async deploy_resource(resource_attributes: AttributeDict) AttributeDict[source]

Abstract method to define the interface to deploy a new resource at a resource provider. :param resource_attributes: Contains describing attributes of the resource, defined in the Drone implementation! :type resource_attributes: AttributeDict :return: Contains updated describing attributes of the resource. :rtype: AttributeDict

property drone_heartbeat_interval: int

Property that returns the configuration parameter drone_heartbeat_interval. It describes the time between two consecutive updates of the drone status. :return: The heartbeat interval of the drone :rtype: int

property drone_minimum_lifetime: int

Property that returns the configuration parameter drone_minimum_lifetime. It describes the minimum lifetime before a drone is automatically going into draining mode. :return: The minimum lifetime of the drone :rtype: int, None

drone_uuid(uuid) str[source]

Returns the drone uuid consisting of the lower case site name and the first 10 bytes of uuid4 due to constraints on length of a full DNS name (253 bytes). :param uuid: The first 10 bytes of a uuid4 :type uuid: str :return: The drone uuid consisting of the lower case site name and the first 10 bytes of uuid4. :rtype: str
