Unlike Apache, however, the module that is suggested for use is not supplied by puppetlabs, but by James Fryman. This module uses some interesting tricks to configure itself. Previous versions of this module used R.I. Pienaar's module_data package. This package is used to configure hieradata within a module. It's used to supply default values to the nginx module.

Giving modules the ability to modify hieradata may prove useful.

How to do it...

In this example, we'll use a Forge module to configure NGINX. We'll download the module and use it to...
