Memento Mori

I just passed the CNCF (Cloud Native Computing Foundation) CKA (Certified Kubernetes Administrator) exam. Here's some information about how I prepared for the exam and a few tips for people interested in taking the exam. Starting From Scratch For folks who are totally unfamiliar with k8s, edX offers a free, self paced course, which is a great place to start. There's also a list of online training available in the official k8s docs.

Adequate I bought and recently read The Kubernetes Book, and it was not great, but also not terrible; it was just OK. Pros It's pretty cheap (~$12.00 on Amazon at the moment). It's a decent whirlwind tour of Kubernetes. Nothing goes very deep, but the concepts presented are accurate. The book introduces different deployment types (minikube, single node, and your basic HA/PROD design), as well as building blocks of Kubernetes. The introduction of the API, Pods, Replication Controllers, Replica Sets, and Deployments are all easy to follow and describe them in sufficient detail through simple examples.
