Lab description

There are many facets to security in Kubernetes. One small oversight can leave your cluster vulnerable to leaking sensitive data, running foreign workloads, and a host of other attacks. This lab shows you how to practice defense in depth in Kubernetes by covering a key security concept: security contexts. Examples of potential exploits from improperly configured clusters are also illustrated followed by guidance on how to prevent the attacks.

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.
