NAME
       kubeadm certs renew etcd-peer - Renew the certificate for etcd nodes to
       communicate with each other



SYNOPSIS
       kubeadm certs renew etcd-peer [OPTIONS]



DESCRIPTION
       Renew the certificate for etcd nodes to communicate with each other.


       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=""    [EXPERIMENTAL] The path to the 'real' host root
       filesystem.


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