#!/usr/bin/env bash
# ``stack.sh`` is an opinionated OpenStack developer installation. It
# installs and configures various combinations of **Cinder**, **Glance**,
# **Heat**, **Horizon**, **Keystone**, **Nova**, **Neutron**, and **Swift**
# This script's options can be changed by setting appropriate environment
# variables. You can configure things like which git repositories to use,
# services to enable, OS images to use, etc. Default values are located in the
# ``stackrc`` file. If you are crafty you can run the script on multiple nodes
# using shared settings for common resources (eg., mysql or rabbitmq) and build
# a multi-node developer install.
# To keep this script simple we assume you are running on a recent **Ubuntu**
# (14.04 Trusty or newer), **Fedora** (F20 or newer), or **CentOS/RHEL**
# (7 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 ``deb`` and
# ``rpm`` dependencies and other configuration files in this repo.
# Learn more and get the most recent version at http://devstack.org
# Print the commands being run so that we can see the command that triggers
# an error. It is also useful for following along as the install occurs.
