        Pulls an image. Similar to the ``docker pull`` command.

        Args:
            repository (str): The repository to pull
            tag (str): The tag to pull
            stream (bool): Stream the output as a generator. Make sure to
                consume the generator, otherwise pull might get cancelled.
            auth_config (dict): Override the credentials that are found in the
                config for this request.  ``auth_config`` should contain the
                ``username`` and ``password`` keys to be valid.
            decode (bool): Decode the JSON data from the server into dicts.
                Only applies with ``stream=True``
