Load Balancer Implementation for Kubernetes in Bare-Metal, Edge, and Virtualization
OpenELB: Cloud Native Load Balancer Implementation
Read this in other languages: English, 中文.
OpenELB is an open-source load balancer implementation designed for exposing the LoadBalancer type of Kubernetes services in bare metal, edge, and virtualization environments.
OpenELB was originally created by KubeSphere, and is currently a vendor neutral and CNCF Sandbox Project.
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 or on-premise 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
- Load balancing in BGP mode and Layer 2 mode
- ECMP routing and load balancing
- IP address pool management
- BGP configuration using CRDs
- Installation using Helm Chart
Quickstart
Documentation
You can learn how to use OpenELB in a cloud-based Kubernetes cluster by following the OpenELB Documentation.
Adopters
