README

Load Balancer Implementation for Kubernetes in Bare-Metal, Edge, and Virtualization

## OpenELB: Cloud Native Load Balancer Implementation

_Read this in other languages: [English](README.md), [中文](README_zh.md)._

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](https://kubesphere.io), and is currently a vendor neutral and CNCF [Sandbox Project](https://www.cncf.io/sandbox-projects/).

## 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

- [Install OpenELB on Kubernetes](https://openelb.io/docs/getting-started/installation/install-openelb-on-kubernetes/)
- [Install OpenELB on K3s](https://openelb.io/docs/getting-started/installation/install-openelb-on-k3s/)
- [Install OpenELB on KubeSphere](https://openelb.io/docs/getting-started/installation/install-openelb-on-kubesphere/)

## Documentation

You can learn how to use OpenELB in a cloud-based Kubernetes cluster by following the [OpenELB Documentation](https://openelb.io/docs/).

## Adopters

OpenELB has been adopted by [many companies](./ADOPTERS.md) all over the world. If you are using OpenELB in your organization, welcome to join the end user community and add your logo to the [list](./ADOPTERS.md)!

## Roadmap

[OpenELB Roadmap](docs/roadmap.md) lists the features and bug fixes for each milestone. If you have any new ideas, feature requests or suggestions, please submit a proposal.
