controller-gen

Code generator for Kubernetes controllers and CRDs

Kubebuilder makes use of this tool for generating utility code and Kubernetes YAML. This code and config generation is controlled by the presence of special "marker comments" in Go code.

Controller-gen is built out of different "generators" (which specify what to generate) and "output rules" (which specify how and where to write the results).
