SYNOPSIS

15

DESCRIPTION

17       Renew the certificate for serving etcd.
18
19
20       Renewals run  unconditionally,  regardless  of  certificate  expiration
21       date;  extra  attributes  such  as  SANs  will be based on the existing
22       file/certificates, there is no need to resupply them.
23
24
25       Renewal by default tries to use the certificate authority in the  local
26       PKI  managed  by kubeadm; as alternative it is possible to use K8s cer‐
27       tificate API for certificate renewal, or as a last option, to  generate
28       a CSR request.
29
30
31       After  renewal,  in  order to make changes effective, is is required to
32       restart  control-plane  components  and  eventually  re-distribute  the
33       renewed certificate in case the file is used elsewhere.
