What is a homelab HA Kubernetes cluster?

It's three+ nodes running kubeadm with etcd quorum, load balancers, GitOps — all on your hardware, no cloud.

How do I build HA Kubernetes on Proxmox?

Terraform VMs, Ansible bootstrap, FluxCD sync. Start with single DC, add nodes.

Is FluxCD necessary for homelab K8s?

Not 'necessary,' but it beats manual kubectl apply forever. Pull-based, secure.
