Solve the following python programming problem given the following code:
@ require_cluster (1, required_backend = backends.AWS) 
def test_create_silver_volume_with_v2_plugin_api(self, cluster, backend) : 
    "
        Docker >=1.9, using the v2 plugin API, can create a volume with the
        volumes API, and pass a profile argument of silver which is represented
        in the backing volume created on EBS.

        The approach here is to:

        - Create the volume.
        - Create a container using that volume to ensure that it is created.
        - Use the flocker API to find the dataset for the volume.
        - Interface with EBS directly to verify that the created volume has
          'silver' characteristics.
        " 
    self.require_docker ('1.9.0', cluster) 
    node = cluster.nodes [0] 
    docker = get_docker_client (cluster, node.public_address) 
    volume_name = random_name (docker) 
    self._create_volume (docker, volume_name, driver_opts = { 
        'profile' : 'silver', 
}) 
    create_container = self._test_create_container (cluster, volume_name = volume_name) 
    def _get_datasets(unused_arg) : 
        return cluster.client.list_datasets_configuration () 
create_container.addCallback (_get_datasets) 
    def _verify_created_volume_is_silver(datasets) : 
        dataset = next ((d for d in datasets if (d.metadata.get ('name') == volume_name))) 
        volumes = backend.list_volumes () 
        volume = next ((v for v in volumes if (v.dataset_id == dataset.dataset_id))) 
        ebs_volume = backend._get_ebs_volume (volume.blockdevice_id) 
        self.assertEqual (EBSMandatoryProfileAttributes.SILVER.value.volume_type.value, ebs_volume.volume_type) 
create_container.addCallback (_verify_created_volume_is_silver) 
    return create_container 

    
    

    Fix the buggy line: volume_name = random_name (docker)

#Here is Python code to find the dataset for the volume.

volume_name = random_name (self)
