Overview

Package v1alpha3 is the API (config file) for driving the kubeadm binary. Some of these options are also available as command line flags, but the preferred way to configure kubeadm is to pass a single YAML file with multiple configuration types in with the --config option.

kubeadm defines several configuration types: * InitConfiguration * JoinConfiguration * ClusterConfiguration

InitConfiguration and JoinConfiguration cannot share a single YAML file, however it is expected that InitConfiguration and ClusterConfiguration will share a single YAML file.

 A fully populated example of a single YAML file containing multiple
 configuration types to be used during a `kubeadm init` run.

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.
