.SH NAME
.PP
kubeadm certs renew scheduler.conf - Renew the certificate embedded in the kubeconfig file for the scheduler manager to use


.SH SYNOPSIS
.PP
\fBkubeadm certs renew scheduler.conf\fP [OPTIONS]


.SH DESCRIPTION
.PP
Renew the certificate embedded in the kubeconfig file for the scheduler manager to use.

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

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

.PP
After renewal, in order to make changes effective, is required to restart control-plane components and eventually re-distribute the renewed certificate in case the file is used elsewhere.
