Overview

OpenELB is an open-source load balancer implementation designed for bare-metal Kubernetes clusters.

Why OpenELB

In cloud-based Kubernetes clusters, Services are usually exposed by using load balancers provided by cloud vendors. However, cloud-based load balancers are unavailable in bare-metal environments. OpenELB allows users to create LoadBalancer Services in bare-metal, edge, and virtualization environments for external access, and provides the same user experience as cloud-based load balancers.

Core Features

  • BGP mode and Layer 2 mode
  • ECMP routing and load balancing
  • IP address pool management
  • BGP configuration using CRDs
  • Installation using Helm Chart

Support, Discussion and Contributing

OpenELB is a sub-project of KubeSphere.
