DESCRIPTION

20       Renew the certificate embedded in the  kubeconfig  file  for  the  con‐
21       troller manager to use.
22
23
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.
27
28
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.
33
34
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.
