def get_id_from_managed_entry
  if should_have_managed_entry?
    entry = managed_entry_store.get(self.class.managed_entry_type, name)
    if entry
      driver = self.driver
      if entry.driver_url != driver.driver_url
        # TODO some people don't send us run_context (like Drivers).  We might need
        # to exit early here if the driver_url doesn't match the provided driver.
        driver = run_context.chef_provisioning.driver_for(entry.driver_url)
      end
      [ driver, entry.reference[self.class.managed_entry_id_name], entry ]
    end
  end
end

#save_managed_entry(aws_object, action_handler, existing_entry: nil) ⇒ Object

Save the ID of this object to Chef.

Parameters:

  • aws_object (AWS::EC2::Core) —

    The AWS object containing the ID.

  • action_handler (Chef::Provisioning::ActionHandler) —

    The action handler, which handles progress reporting, update reporting (“little green text”) and dry run.

  • existing_entry (Chef::Provisioning::ManagedEntry) (defaults to: nil) —

    The existing entry (if any). If this is passed in, and no values are changed, we will not attempt to update it (this prevents us from retrieving it twice).
