This lab provides practice scenarios to help prepare you for the Certified Kubernetes Security Specialist (CKS) exam. You will be presented with tasks to complete, as well as server(s) and/or an existing Kubernetes cluster to complete them in. You will need to use your knowledge of Kubernetes to successfully complete the provided tasks, much like you would on the real CKS exam. Good luck!
