This lab provides practice scenarios to help prepare you for the Certified Kubernetes Administrator (CKA) 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 CKA exam. Good luck!

replicas.- Create an Ingress That Maps to the New Service
