Implementation Reference
- The main handler function for the tool OOS_StartInstances, which starts multiple ECS instances using the OOS template 'ACS-ECS-BulkyStartInstances'. Note: The tool is named 'OOS_StartInstances', not exactly 'StartInstances', but matches the search.@tools.append def OOS_StartInstances( InstanceIds: List[str] = Field(description='AlibabaCloud ECS instance ID List'), RegionId: str = Field(description='AlibabaCloud region ID', default='cn-hangzhou'), ): """批量启动ECS实例，适用于需要同时管理和启动多台ECS实例的场景，例如应用部署和高可用性场景。""" parameters = { 'regionId': RegionId, 'resourceType': 'ALIYUN::ECS::Instance', 'targets': { 'ResourceIds': InstanceIds, 'RegionId': RegionId, 'Type': 'ResourceIds' } } return _start_execution_sync(region_id=RegionId, template_name='ACS-ECS-BulkyStartInstances', parameters=parameters)
- Helper function used by OOS_StartInstances to synchronously start an OOS execution and poll until completion.def _start_execution_sync(region_id: str, template_name: str, parameters: dict): client = create_client(region_id=region_id) start_execution_request = oos_20190601_models.StartExecutionRequest( region_id=region_id, template_name=template_name, parameters=json.dumps(parameters) ) start_execution_resp = client.start_execution(start_execution_request) execution_id = start_execution_resp.body.execution.execution_id while True: list_executions_request = oos_20190601_models.ListExecutionsRequest( region_id=region_id, execution_id=execution_id ) list_executions_resp = client.list_executions(list_executions_request) status = list_executions_resp.body.executions[0].status if status == FAILED: status_message = list_executions_resp.body.executions[0].status_message raise exception.OOSExecutionFailed(reason=status_message) elif status in END_STATUSES: return list_executions_resp.body time.sleep(1)
