Bring a laptop to follow along with this interactive session as we learn how Admission Controllers play a critical role in securing Kubernetes APIs. Attendees will gain hands-on experience using the core Kubernetes APIs, will develop a clear understanding of the architecture and design of the control plane, and will learn how to extend Kubernetes using api aggregation and CustomResourceDefinitions. By the end of this session, attendees will be able to implement basic input validation and testing of webhooks for the Admission Controller.
