stack.sh

#!/usr/bin/env bash

# ``stack.sh`` is an opinionated OpenStack developer installation.  It
# installs and configures various combinations of **Ceilometer**, **Cinder**,
# **Glance**, **Heat**, **Horizon**, **Keystone**, **Nova**, **Neutron**,
# 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 a recent **Ubuntu**
# (12.04 Precise or newer) or **Fedora** (F18 or newer) machine.  (It may work
# on other platforms but support for those platforms is left to those who added
# them to DevStack.)  It should work in a VM or physical server.  Additionally
# we maintain a list of ``apt`` and ``rpm`` dependencies and other configuration
# files in this repo.

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