- Use this part of kubernetes documentation
- You should copy only next certs to you new control plane node

Hi!
I have an existing cluster with 3 master and 5 worker nodes (Kubernetes v 1.14.x). I'm installed cluster from this guide - https://github.com/cookeem/kubeadm-ha/blob/master/README.md.
How can I add new control plane (master) node to existing configured claster?
On this new 2 control plane nodes I have a configured keepalived - it works with existing other 3 keepalived instances. And I have installed: kubeadm, kubectl, kubelet, docker and docker-compose on 2 control plane.
Please help
