Kubebuilder: SDK for Extending Kubernetes
summary
Kubebuilder scaffolds a full operator project (APIs, controllers, webhooks, Makefile, Dockerfile) and uses controller-runtime libraries and code generators to produce CRDs and deep-copy/validation code. Demo creates a BoundedDeployment CRD with a replica field, a mutating webhook that clamps 10 down to 2, and a controller that creates a Deployment with that replica count; image build, deploy, and test on a cluster complete and the 10→2 mutation plus deployment creation works as shown.
