Certified Kubernetes Administrator (CKA) Study Guide ebook download free in pdf published by Oreilly Media, Author by Benjamin Muschko, released in November 2022 (Early Access).
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 a system 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.
- Learn when and how to apply Kubernetes concepts to administrate a production-grade cluster
- Understand the objectives, abilities, and tips and tricks needed to pass the CKA exam
- Explore the ins and outs of the kubectl command-line tool
- Demonstrate competency to perform the responsibilities of a Kubernetes system administrator
- Solve real-world Kubernetes problems in a hands-on command-line environment
- Effectively navigate and solve questions during the CKA exam
Kubernetes clusters need to be installed, configured, and maintained by skilled professionals. That’s the job of a Kubernetes administrator. The CKA certification program verifies a deep understanding of the typical adminstration tasks encountered on the job, more specifically Kubernetes cluster maintenance, networking, storage solutions, and troubleshooting applications and cluster nodes.
KUBERNETES VERSION USED DURING THE EXAM
At the time of writing, the exam is based on Kubernetes 1.21. All content in this book will follow the features, APIs, and command-line support for that specific version. It’s certainly possible that future versions will break backward compatibility. While preparing for the certification, review the Kubernetes release notes and practice with the Kubernetes version used during the exam to avoid unpleasant surprises.
The following overview lists the high-level topics of the CKA and their scoring weight.
- 25% – Cluster Architecture, Installation & Configuration
- 15% – Workloads & Scheduling
- 20% – Services & Networking
- 10% – Storage
- 30% – Troubleshooting
The CKA curriculum went through a major overhaul in September 2020. One of the reasons why the exam domains have been reorganized and optimized is the new Certified Kubernetes Security Specialist (CKS) certification. For the most part, security-related topics have been moved over to the CKS while the CKA continues to focus on typical administration activities and features.
