#!/usr/bin/env bash # **stack.sh** is an opinionated openstack dev installation. # To keep this script simple we assume you are running on an **Ubuntu 11.04 # Natty** machine. It should work in a VM or physical server. Additionally we # put the list of *apt* and *pip* dependencies and other configuration files in # this repo. So start by grabbing this script and the dependencies. # You can grab the most recent version of this script and files from Rackspace # Cloud Builders at https://github.com/cloudbuilders/devstack # Sanity Check # ============ # Warn users who aren't on natty, but allow them to override check and attempt # installation with ``FORCE=yes ./stack`` if ! grep -q natty /etc/lsb-release; then echo "WARNING: this script has only been tested on natty" if [[ "$FORCE" != "yes" ]]; then echo "If you wish to run this script anyway run with FORCE=yes" exit 1 fi fi #The following makes fresh mininmal installs (i.e. LXCs) happy apt-get update apt-get install -y sudo # stack.sh keeps the list of **apt** and **pip** dependencies in external # files, along with config templates and other useful files. You can find these # in the ``files`` directory (next to this script). We will reference this # directory using the ``FILES`` variable in this script. FILES=`pwd`/files if [ ! -d $FILES ]; then echo "ERROR: missing devstack/files - did you grab more than just stack.sh?" exit 1 fi # Settings # ======== # This script is customizable through setting environment variables. If you # want to override a setting you can either:: # # export MYSQL_PASS=anothersecret # ./stack.sh # # You can also pass options on a single line ``MYSQL_PASS=simple ./stack.sh`` # # We try to have sensible defaults, so you should be able to run ``./stack.sh`` # in most cases. # So that errors don't compound we exit on any errors so 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.
