Kubernetes admission controller Part 1

Kubernetes admission controller is critical for cluster security, but implementation is tricky and require real understanding. There are great many tutorials available for the same as well as it is well documented in Kubernetes.io website, but I have seen many misunderstanding and frustrations on the subject, there are certain questions I have received are common, so thought to prepare hands on lab video to answer some of them. It will be 3-part vlogs and contain following topics Admission Controller, Dynamic admission controller (Validating & Mutating), Open Policy Agent, Certificate manager and How to set it up?
