# kubeadm-init-phase-bootstrap-token(1)

Generates bootstrap tokens used to join a node to a cluster

Eric Paris Jan 2015

## NAME

kubeadm init phase bootstrap-token - Generates bootstrap tokens used to join a node to a cluster

## SYNOPSIS

**kubeadm init phase bootstrap-token** \[OPTIONS\]

## DESCRIPTION

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.

## OPTIONS

**--config**=""\
 	Path to a kubeadm configuration file.

**--dry-run**=false\
 	Don't apply any changes; just output what would be done.

**--kubeconfig**="/etc/kubernetes/admin.conf"\
 	The kubeconfig file to use when talking to the cluster. If the flag is not set, a set of standard locations can be searched for an existing kubeconfig file.

**--skip-token-print**=false\
 	Skip printing of the default bootstrap token generated by 'kubeadm init'.

## OPTIONS INHERITED FROM PARENT COMMANDS

**--rootfs**=""\
 	The path to the 'real' host root filesystem. This will cause kubeadm to chroot into the provided path.

**--version**=false\
 	\--version, --version=raw prints version information and quits; --version=vX.Y.Z... sets the reported version

## EXAMPLE

```
  # Make all the bootstrap token configurations and create an initial token, functionally
  # equivalent to what generated by kubeadm init.
  kubeadm init phase bootstrap-token
```
