The path to CKA, and some tips.

Yes, I passed the CKA exam.👍

Since I have already been working with kubernetes for yeas. The way I prepare CKA and the schedule I made might not suit for the beginners. But, still, some of the tips and resources can be shared.

Resources

1. Certified Kubernetes Administrator (CKA) with Practice Tests

I highly recommend this course. It contains the sufficient lecture for the CKA test. Most of all, the hands-on labs have good coverage for the skill you need for the CKA test.

1. Tasks tab in official k8s doc. There are lots of hand-on task in the task tab of official document. And some of them is important for the test.

Tips and advice

1. A least know how to use tmux!
   Your test environment might have a chance to be extremely slow.
   There was one question that took me a lot of time to wait for the command execution to be finished.
   At the first attempt, I wait for about 5 mins. But the command still stuck there. I have no choice but to kill that command and skip to another questions. When I finished the rest of all question, I still have about 15~20 minutes. So I typed the same correct command again and wait for the execution to be finished. But in the end, those 15~20 minutes is not enough.
   If I know the basic usage of tmux, I can keep that command being running, in a meanwhile, I can double check my answers.

2. Get familiar with kubectl run
   Get familiar with this command, it can generate yaml templates for pods, depolyments. And save you lots of time.
