NAME

kubeadm certs renew etcd-healthcheck-client - Renew the certificate for liveness probes to healthcheck etcd

SYNOPSIS

kubeadm certs renew etcd-healthcheck-client [OPTIONS]

DESCRIPTION

Renew the certificate for liveness probes to healthcheck etcd.

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.

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.

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.

OPTIONS

--cert-dir="/etc/kubernetes/pki" The path where to save the certificates

--config="" Path to a kubeadm configuration file.

--kubeconfig="/etc/kubernetes/admin.conf" The kubeconfig file to use when talking to the cluster. If the flag is not set, a set of standard locations can be searched for an existing kubeconfig file.

OPTIONS INHERITED FROM PARENT COMMANDS

--azure-container-registry-config="" Path to the file containing Azure container registry configuration information.

--rootfs="" [EXPERIMENTAL] The path to the 'real' host root filesystem.

--version=false --version, --version=raw prints version information and quits; --version=vX.Y.Z... sets the reported version
