# kubeadm-certs-renew-apiserver-kubelet-client(1)

Renew the certificate for the API server to connect to kubelet

Eric Paris Jan 2015

## NAME

kubeadm certs renew apiserver-kubelet-client - Renew the certificate for the API server to connect to kubelet

## SYNOPSIS

**kubeadm certs renew apiserver-kubelet-client** \[OPTIONS\]

## DESCRIPTION

Renew the certificate for the API server to connect to kubelet.

Renewals run unconditionally, regardless of certificate expiration date; extra attributes such as SANs will be based on the existing file/certificates, there is no need to resupply them.

Renewal by default tries to use the certificate authority in the local PKI managed by kubeadm; as alternative it is possible to use K8s certificate API for certificate renewal, or as a last option, to generate a CSR request.

After renewal, in order to make changes effective, is required to restart control-plane components and eventually re-distribute the renewed certificate in case the file is used elsewhere.

## OPTIONS

**--cert-dir**="/etc/kubernetes/pki"\
 	The path where to save the certificates

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

**--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.

## 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
