Features
kube-vip was originally created to provide a HA solution for the Kubernetes control plane, but over time it has evolved to incorporate that same functionality for Kubernetes Services of type LoadBalancer. Some of the features include:
- VIP addresses can be IPv4, IPv6, or DNS name
- Control plane load balancing:
- Floating IP in ARP (Layer 2) or BGP (Layer 3) modes
- Uses leader election
- Support for
kubeadm
-provisioned clusters (via static Pods) - Support for K3s and others (via DaemonSets)
- IPVS mode for true load balancing (kube-vip ≥ 0.4)
- Dynamic DNS support
- Service of type
LoadBalancer
:- Uses leader election for ARP (Layer 2)
- Multiple nodes with BGP
- Address pools scoped per Namespace or cluster
- Addresses from CIDR blocks or IP ranges
- DHCP support
- Exposure to gateways via UPnP
- Automated manifest generation, vendor API integrations, and much more...
