Guardfile.mirror

#!/usr/bin/ruby
#
# Guardfile which uses guard-rsync to perform a real-time mirror of
# the entire Crowbar tree (including barclamps) to another location,
# e.g. inside a VM, where you can then run barclamp_install.rb etc.
# to install the files to their final location in the merged tree
# under /opt/dell.
#
# This is a different approach to Guardfile.tree-merge, which rsyncs
# the files directly to the merged tree, skipping any installation
# actions such as uploading cookbooks via knife, etc.
#
# Usage
# -----
#
# First ensure you have the necessary gems by cd'ing to this directory
# and running 'bundle'.  Doing this inside an rvm gemset is recommended.
#
# Then use as follows:
#
#   # Set the rsync target; this can also be a local path
#   $ export GUARD_RSYNC_TARGET=root@192.168.124.10:/root/crowbar
#
#   # Launch the guard watcher:
#   $ bundle exec guard -G Guardfile.mirror
#
