OpenELB
OpenELB exposes Kubernetes LoadBalancer services externally in bare-metal, edge, and virtualization environments. It assigns service addresses from Eip-managed IP pools and supports BGP, Layer 2, and VIP load-balancing modes. BGP mode uses GoBGP to publish routes to peer routers and supports ECMP, while BgpConf and BgpPeer custom resources configure BGP properties. Layer 2 mode requires infrastructure that permits anonymous ARP/NDP packets. VIP mode uses VRRP for high availability. OpenELB can be installed with kubectl manifests or Helm 3 in Kubernetes 1.15 or later, and guides are listed for Kubernetes, K3s, and KubeSphere. The project currently supports IPv4 only and is not a managed service. Layer 2 and VIP modes forward through one active node, so failover can briefly interrupt services and bandwidth is limited by that node. BGP requires a router supporting BGP and ECMP. OpenELB uses Apache License 2.0.
