## NAME

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

## SYNOPSIS

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

## DESCRIPTION

Generate the kubeconfig for the new control plane components

## OPTIONS

**--certificate-key**=""\
 	Use this key to decrypt the certificate secrets uploaded by init. The certificate key is a hex encoded string that is an AES key of size 32 bytes.

**--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.

**--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.
