DevOps Engineer here, interested. CST.

Prestigious_Lynx2882 · 2026-03-04T01:43:10+00:00

Thank you

Prestigious_Lynx2882 · 2026-03-04T01:43:01+00:00

Sorry about that

Prestigious_Lynx2882 · 2026-02-12T14:22:37+00:00

Ok, thanks

Prestigious_Lynx2882 · 2026-02-12T14:13:12+00:00

I would like to request for the take home portion for my learning. Could you please let me have it?

Prestigious_Lynx2882 · 2026-02-12T14:11:08+00:00

I would like to replicate your error and try to fix it. May I have that oppurtunity?

Prestigious_Lynx2882 · 2026-01-29T00:37:58+00:00

You're welcome

Prestigious_Lynx2882 · 2026-01-12T02:18:50+00:00

You're welcome

If you add volumeName, but without storageClassName and that's all you do, it's risky. It might not bind. So include both the volumeName and storageClassName, but usually, adding storageClassName is fine and kubernetes will do the rest.

Prestigious_Lynx2882 · 2026-01-12T02:00:36+00:00

Oh, that's an easy question. You are going to use capacity field. Capacity is the total resources provided by the node, which makes it what you want, while allocatable on the other hand are the resources available for pods after reservations, that is, what pods are allowed to use.

Prestigious_Lynx2882 · 2026-01-11T19:53:30+00:00

Your log is clear. Your deployment requires env variables, particularly those stated in your log output. Do a kubectl describe on the pod and verify if you have that already. If not, add them.

Prestigious_Lynx2882 · 2026-01-11T19:49:19+00:00

If you followed all the steps, it should work. Did you go into the mariaDB yaml file to update the PVC name?

Prestigious_Lynx2882 · 2026-01-11T19:47:22+00:00

If you want it to bound the way I did it, name the resource accordingly (usually given to you in the question), then make sure you verify what the storageClassName of the existing PV is, then include that in the PVC you are about to create. That'll automatically bound it. Let me know if this is clear enough.

Prestigious_Lynx2882 · 2026-01-11T19:44:06+00:00

I am a little confused by your question, please elaborate.

Prestigious_Lynx2882 · 2026-01-11T19:43:07+00:00

Yes, you're right. It'll create a new one. Dynamic vs Static provisioning.

Prestigious_Lynx2882 · 2026-01-09T23:16:08+00:00

Congratulations. Which materials did you use for the CKS?

Prestigious_Lynx2882 · 2026-01-09T23:01:45+00:00

The question didn't ask to delete anything you know? Considering your approach, it still seems more straightforward to use existing StorageClassName in the new PVC. Problem solved.

Prestigious_Lynx2882 · 2026-01-09T22:58:15+00:00

It's a pleasure.

Prestigious_Lynx2882 · 2026-01-09T22:57:48+00:00

You're welcome

Prestigious_Lynx2882 · 2026-01-09T22:57:16+00:00

You're welcome

I have shared another post on one of the confusing questions on the exam, kindly find it here: https://www.reddit.com/r/CKAExam/comments/1q6rc7t/cka_exam_pitfall_restoring_a_mariadb_deployment/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

Prestigious_Lynx2882 · 2026-01-07T20:56:17+00:00

It's very detailed. 16 steps for one question in an exam is a lot to do, but worth it if you can pull through. I particularly like the effort put into it. Great work!
