#!/usr/bin/env bash

# **stack.sh** is an opinionated openstack developer installation.

# This script installs and configures *nova*, *glance*, *horizon* 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 11.10

# Oneiric** 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. So start by grabbing this script and the dependencies.

# Learn more and get the most recent version at http://devstack.org

# installation with ``FORCE=yes ./stack``

# Settings

# ========

# This script is customizable through setting environment variables. If you

# want to override a setting you can either::

#

# export MYSQL_PASSWORD=anothersecret

# ./stack.sh

#

# You can also pass options on a single line ``MYSQL_PASSWORD=simple ./stack.sh``

#

# Additionally, you can put any local variables into a ``localrc`` file, like::

#

# MYSQL_PASSWORD=anothersecret

# MYSQL_USER=hellaroot

#

# We try to have sensible defaults, so you should be able to run ``./stack.sh``

# in most cases.

#

# We source our settings from ``stackrc``. This file is distributed with devstack

# and contains locations for what repositories to use. If you want to use other

# repositories and branches, you can add your own settings with another file called

# ``localrc``

#

# If ``localrc`` exists, then ``stackrc`` will load those settings. This is

# useful for changing a branch or repository to test other versions. Also you

# can store your other settings like **MYSQL_PASSWORD** or **ADMIN_PASSWORD** instead

# of letting devstack generate random ones for you.
