In the previous example, we called a resource called myapp just under the site{} declaration. This manifest, located in the myapp module at manifests/init.pp, declares the application, describes some overridable parameters, and orchestrates applications using the export and consume metaparameters. Notice the following:

• On the first line, the application myapp is used in place of a class or define.
• myapp::db exports to the SQL resource.
• myapp::web consumes the SQL resource.
• myapp::db will run before myapp::web, because myapp::web has a dependency via consume.
• We use the $name variable so that each component receives myapp as a name, taken from myapp {'myapp':}:

application myapp (
  $dbuser = 'wordpress',
  $dbpass = 'w0rdpr3ss!',
  $webpath = '/var/www/wordpress',
  $vhost = 'appserver',
) {
  myapp::db { $name:
    dbuser => $dbuser,
    dbpass => $dbpass,
    export => Sql[$name],
  }
  myapp::web { $name:
    webpath => $webpath,
    consume => Sql[$name],
    vhost => $vhost,
  }
}
