## NAME

kubeadm join phase control-plane-prepare certs - Generate the certificates for the new control plane components

## SYNOPSIS

**kubeadm join phase control-plane-prepare certs** \[OPTIONS\]

## DESCRIPTION

Generate the certificates for the new control plane components

## OPTIONS

**--apiserver-advertise-address**=""\
 	If the node should host a new control plane instance, the IP address the API Server will advertise it's listening on. If not set the default network interface will be used.

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

**--control-plane**=false\
 	Create a new control plane instance on this node

**--discovery-file**=""\
 	For file-based discovery, a file or URL from which to load cluster information.

**--discovery-token**=""\
 	For token-based discovery, the token used to validate cluster information fetched from the API server.

**--discovery-token-ca-cert-hash**=\[\]\
 	For token-based discovery, validate that the root CA public key matches this hash (format: ":").

**--discovery-token-unsafe-skip-ca-verification**=false\
 	For token-based discovery, allow joining without --discovery-token-ca-cert-hash pinning.

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

**--node-name**=""\
 	Specify the node name.

**--tls-bootstrap-token**=""\
 	Specify the token used to temporarily authenticate with the Kubernetes Control Plane while joining the node.

**--token**=""\
 	Use this token for both discovery-token and tls-bootstrap-token when those values are not provided.

## 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
