I have running kubernetes installed by kubespray.
Due to default "kubelet_rotate_certificates" configuration, kubelet certificates is recreated periodically.
What i want to know is whether it is possible to add SAN(Subject Alternatives Names) to kubelet client-certificate file?
kubelet client certificate is re-created with only CN (node's hostname).
** kubelet client-certificate location : /var/lib/kubelet/pki/kubelet-client-2022-06-14-07-49-59.pem
