#!/usr/bin/env bash

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

# This script installs and configures various combinations of *Glance*,

# *Horizon*, *Keystone*, *Melange*, *Nova*, *Quantum* and *Swift*

# 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

# Sanity Check

# ============

# Warn users who aren't on oneiric, but allow them to override check and attempt

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

# Settings

# ========

# ``stack.sh`` is customizable through setting environment variables. If you

# want to override a setting you can set and export it::

#

# 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::

#

# MYSQL_PASSWORD=anothersecret

# MYSQL_USER=hellaroot

#

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

# in most cases.

#

# DevStack distributes ``stackrc`` which contains locations for the OpenStack

# repositories and branches to configure. ``stackrc`` sources ``localrc`` to

# allow you to override those settings and not have your changes overwritten

# when updating DevStack.

# We support HTTP and HTTPS proxy servers via the usual environment variables

# **http_proxy** and **https_proxy**. They can be set in ``localrc`` if necessary or

# on the command line::

#

# http_proxy=http://proxy.example.com:3128/ ./stack.sh

source ./stackrc

# Destination path for installation ``DEST``

DEST=${DEST:-/opt/stack}
