Creating the Puppet manifests

Let's start by creating some folders for our Puppet modules and manifests by executing the following commands:

mkdir provision
cd provision
mkdir modules
mkdir manifests

For each of the modules we want to create, we need to create a folder within the provision/modules folder for the module. Within this folder, we need to create a manifests folder, and within this, our Puppet manifest file, init.pp. Structurally, this looks something like the following:

|-- provision
|   |-- manifests
|   |   `-- vagrant.pp
|   `-- modules
|       |-- our module
|           |-- manifests
|               `-- init.pp
`-- Vagrantfile

Installing Nginx

Let's take a look at what is involved to install Nginx through a module and manifest file provision/modules/nginx/manifests/init.pp. First, we define our class, passing in a variable so that we can change the configuration file we use for Nginx (useful for using the same module for different projects or different environments...
