I’ve passed the CKA certification! It’s been a while since I’ve obtained a certification.

As part of Kubecon last year I purchased the exam at a discount. With the upcoming birth of my child, I wanted to make sure to have the certification done before my life is consumed by diapers and bottles. I wanted to share my experiences with whoever may endeavor to take the exam in the future (as much as I’m allowed).
