DESCRIPTION

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