StopInstances - Elastic Compute Service - Alibaba Cloud Documentation Center

Stops one or more Elastic Compute Service (ECS) instances that are in the Running state. After the operation is called, the state of the instances changes to Stopping and then to Stopped.

Operation description

Usage notes

If the response contains {"OperationLocks": {"LockReason" : "security"}} when you query the information of an instance, the instance is locked for security reasons. No operations are allowed on the instance.
After you enable economical mode for a pay-as-you-go instance that resides in a virtual private cloud (VPC), you can set StoppedMode to KeepCharging. This way, the pay-as-you-go instance continues to be billed after the instance is stopped. The instance type resources and public IP address of the instance are retained.
Batch operations are supported. You can use BatchOptimization to specify the batch operation mode.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

Request parameters

Parameter	Type	Required	Description	Example
DryRun	boolean	No	Specifies whether to perform only a dry run, without performing the actual request. Valid values: true: performs only a dry run. The system checks the request for potential issues, including missing parameter values, incorrect request syntax, and instance status. If the request fails the dry run, an error message is returned. If the request passes the dry run, `DRYRUN.SUCCESS` is returned. Note If you set `BatchOptimization` to `SuccessFirst` and `DryRun` to true, only `DRYRUN.SUCCESS` is returned, regardless of whether the request passes the dry run. false: performs a dry run and performs the actual request. If the request passes the dry run, instances are stopped. Default value: false.	false
RegionId	string	Yes	The region ID of the instance. You can call the DescribeRegions operation to query the most recent region list.	cn-hangzhou
ForceStop	boolean	No	Specifies whether to forcefully stop instances. Valid values: true. This operation is equivalent to the typical power-off operation. Cache data that is not written to storage devices on instances is lost. false. Default value: false.	false
StoppedMode	string	No	The stop mode of the pay-as-you-go instance. Valid values: StopCharging: economical mode. For information about how `StopCharging` takes effect, see the "Prerequisites" section in Economical mode. KeepCharging: standard mode. After the instance is stopped in standard mode, you continue to be charged for it. Default value: If the prerequisites required for enabling economical mode are met and you have enabled the mode in the ECS console, the default value is StopCharging . For more information, see the "Enable economical mode" section in `Economical mode`. Otherwise, the default value is `KeepCharging`.	KeepCharging
BatchOptimization	string	No	The batch operation mode. Valid values: AllTogether: In this mode, if all instances are stopped, a success message is returned. If an instance fails the verification, all instances fail to stop and an error message is returned. SuccessFirst: In this mode, each instance is separately stopped. The response contains the operation results for each instance. Default value: AllTogether.	AllTogether
InstanceId	array	Yes	The IDs of instances.
	string	Yes	The ID of instance N. Valid values of N: 1 to 100.	i-bp67acfmxazb4p****

InstanceId	string	The ID of the instance.	i-bp67acfmxazb4p****
CurrentStatus	string	The current status of the instance.	Stopping
PreviousStatus	string	The status of the instance before the operation was called.	Running

403	InstanceNotReady	The specified instance is not ready for use.	The resource is in a state that does not support the current operation. Try again later and check whether the instance state supports the operation.
404	InvalidInstanceId.NotFound	%s	The specified instance does not exist. Check whether the InstanceId parameter is valid.
404	InvalidInstanceIds.NotFound	The specified InstanceIds does not exist.	The specified InstanceId parameter does not exist. You can call the DescribeInstances operation to query the state of the instance.
404	InvalidInstanceId.NotFound	The specified InstanceId does not exist.	The specified instance does not exist.
409	InvalidOperation.Conflict	Request was denied due to conflict with a previous request, please try again later.	-
