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.
  kubeadm init phase bootstrap-token
```
