Overview

Package kubeadm holds the internal kubeadm API types Note: This file should be kept in sync with the similar one for the external API TODO: The BootstrapTokenString object should move out to either k8s.io/client-go or k8s.io/api in the future (probably as part of Bootstrap Tokens going GA). It should not be staged under the kubeadm API as it is now.

Package kubeadm is the package that contains the libraries that drive the kubeadm binary. kubeadm is responsible for handling a Kubernetes cluster's lifecycle.
