Right now I am using the base application cookbook to deploy my application with unicorn. However I am looking to use nginx as out web server and unicorn as our application server.

With the current implementation of the application cookbook is it possible to add nginx into the mix? Or am I completely missing something here?

I have modified that opscode application cookbook to include support for node servers and applications. So far things have worked out pretty well and I only have one issue.

When I get to the point where the recipe should clone the repository from git I am prompted to enter the passphrase for the deploy key. The odd thing about this is no passphrase was created for this deploy key.

This is what I am seeing during provisioning:
