**Hi Team,**

We have four node Kubernetes cluster with version 1.23.5 and OS Ubuntu 22.04. By default cluster different certificates are expired after one years and ca certificates are expired after 10 years. We want to renew our certificates for 30 years. Please help us how we can achieve this.

### Cluster information:

Cloud being used: bare-metal  
Installation method: Kubeadm  
Host OS: Ubuntu 22.04  
CNI and version: Calico and 0.3.1
