#!/usr/bin/env bash # **stack.sh** is an opinionated openstack developer installation. # This script installs and configures *nova*, *glance*, *dashboard* and *keystone* # This script allows you to specify configuration options of what git # repositories to use, enabled services, network configuration and various # passwords. If you are crafty you can run the script on multiple nodes using # shared settings for common resources (mysql, rabbitmq) and build a multi-node # developer install. # To keep this script simple we assume you are running on an **Ubuntu 11.04 # Natty** machine. It should work in a VM or physical server. Additionally we # put the list of *apt* and *pip* dependencies and other configuration files in # this repo.
