test opsworks
# use this file to run chef locally on an opsworks instance
# You'll need to put it in /opt/aws/opsworks/current <-- it should contain a bin/ subdir
# to use it, find reasonable paths for substitution and call your recipe like this:
# bin/chef-solo -o <cookbook>::<recipe> -c test.rb -j /var/lib/aws/opsworks/chef/<date>.json -l info
# The next line is the only thing you really need in this file. The rest is documentation
