Generate certificate keys
### Synopsis
This command will print out a secure randomly-generated certificate key that can be used with
the "init" command.
You can also use "kubeadm init --upload-certs" without specifying a certificate key and it will
generate and print one for you.
```

Generate keys and certificate signing requests
### Synopsis
Generates keys and certificate signing requests (CSRs) for all the certificates required to run the control plane. This command also generates partial kubeconfig files with private key data in the "users &gt; user &gt; client-key-data" field, and for each kubeconfig file an accompanying ".csr" file is created.
This command is designed for use in [Kubeadm External CA Mode](https://kubernetes.io/docs/tasks/administer-cluster/kubeadm/kubeadm-certs/#external-ca-mode). It generates CSRs which you can then submit to your external certificate authority for signing.
The PEM encoded signed certificates should then be saved alongside the key files, using ".crt" as the file extension, or in the case of kubeconfig files, the PEM encoded signed certificate should be base64 encoded and added to the kubeconfig file in the "users &gt; user &gt; client-certificate-data" field.
```
kubeadm certs generate-csr [flags]
```
### Examples
```
# The following command will generate keys and CSRs for all control-plane certificates and kubeconfig files:
kubeadm certs generate-csr --kubeconfig-dir /tmp/etc-k8s --cert-dir /tmp/etc-k8s/pki

Renew the certificate embedded in the kubeconfig file for the admin to use and for kubeadm itself
### Synopsis
Renew the certificate embedded in the kubeconfig file for the admin to use and for kubeadm itself.
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.
```

Renew the certificate for liveness probes to healthcheck etcd
### Synopsis
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.
