#nova_server_user_data(value, args = {}) ⇒ Array<String, Object>

Custom mapping for server user data. Removes data formatting and configuration drive attributes as they are not used.

Options Hash (args):

  • :new_resource (Hash)
  • :new_properties (Hash)
  • :original_resource (Hash)

#rackspace_asg_finalizer(resource_name, new_resource, old_resource) ⇒ Object

Finalizer for the rackspace autoscaling group resource. Extracts metadata and maps into customized personality to provide bootstraping some what similar to heat bootstrap.
