The ability to administer and monitor a Kubernetes cluster is in high demand today. To meet this need, the Cloud Native Computing Foundation developed a certification exam to establish an administrator's credibility and value in the job market to confidently work in a Kubernetes environment. The Certified Kubernetes Administrator (CKA) certification exam is different from the typical multiple-choice format of other professional certifications. Instead, the CKA is a performance-based exam that requires deep knowledge of the tasks under immense time pressure. This study guide walks you through all the topics covered to fully prepare you for the exam. Author Benjamin Muschko also shares his personal experience with preparing for all aspects of the exam.
This book will provide a beginner with a good introduction to Kubernetes. For someone working with Kubernetes regularly, this book is a good reference for clearing up any doubts on particular topics and filling knowledge gaps. If you're kind of old-school like me, it's worth the purchase when preparing for the CKA exam. But it's one tool to have handy. Don't depend on it alone.
I found the sections on bootstrapping a cluster, etcd backups, networking, and Services the most helpful.
