apiextensions-apiserver

Implements: https://github.com/kubernetes/design-proposals-archive/blob/main/api-machinery/thirdpartyresources.md

It provides an API for registering CustomResourceDefinitions.

Purpose

This API server provides the implementation for CustomResourceDefinitions which is included as delegate server inside of kube-apiserver.

The apiextensions.k8s.io API types and their generated clients are published in k8s.io/apiextensions-api, which doesn’t depend on the server libraries. The packages under pkg/apis/apiextensions/v1, pkg/apis/apiextensions/v1beta1 and pkg/client here are deprecated aliases of those, except that AddToScheme in pkg/apis/apiextensions/v1 and v1beta1 also registers the conversions to the internal version. See the k8s.io/apiextensions-api README for how to migrate.

Compatibility

HEAD of this repo will match HEAD of k8s.io/apiserver, k8s.io/apimachinery, and k8s.io/client-go.

Where does it come from?

apiextensions-apiserver is synced from https://github.com/kubernetes/kubernetes/blob/master/staging/src/k8s.io/apiextensions-apiserver. Code changes are made in that location, merged into k8s.io/kubernetes and later synced here.
