Generates bootstrap tokens used to join a node to a cluster
Synopsis
Bootstrap tokens are used for establishing bidirectional trust between a node joining the cluster and a control-plane node.
This command makes all the configurations required to make bootstrap tokens works and then creates an initial token.
kubeadm init phase bootstrap-token [flags]
Examples
# Make all the bootstrap token configurations and create an initial token, functionally
# equivalent to what generated by kubeadm init.
