Kubernetes

Generate the certificate for serving the Kubernetes API, and save them into apiserver.cert and apiserver.key files.

Default SANs are kubernetes, kubernetes.default, kubernetes.default.svc, kubernetes.default.svc.cluster.local, 10.96.0.1, 127.0.0.1

If both files already exist, kubeadm skips the generation step and existing files will be used.

Alpha Disclaimer: this command is currently alpha.
