I have installed a kubernetes cluster with one control pane (1 etcd / master) and 3 worker nodes with the kubeadm procedure: Creating a single control-plane cluster with kubeadm - Kubernetes
root@pi0:~# kubectl get nodes NAME STATUS ROLES AGE VERSION pi0 Ready master 19d v1.15.3 pi1 Ready <none> 12d v1.15.3 pi2 Ready <none> 19d v1.15.3 pi3 Ready <none> 19d v1.15.3 root@pi0:~#
Would you have some procedure to convert my cluster to a HA cluster? I hope to move the kube api to a haproxy load balancer, then create other masters, but I’m overwhelmed by the documentation and dont know where to start without breaking my cluster.
Does somebody could guide me to a correct procedure?
Thanks in advance!
