def list_attributes(cluster=None, targetType=None, attributeName=None,
    attributeValue=None, nextToken=None, maxResults=None):
    """
    Lists the attributes for Amazon ECS resources within a specified target type and cluster. When you specify a target type and cluster, ListAttributes returns a list of attribute objects, one for each attribute on each resource. You can filter the list of results to a single attribute name to only return results that have that name. You can also filter the results by attribute name and value, for example, to see which container instances in a cluster are running a Linux AMI (ecs.os-type=linux ).

    :example: response = client.list_attributes(
        cluster='string',
        targetType='container-instance',
        attributeName='string',
        attributeValue='string',
        nextToken='string',
        maxResults=123
    )
    
    
    :type cluster: string
    :param cluster: The short name or full Amazon Resource Name (ARN) of the cluster to list attributes. If you do not specify a cluster, the default cluster is assumed.

    :type targetType: string
    :param targetType: [REQUIRED]
            The type of the target with which to list attributes.
            

    :type attributeName: string
    :param attributeName: The name of the attribute with which to filter the results.

    :type attributeValue: string
    :param attributeValue: The value of the attribute with which to filter results. You must also specify an attribute name to use this parameter.

    :type nextToken: string
    :param nextToken: The nextToken value returned from a previous paginated ListAttributes request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value. This value is null when there are no more results to return.
            Note
            This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.
            

    :type maxResults: integer
    :param maxResults: The maximum number of cluster results returned by ListAttributes in paginated output. When this parameter is used, ListAttributes only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another ListAttributes request with the returned nextToken value. This value can be between 1 and 100. If this parameter is not used, then ListAttributes returns up to 100 results and a nextToken value if applicable.
