Description

Cluster component failures are inevitable when running large clusters. This Lab teaches you how to detect, diagnose, and remedy Kubernetes cluster component failures. You will use tools included in Kubernetes, such as kubectl, as well as a variety of Linux operating system tools like systemctl, journalctl, and ss to build a comprehensive Kubernetes troubleshooting toolkit. In addition to reacting to failures, the Lab points out some ways that you can proactively reduce the chance of failures when working with Kubernetes.

This Lab is valuable to anyone working with Kubernetes, but the content has been prepared considering topics described in the Certified Kubernetes Administrator (CKA) Exam Curriculum. Completion of the Lab will help you get hands-on experience, which is essential for passing the CKA exam.
