Elastic Compute Service:StopInstances

更新時間:Dec 24, 2024

Stops Elastic Compute Service (ECS) instances. You can specify parameters to determine whether to forcefully stop the instances, the stop mode, and the batch operation mode.

Operation description

This operation is an asynchronous operation. After you call this operation to stop ECS instances, the operation sets the status of the ECS instances to Stopping and begins the stop process. You can call the DescribeInstanceStatus operation to query the status of the ECS instances. When the status of the ECS instances changes to Stopped, the instances are stopped.

Precautions

  • You cannot call this operation to stop ECS instances that are locked for security reasons. For more information, see API behavior when an instance is locked for security reasons.
  • After you enable the default economical mode for all pay-as-you-go ECS instances located in virtual private clouds (VPCs) in your account, you can set StoppedMode to KeepCharging for the pay-as-you-go ECS instances that you want to stop to enable standard mode. This way, the instances continue to be billed after they are stopped. The instance type resources and public IP addresses of the instances are retained.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

  • Operation: the value that you can use in the Action element to specify the operation on a resource.
  • Access level: the access level of each operation. The levels are read, write, and list.
  • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
    • The required resource types are displayed in bold characters.
    • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
  • Condition Key: the condition key that is defined by the cloud service.
  • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Request parameters

ParameterTypeRequiredDescriptionExample
DryRunbooleanNo

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
RegionIdstringYes

The region ID of the instance. You can call the DescribeRegions operation to query the most recent region list.

cn-hangzhou
ForceStopbooleanNo

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
StoppedModestringNo

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
BatchOptimizationstringNo

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
InstanceIdarrayYes

The IDs of ECS instances. You can specify 1 to 100 instance IDs.

stringYes

The ID of the ECS instance.
