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
Note: When using
kube-vip
as LoadBalancer for services, additional manual steps are needed.
If using local traffic policy:
kube_vip_enableServicesElection: true
If using ARP mode :
kube_vip_arp_enabled: true
If using BGP mode :
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:
If using control plane load-balancing:
kube_vip_lb_enable: true
