#!/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`` # 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.
