#!/usr/bin/env bash # **stack.sh** is rackspace cloudbuilder's opinionated openstack dev installation. # Settings/Options # ================ # This script is customizable through setting environment variables. If you # want to override a setting you can either:: # # export MYSQL_PASS=anothersecret # ./stack.sh # # or run on a single line ``MYSQL_PASS=simple ./stack.sh`` # or simply ``./stack.sh`` # This script exits on an error so that errors don't compound and you see # only the first error that occured. set -o errexit # Print the commands being run so that we can see the command that triggers # an error. It is also useful for following allowing as the install occurs. set -o xtrace # Warn users who aren't on natty if ! grep -q natty /etc/lsb-release; then echo "WARNING: this script has only been tested on natty" fi # Important paths: ``DIR`` is where we are executing from and ``DEST`` is # where we are installing openstack.
