Renew the TLS certificates of the cluster

The TLS certificates of a MicroK8s cluster expire after a year. The following steps describe how to renew these certificates:

1. Check the expiration of the certificates:

   sudo microk8s refresh-certs -c
   

   This should produce an output similar to:

   The CA certificate will expire in 3283 days.
   The server certificate will expire in -2 days.
   The front proxy client certificate will expire in -2 days.
   

2. Renew the server certificate:

   sudo microk8s refresh-certs --cert server.crt
   

3. Renew the front-proxy-client certificate:

   sudo microk8s refresh-certs --cert front-proxy-client.crt
