#!/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 11.04
# 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. So start by grabbing this script and the dependencies.
# Learn more and get the most recent version at http://devstack.org
# Sanity Check
# ============
# Warn users who aren't on natty, but allow them to override check and attempt
# 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 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.
