DeleteInstances - Elastic Compute Service - Alibaba Cloud Documentation Center

Releases pay-as-you-go instances or expired subscription instances.

Operation description

Usage notes

After an ECS instance is released, all the physical resources used by the instance are recycled. Relevant data is erased and cannot be restored.
When you release an ECS instance, take note of the following items for the disks attached to the instance:
- The disks for which DeleteWithInstance is set to false are retained as pay-as-you-go disks after the instance is released.
- The disks for which DeleteWithInstance is set to true are released along with the instance.
- If DeleteAutoSnapshot is set to false for a disk attached to the instance, the automatic snapshots of the disk are retained when the instance is released.
- If DeleteAutoSnapshot is set to true for a disk attached to the instance, the automatic snapshots of the disk are released along with the instance.
- Manual snapshots of the disks are retained.
- If OperationLocks in the response contains "LockReason" : "security" when you query the information of the instance, the instance is locked for security reasons. In this case, even if DeleteWithInstance is set to false for the disks that are attached to the instance, the system ignores the DeleteWithInstance value and releases the disks along with the instance. For more information, see API behavior when an instance is locked for security reasons.

Request parameters

Parameter	Type	Required	Description	Example
DryRun	boolean	No	Specifies whether to perform only a dry run without performing the actual request. Default value: false. Valid values: true: performs only a dry run. The system checks whether your AccessKey pair is valid, whether RAM users are granted permissions, and whether the required parameters are specified. If the request fails the dry run, an error message is returned. If the request passes the dry run, the DRYRUN.SUCCESS error code is returned. false: performs a dry run and performs the actual request. If the request passes the dry run, a 2xx HTTP status code is returned and the operation is performed.	false
Force	boolean	No	Specifies whether to forcefully release the instance that is in the Running (`Running`) state. Default value: false. Valid values: true: forcefully releases the instance that is in the Running (`Running`) state. When the Force parameter is set to true, this operation is equivalent to a power-off operation. Temporary data in the memory and storage of the instance is erased and cannot be restored. false: normally releases the instance. This value is valid only for instances that are in the Stopped (`Stopped`) state.	false
TerminateSubscription	boolean	No	Specifies whether to release an expired subscription instance. Default value: false.	false
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. You can use the client to generate the token, but you must make sure that the token is unique among different requests. The token can contain only ASCII characters and cannot exceed 64 characters in length. For more information, see How to ensure idempotence.	123e4567-e89b-12d3-a456-426655440000
RegionId	string	Yes	The region ID of the instance. You can call the DescribeRegions operation to query the most recent region list.	cn-hangzhou
InstanceId	array	Yes	The IDs of instances. You can specify up to 100 instance IDs in a single request.
	string	Yes	The ID of the instance.	i-bp1g6zv0ce8oghu7****
