Ready for the real environment experience?
Failures are inevitable when running large clusters. This Lab teaches you how to detect, diagnose, and remedy a variety of Kubernetes failures at the network, node, control-plane, and application levels. You will use tools included in Kubernetes, such as kubectl, as well as a variety of Linux operating system tools like systemctl, journalctl, ss, and openssl to build a comprehensive Kubernetes troubleshooting toolkit.
