrics from each node and makes them available to the HPA controller

hi @nikhil i didnt the network policy question - 3 why we use egress there? web to service should be ingress ?
hi, as per the question we have to restrict the connection from web pod to other pods, and only allow connection to service pods, so we need to use egress service pods, so web pod can only connect service pods

ETCD question with below path file provided. I did not get chance to attempt this question since this doesn't look like ETCD backup. Seems like question was to create secure connection. Do you know how to answer this question?
/etc/kubernetes/pki/etcd/peer.crt
/etc/kubernetes/pki/etcd/peer.key
/etc/kubernetes/pki/etcd/ca.crt
hi, can u share complete question?
I do not remember the complete questions.. but I know it was related to ETCD.. and peer.key and peer.crt was provided instead of server.cert and ca.cert and server.key
ok, let me check@@dhuntay
@@kubernetesway Thank you for your videos and it really helped me to clear many questions in the exam unfortunately I wasn't able to clear the exam and I got 65% .I have a retake so I will again go through videos and practice.
I also got same question in exam. In this type of question should we take peer keys and certification while backing up or should we take as per documentation? Can you tell me how to resolve this kind of question?? the question was need to back up and store it to the location(they have given random-I couldn't recall) but while restoring they asked to restore previous and current backup? They haven't provided path for restore. instead they mentioned new backup var/lib/etcd/etc-backupsnapshot.db. No previous backup found and which path should be mention in --data-dir?? somehow etcdutl and etcdctl wasn't working for restore.
@@vikramvaroo145 in my video u can find two videos realted with Backup and restore, second video is exactly the same model , can u check it that ?
