Puppet 4.10 Beginner's Guide - Second Edition

Defined resource types

Whereas a class lets you group together related resources, a defined resource type lets you create new kinds of resources, and declare as many instances of them as you like. A defined resource type definition looks a lot like a class (defined_resource_type.pp):

# Manage user and SSH key together
define user_with_key(
  String $key_type,
  String $key,
) {
  user { $title:
    ensure     => present,
    managehome => true,
  }

  file { "/home/${title}/.ssh":
    ensure => directory,
    owner  => $title,
    group  => $title,
    mode   => '0700',
  }

  ssh_authorized_key { $title:
    user => $title,
    type => $key_type,
    key  => $key,
  }
}

You can see that instead of the class keyword, we use the define keyword. This tells Puppet that we are creating a defined resource type instead ...
