DeleteInstances - Elastic Compute Service - Alibaba Cloud Documentation Center

Releases multiple pay-as-you-go Elastic Compute Service (ECS) instances or expired subscription ECS instances at a time. You can configure parameters to specify whether to release the disks attached to the instances or retain the disks as pay-as-you-go disks.

Operation description

Warning After an ECS instance is released, all physical resources used by the instance are reclaimed. Relevant data is erased and cannot be restored.

After an ECS instance is released, the manual snapshots of the disks attached to the instance are retained. Whether the disks and the automatic snapshots of the disks are released is determined by the options that you configured when you created the instance and disks. Before you release an ECS instance, you can call the DescribeDisks operation to query the parameters of the disks attached to the instance and the automatic snapshots.

If DeleteWithInstance is set to false, the disks are changed to pay-as-you-go disks and retained. If DeleteWithInstance is set to true, the disks are released along with the instance.
If DeleteAutoSnapshot is set to false, the automatic snapshots are retained. If DeleteAutoSnapshot is set to true, the automatic snapshots are released along with the instance.

Note If an ECS instance is locked for security reasons, the disks attached to the instance are released along with the instance even if DeleteWithInstance is set to false for the disks.

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.

Operation	Access level	Resource type	Condition key	Associated operation
ecs:DeleteInstances	delete	*Instance `acs:ecs:{#regionId}:{#accountId}:instance/{#instanceId}`	none	none

Request parameters

Parameter	Type	Required	Description	Example
DryRun	boolean	No	Specifies whether to perform only a dry run, without performing the actual request. true: performs only a dry run. The system checks the request for potential issues, including invalid AccessKey pairs, unauthorized Resource Access Management (RAM) users, and missing parameter values. 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. Default value: false.	false
Force	boolean	No	Specifies whether to forcefully release the ECS instance in the Running (`Running`) state. Valid values: true: forcefully releases the ECS instance in the Running (`Running`) state. false: normally releases the ECS instance. This value is valid only if the instance is in the Stopped (`Stopped`) state. Default value: false. Warning** 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
TerminateSubscription	boolean	No	Specifies whether to release the expired subscription instance. Valid values: true false 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 ECS instances. You can specify 1 to 100 ECS instances.
	string	Yes	The ID of the ECS instance.	i-bp1g6zv0ce8oghu7****

Error codes

HTTP status code	Error code	Error message	Description
400	InvalidParameter.CrossRegionNotSupport	Instances of multiple regions not support.	-
400	DRYRUN.SUCCESS	This request is a dryrun request with successful result.	The request is checked and determined as valid.
400	DependencyViolation.SLBConfiguring	Specified operation is denied as your instance is using by another product.	The instance is referenced by an SLB instance that is being configured.
400	DependencyViolation.RouteEntry	Specified instance is used by route entry.	Custom route entries exist in the VPC and the VPC cannot be deleted.
403	InvalidParameter.TooManyInstanceIds	Instance ids cannot be more than 100.	-
403	InvalidInstanceIds.ValueNotSupported	The specified instanceIds is not valid.	-
403	InvalidOperation.DeletionProtection	The operation is not allowed due to deletion protection.	Instance has release protection turned on, so this operation cannot be performed
403	InvalidOperation.DeletionProtection	%s	The operation is invalid. Disable release protection for the instance first.
403	ChargeTypeViolation	%s	-
403	IncorrectInstanceStatus.Initializing	%s	-
403	InvalidOperation.EniLinked	%s	The operation is invalid because the current ENI of the instance is associated with other ENIs. You must disassociate the ENI from the other ENIs before you can unbind the ENI from the instance.
403	IncorrectInstanceStatus	%s	The instance is in a state that does not support the current operation.
403	InstanceLockedForSecurity	The specified operation is denied as your instance is locked for security reasons.	-
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	%s	The specified instance does not exist. Check whether the InstanceId parameter is valid.
500	InvalidParameter	Invalid parameters.	-
500	InternalError	The request processing has failed due to some unknown error.	An internal error has occurred. Try again later.
