In this video I cover the how I passed the Certified Kubernetes Administrator (CKA) exam giving practical examples, tips and covering important topics that will help you get through the exam. This is an exam guide but does not fully cover all details related to the exam and as such you must still review the pre-exam instructions prior to taking the exam.

Thank you for this video, man. I just got my CKA badge today.

[@jmmtechnology4539]

That's awesome man congrats!

[@booyaadotorg]

Thanks for this helpful video you've provided some great pointers as well useful tips (bash help aliases and functions).

[@aviadhaham5523]

Great vid man! Just so you know, to show the example of the `kubelet` status, you could have just `minikube ssh` or just ssh manually to minikube node, and then check (treated as a control/worker node).

[@diegonayalazo]

Amazing description. Thanks

[@user-ji8sw5sw8y]

Just awesome mate !! kudos

[@LeightonSpicer]

Thanks John - Great video. Just need to put some effort in now.

[@rawhidewolf]

Yes. This was helpful. There were some very small things I learned that will save me time and frustration.

[@jmmtechnology4539]

Thanks!

[@Explore_with_Azizul-maqsud]

Great and AWESOME video... but, Bash commands are seen so much smaller... please change it full screen! Thank YOU

[@ashermanangan]

thanks a lot ~ greetings from Philippines

Thanks man, subscribed!

[@jmmtechnology4539]

Thanks!

[@randayho]

great idea on the function to change to the namespace. i'm also going to put an alias called "cn" so i can see the current namespace i'm in, i think that would be helpful also

[@danishsiddiqui7321]

VERY HELPFUL VEDIO !

[@Insane_Kane]

At 33:17 you edit a pod and then when it doesnt work make a yaml copy of that you delete stuff from and edit. When you do a "k edit" and it fails, it generates a copy of the file WITH the changes automatically (filename is in the console). You can then just do a "k replace" using that exact file with the --force parameter

[@jmmtechnology4539]

Nice one, I did not know that!

[@sergiorivera4505]

nice that one > k replace --force -f /tmp/.yaml

Thanks!

[@pranilkharche320]

Thanks Buddy for the video, I use Nano Editor as my main, can you please share the same with using nano instead?? was PSI too bad for you ? How did manage giving the exam inside the Remote OS and please advise dos and don'ts while giving exam on PSI.

[@yunusemregormus201]

thanks for fabilous content

[@OrionPronk]

Thanks for this great video. If I could make a suggestion, please increase your terminal font size for recordings. It's a bit hard to read with a Macbook and hard to distinguish a = from a : even when squinting my eyes :D

[@kbv3853]

Namespace function is very smart idea. Nice video. Keep it up.

[@jmmtechnology4539]

Much appreciated man!

[@iagogarcia4012]

I came specifically to this video to thank you. I commented a few days ago in another video that I used most of your videos to complement my studies and it worked! I reached a score of 79 on the test. Thanks and keep your good work here sir

[@jmmtechnology4539]

Congrats Iago! Glad to be of help :)

[@bhagiyarajmahesh8972]

I always make errors in the yaml structure & indentation. Kindly post a video on the same. It'll be helpful.

[@retinizer7702]

Great vid, definitely deserves a sub . Just one advice zoom in on terminal a bit

[@jmmtechnology4539]

Will do man. Thanks!

[@narigina6414]

amazing content

Thank you!

[@babettek8050]

GREAT VIDEO BUT UNFORTUNATELLY COMMAND THAT YOU ARE TYPING ARE NOT READABLE ENOUGH. THANK YOU

[@VictorMoreno-xd7en]

Great!! good stuff. Pity there is noise in the video. thanks so much. I like the plural trick. But attention with env is singular! :) thanks

[@jmmtechnology4539]

Thanks Victor! But yeah my apologies for the background noise.

[@prasantchettri133]

kilershell has texeditor we can from native os but I could not find one during the exam. It would be nice to have texteditter other than vim for making correction

[@ramdasnair5655]

Thank you for your video. Did you have use for jq for json processing?

[@jmmtechnology4539]

Nope, jsonpath is enough to answer the questions for json processing. kubernetes.io/docs/reference/kubectl/jsonpath/

[@hulksmashgreen123]

great video I was wondering would this work as a function to get the snapshot status with ess as a alias through a function definition: function ess () { etcdctl config set-context --current --snapshot status=$1 }

[@jmmtechnology4539]

You certainly could, it may not be a command you're using frequently enough in the exam to justify the up front effort of creating a function but that depends on your experience.

[@PlacidoYT]

Hey man, how's the vm? Is it laggy? I do utilize k8s doc most of the times and copy codes from there.

[@jmmtechnology4539]

The VM works nicely once your internet connection is good. If you're below 15Mb/sec you might start to run into lag.

[@nailvalimatov4980]

Great video. thanks. But i encountered one problem after creating alias k. So, with kubectl I can use bash completion but with k bash completion didn't work for me.

[@jmmtechnology4539]

Ah I see, in that case this may be a trade off that you have to consider personally and determine which solution is best for you.

[@landryja1893]

Nice tips! How do you access the terminal on exam day? Is it there on the screen or do you open a specific window for it?

[@jmmtechnology4539]

Thanks! You can search for terminal and open it up. It also may already be open when the exam starts.

[@landryja1893]

Just one more question: How do you search within a page on kubernetes documentation? Does Ctrl F work?

[@jmmtechnology4539]

@@landryja1893 yep!

[@landryja1893]

Thanks!

[@EduardoSantanaSeverino]

Thank you for the video. I am about to take the CKAD, and I am looking for some preparation advice. Also, is it more difficult than the CKA? Or not? Do you have any udemy courses that would target the CKAD? I see that you have in the description the udemy course for CKA. I'm wondering if that one would serve my needs to pass the CKAD. Thank you in advance.

[@jmmtechnology4539]

Hi Eduardo, based on my experience with the CKA version I would recommend this course: www.udemy.com/course/certified-kubernetes-application-developer/ although that's not to say there aren't many other good resources out there.

[@devops-network]

Hi can u share tips related to network policy. Generally these questions are really polished and hard to interpret.

[@jmmtechnology4539]

Hey! I have a video on Network Policies here: kzbin.info/www/bejne/nZfCeJeEZdmmoLs. That will give you a conceptual understanding of how they work. When it comes to tackling the questions it's important that you're very familiar with the docs. In the exam you will be able to copy an example from the docs but it's important you're familiar with the structure of the yaml in order to modify to suit your needs. Make sure you know how to select the pods that will have the NetworkPolicy applied to them (ie podSelector) as well as the different ways to select the traffic source that will be allowed to those pods (podSelector, namespaceSelector, ipBlock etc)

[@devops-network]

@@jmmtechnology4539 Thank you for reply. I will check the video.

[@shmuelsigler2918]

im gonna use my laptop for the exam, do you know if i can use 2 monitors? great guide, i realy found it helpful.

[@jmmtechnology4539]

As far as I’m aware additional monitors are not allowed but you should double check that on the pre exam guide once you have purchased the exam.

[@prasantchettri133]

@@jmmtechnology4539 you will have to shut the laptop clamshell and use external camera to get pass the monitor limitation

[@jesuszagal2737]

please, make a video how to pass the Certified Kubernetes Application Developer (CKAD) Exam 🙏

[@jmmtechnology4539]

I'll have to complete it first!

[@user-iv8kp7rv7r]

Is it possible for freshers to take this exam ..? Or prior experience is necessary.

[@heavenchloe]

I'm hoping to take this this year, i saw that the exam was open book, is that correct?

[@jmmtechnology4539]

Partially, you will have access to the official kubernetes docs during the exam, you're not allowed to use other sites.

[@mdaverde]

Into these videos! You sound like you're in an airplane on this one though

[@jmmtechnology4539]

Thanks man, yeah my bad I left a fan running in the background, didn't realise until I had it recorded.

[@alexnovik]

do not do etcdctl snapshot status!!!! it will corrupt your snapshot

[@nohandsignal]

Do u got any dumps ??

[@jmmtechnology4539]

What do you mean?

[@nohandsignal]

@@jmmtechnology4539 means questions of previous standard exam

[@jmmtechnology4539]

@@nohandsignal no, however when you buy the CKA you get access to a practice environment called killer.sh, these questions are a good representation of the actual exam (but a bit more difficult) and you are also supplied with all the answers for these questions.
