This module has been added to backport the create_resources function to 2.6.4 - 2.6.8.

It has been merged into core in 2.7.0.

The function can be used to convert hashes into resources.

$users3 = {
 'dannyboy454' => {
   'user_name'=>'dlfjdslkf',
   'ensure'=>present,
   'require' => 'User[foobar]',
   'before' => 'User[sally-mae]'
  },
 'bobby-joe' => {'ensure'=>present}
}
create_resources('create_resources::user', $users3)

This works for resource types as well as defined resources and classes.

This was originally written to be used together with an ENC.

Resources can be programitally generated as yaml and passed to a class.

  classes:
    webserver::instances:
      instances:
        instance1:
          foo: bar
        instance2:
          foo: blah

Then puppet code can consume the hash parameters and convert then into resources

  class webserver::instances (
    $instances = {}
  ) {
    create_resources('webserver::instance', $instances)
  }

Now I can dynamically determine how webserver instances are deployed to nodes
