Building Kubernetes controllers and custom resources can be complicated. In this session, we’ll introduce you to building Kubernetes controllers and mutating/validating webhooks using Pepr with Pepr Dungeon Crawl as a way to demonstrate and explain the fundamentals of controllers. We'll also delve into how to create custom resources.

Using a modified version of the classic roguelike dungeon crawler Brogue, where in-game monsters are represented by deployments in the cluster, you’ll see how Pepr simplifies the process of building and implementing validating and mutating controllers, and creating custom resource definitions.

We’ll use Pepr as the Brogue dungeon master to modify both the Kubernetes cluster and the game state. You’ll learn about controllers and webhooks as Pepr and the related Kubernetes Fluent Client interact with both the cluster and the game state.
