Varnish load balancer with two Apache/PHP backends for an AWX demo.

Ansible AWX Tower Demo - Varnish load-balanced PHP App

This repository contains a demonstration PHP app that runs with three servers: a Varnish proxy frontend, and two PHP app server backends.

It uses a number of Ansible Galaxy collections and roles, and is meant to demonstrate how to run a playbook and use a dynamic AWS inventory in Ansible AWX or Tower.

The repository was created to demonstrate AWX and Tower for Jeff Geerling's Ansible 101 video series and Ansible for DevOps.
