24 Renewals run unconditionally, regardless of certificate expiration
25 date; extra attributes such as SANs will be based on the existing
26 file/certificates, there is no need to resupply them.

29 Renewal by default tries to use the certificate authority in the local
30 PKI managed by kubeadm; as alternative it is possible to use K8s cer‐
31 tificate API for certificate renewal, or as a last option, to generate
32 a CSR request.

35 After renewal, in order to make changes effective, is required to
36 restart control-plane components and eventually re-distribute the re‐
37 newed certificate in case the file is used elsewhere.
