Overview
Octavia provides network load balancing for OpenStack and is the reference implementation LBaaS (Load Balancer as a Service). Since the OpenStack Liberty release, Octavia has fully replaced and has become the reference implementation for Load Balancing as a Service (LBaaS v2).

This quick start assumes you have a VM set up with SSH and a webserver that you want to expose. The steps included are applicable to other ports and services too. This example assumes you’ve configured your machine following Running an NGinX webserver inside a Docker container. The steps will be similar for bespoke systems too.
