#!/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** (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. # Learn more and get the most recent version at http://devstack.org # Make sure custom grep options don't get in the way unset GREP_OPTIONS # Keep track of the devstack directory TOP_DIR=$(cd $(dirname "$0") && pwd) # Import common functions source $TOP_DIR/functions # Determine what system we are running on.
