The Puppetfile
Your control repository's branches represent environments, and each environment might have different modules or data. To manage each environment's content, you need a Puppetfile. In the Puppetfile, you specify which modules and data you want in each environment.
A Puppetfile is a formatted text file that specifies the modules and data you want in your control repository (where each branch of the control repo represents an environment). The Puppetfile can specify desired module versions, how to load modules and data, and where to place modules and data in the environment. In your Puppetfile you can declare:
- Modules from the https://forge.puppet.com/.
- Modules from Git repositories.
- Data and other non-module content (such as Hiera data) from Git repositories.
You can declare as much or as little of this content as needed for each environment. In
the Puppetfile, each module or repository is specified by
a mod directive, along with the name of the content and
other information code management needs to correctly install and maintain the declared
modules and data.
