For troubleshooting, two things to first try:

run `git config --global gpg.program gpg2`, to make sure git uses gpg2 and not gpg
run `echo "test" | gpg2 --clearsign`, to make sure gpg2 itself is working
If that all looks all right, one next thing to try:

run `brew install pinentry` to ensure you have a good tool installed for passphrase entry
If after that install and you re-try git commit and still get the "failed to sign the data" error:

run `gpgconf --kill gpg-agent` to kill any running agent that might be hung

This uses terraform's template_file resource to generate a yaml properties file for serverspec to use.

• create the Rakefile in your terraform project root
• create a spec directory and put spec_helper.rb in it
• create the templates/properties.tmpl.yml file
• create the serverspec.tf
• terraform apply

tests

Tests will be matched based on roles defined for a given node.
