Deploys kube-vip as a DaemonSet on all k3s server nodes, advertising a
VIP (192.168.20.2) via ARP. Eliminates the single-point-of-failure
k3s-loadbalancer VM.
- New kube_vip role: RBAC + DaemonSet templates, TLS SAN cert rotation
- playbooks/kube-vip.yaml: migration playbook (serial=1, idempotent)
- Updated k3s install tasks (server primary/secondary, agent) to use k3s_vip
instead of the loadbalancer VM IP
- Added k3s_vip: 192.168.20.2 to group_vars (below DHCP range .11-.250)
Migration steps in playbook header comment.
