kubeadm_certs_renew_etcd-healthcheck-client [page]deterministic
### Synopsis
Renew the certificate for liveness probes to healthcheck etcd.
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.
``` kubeadm certs renew etcd-healthcheck-client [flags] ```
