Implementation Reference
- The handler function for the 'OOS_StartInstances' tool, which orchestrates the bulk start of ECS instances using the OOS template 'ACS-ECS-BulkyStartInstances'.@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)
