# ``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** (F16 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.

# Global Settings
# ===============

# ``stack.sh`` is customizable by setting environment variables.  Override a
# default setting via export::
#
#     export DATABASE_PASSWORD=anothersecret
#     ./stack.sh
#
# or by setting the variable on the command line::
#
#     DATABASE_PASSWORD=simple ./stack.sh
#
# Persistent variables can be placed in a ``localrc`` file::
#
#     DATABASE_PASSWORD=anothersecret
#     DATABASE_USER=hellaroot
#
# We try to have sensible defaults, so you should be able to run ``./stack.sh``
# in most cases.  ``localrc`` is not distributed with DevStack and will never
# be overwritten by a DevStack update.
#
# DevStack distributes ``stackrc`` which contains locations for the OpenStack
# repositories, branches to configure, and other configuration defaults.
# ``stackrc`` sources ``localrc`` to allow you to safely override those settings.
