Introducing the Puppet module

The Puppet module is a collection of code and data that usually solves a particular problem, such as the installation and configuration of a web server. A module is packaged and distributed in the TAR (tape archive) format. When a module is installed, Puppet extracts the archive file on the disk, and the output of the installation process is a module directory that contains Puppet manifests (code), static files (data), and template files (code and data).

Static files are typically some kind of configuration files that we want to distribute across all the nodes in the cluster. For example, if we want to ensure that all the nodes in the cluster are using the same DNS server configuration, we can include the /etc/resolv.conf file in the module and tell Puppet to apply it across all the nodes. This is just an example of how static files are used in Puppet and not a recommendation for how to configure DNS servers.

Like static files, template files can also be used...
