+// by submitting a certificate signing request, and having it asynchronously approved and issued.

+//  2. serving certificates for TLS endpoints kube-apiserver can connect to securely (with the "kubernetes.io/kubelet-serving" signerName).
+//
+// This API can be used to request client certificates to authenticate to kube-apiserver
+// (with the "kubernetes.io/kube-apiserver-client" signerName),
+// or to obtain certificates from custom non-Kubernetes signers.
