+# kube-vip
+
+kube-vip provides Kubernetes clusters with a virtual IP and load balancer for both the control plane (for building a highly-available cluster) and Kubernetes Services of type LoadBalancer without relying on any external hardware or software.
+
+## Install
+
+You have to explicitly enable the kube-vip extension:
+
+```yaml
+kube_vip_enabled: true
+```
+
+You also need to enable
+[kube-vip as HA, Load Balancer, or both](https://kube-vip.io/docs/installation/static/#kube-vip-as-ha-load-balancer-or-both):
+
+```yaml
+# HA for control-plane, requires a VIP
+kube_vip_controlplane_enabled: true
+kube_vip_address: 10.42.42.42
+loadbalancer_apiserver:
+  address: "{{ kube_vip_address }}"
+  port: 6443
+# kube_vip_interface: ens160
+
+# LoadBalancer for services
+kube_vip_services_enabled: false
+# kube_vip_services_interface: ens320
+```
+
+> Note: When using `kube-vip` as LoadBalancer for services,
+[additional manual steps](https://kube-vip.io/docs/usage/cloud-provider/)
+are needed.
+
+If using [ARP mode](https://kube-vip.io/docs/installation/static/#arp) :
+
+```yaml
+kube_vip_arp_enabled: true
+```
+
+If using [BGP mode](https://kube-vip.io/docs/installation/static/#bgp) :
+
+```yaml
+kube_vip_bgp_enabled: true
+kube_vip_local_as: 65000
+kube_vip_bgp_routerid: 192.168.0.2
+kube_vip_bgppeers:
+- 192.168.0.10:65000::false
+- 192.168.0.11:65000::false
+# kube_vip_bgp_peeraddress:
+# kube_vip_bgp_peerpass:
+# kube_vip_bgp_peeras:
+```
