#!/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
# Sanity Check
# ============
# Warn users who aren't on oneiric, but allow them to override check and attempt
# installation with ``FORCE=yes ./stack``
DISTRO=$(lsb_release -c -s)
if [[ ! ${DISTRO} =~ (oneiric) ]]; then
echo "WARNING: this script has only been tested on oneiric"

# stack.sh keeps the list of **apt** and **pip** dependencies in external
# files, along with config templates and other useful files. You can find these
# in the ``files`` directory (next to this script). We will reference this
# directory using the ``FILES`` variable in this script.

# 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 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
#
# 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. You can customize
# which services to install as well in your localrc.
