Deploy HA Kubernetes Cluster with Kube-vip

This guide details creating a High Availability (HA) Kubernetes cluster using kubeadm and kube-vip. It utilizes a stacked etcd topology, where etcd members run on control plane nodes, simplifying management. The core challenge is ensuring kube-vip provides a Virtual IP (VIP) before the cluster is fully bootstrapped.

The solution involves using a Static Pod manifest generated by kube-vip. A critical step for kubeadm v1.29+ is addressing permission issues; the tutorial explains that kubeadm generates a 'super-admin.conf' for initial bootstrap, which kube-vip must use to acquire a leadership lease. After the first node initializes, the manifest is updated to use the standard 'admin.conf'.

This method ensures a resilient control plane accessible via a single VIP endpoint.
