Before we get into the process of deploying a resource using a deployment manager template, I wanted to quickly explain what the configuration file is and what its relationship is to the template because before using a template to deploy a resource, we must first create a configuration. 

Now, what a configuration file is is a list of resources, and their respective properties that will be part of the deployment. A configuration file contains a top-level resources section, which, in turn, contains a list of resource entries that are used to configure the deployment. Each resource entry includes a name field, a type field, and sometimes, a properties field. 

On the screen, here, you can see what a typical configuration file looks like, when using a template for deployment. The information you see is from a configuration file, called myvm.yaml, that I created ahead of this lesson. If you remember the previous lesson, where I showed you the demovm deployment manager template, you'll recall that I specified all the necessary values for our VM in the demovm.jinja file. 

Since we already configured these values in the template file we'll be using, we don't have to provide this information directly in the configuration file here. Instead, we'll simply pull this information from our template into the configuration, using the imports command, along with a path designation. 

Since both my config file and template both reside in the same templatedemo folder, I don't need to specify a complete path. The name field in the resources section is used to specify a name for the resource being deployed. 

For this exercise, we're calling our new VM myfirstvm. Type specifies the base type of the resource being deployed. Since we already defined the type in our template that we're referencing, we just need to configure the type to reference our template. As you can see here, the config file is pretty bare, when using templates. This makes sense because all the configuration settings are defined in the template file meaning there isn't much needed in the config file. 

So, now that I've explained the config file and template file, let's hop into the next lesson where I'll show you how to deploy a VM using a combination of the config file and template.
