미들웨어는 두가지 특정한 종류의 HTTP 요청에 응답합니다...

### CORS 사전 요청

`Origin` 및 `Access-Control-Request-Method` 헤더와 함께 전송하는 모든 `OPTIONS` 요청입니다.

이 경우 미들웨어는 들어오는 요청을 가로채 적절한 CORS 헤더와, 정보 제공을 위한 `200` 또는 `400` 응답으로 응답합니다.

### 단순한 요청

`Origin` 헤더를 가진 모든 요청. 이 경우 미들웨어는 요청을 정상적으로 전달하지만, 적절한 CORS 헤더를 응답에 포함시킵니다.

ControlPlaneKubeletLocalMode feature gate. It can be used to tell kubeadm to use the local kube-apiserver endpoint for the kubelet when creating a cluster with "kubeadm init" or when joining control plane nodes with "kubeadm join".  The "kubeadm join" workflow now includes two new experimental phases called "control-plane-join-etcd" and "kubelet-wait-bootstrap" which will be used when the feature gate is enabled. This phases will be marked as non-experimental when ControlPlaneKubeletLocalMode becomes...
