SYNOPSIS

DESCRIPTION

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