    Certified Kubernetes Application Developer (I PASSED!)

    As of January 18, 2021 I am a Certified Kubernetes Application Developer!

    I scored much higher on my 2nd attempt. I attribute that to the following:

    • My test environment is MUCH better. I moved to a new home and I had a guest room that I prepared a day before the test. Had a comfy chair and all 🙂
    • I took the test at 9am in the morning. I did not have any interruptions at home compared to last time.
    • For a few months, I spent about 30 minutes to 1 hour each day on kubectl commands and documentation. 1 week before the test, I did an hour a day with imperative commands.
    • I made bookmarks to knowledge gaps I had with Kubernetes to the Kubernetes official documentation.
    • I have Kubernetes applications in production.

    Resources I Used

    I used the following materials that helped me with CKAD:

    • CKAD Exercises by dgkanatsios/CKAD-exercises
      • I did this, at minimum, 30 minutes a day for a couple of months.
      • You need a complete mastery of the kubectl without needing to look up commands often during the test.
    • Udemy CKAD with Tests by Mumshad Mannambeth
      • 3 months before my 2nd test attempt, I went back and watched several videos to revamp some of the knowledge gaps I still had with CKAD.
    • CKAD Labs by Mumshad Mannambeth
      • The Udemy course provided by Mumshad, he created labs to help aspiring CKAD professionals 🙂
      • I went through many of the labs and even revisited some of the labs to fill in my knowledge gaps.
      • There are some practice tests in here that can help you master the kubectl much more efficiently.
    • kubectl Cheat Sheet from Kubernetes Documentation
    • Kubectl Reference Docs from Kubernetes Documentation
