DESCRIPTION

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