OpenELB is an open-source load balancer implementation for exposing Kubernetes LoadBalancer-type Services in bare-metal, edge, and virtualization environments. It supports BGP and Layer 2 modes, ECMP routing, IP address pool management, and BGP configuration via CRDs, and is a CNCF Sandbox project originally created by KubeSphere.
Use cases
- expose kubernetes loadbalancer services on bare metal
- run load balancer for k3s cluster without cloud provider
- announce kubernetes service IPs via BGP to border routers
- manage external IP address pools for kubernetes services
- replace metallb for loadbalancer services on-premise
- provide external access to services in edge or virtualized clusters
When to choose
- you run Kubernetes or K3s on bare metal, edge, or virtualization where cloud load balancers are unavailable
- you want BGP or Layer 2 announcement of Service IPs with ECMP support
- you want CRD-based BGP configuration and IP pool management
- you use KubeSphere and want seamless LoadBalancer integration
When to avoid
- your cluster runs in a cloud with a native cloud load balancer provider
- you need a general-purpose reverse proxy or ingress controller rather than LoadBalancer Services
- you require a fully mature, graduated CNCF project with long-term commercial support
