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.

Prerequisites

You have to configure kube_proxy_strict_arp when the kube_proxy_mode is ipvs and kube-vip ARP is enabled.

kube_proxy_strict_arp: true

Install

You have to explicitly enable the kube-vip extension:

kube_vip_enabled: true

You also need to enable kube-vip as HA, Load Balancer, or both:

# 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
