Use DeleteInstances to release multiple ECS instances - Elastic Compute Service - Alibaba Cloud - Elastic Compute Service

Deletes or releases multiple pay-as-you-go instances or expired subscription instances in a batch. You can use parameters to specify whether to release or convert cloud disks to pay-as-you-go disks and retain them.

Operation description

Warning After an instance is released, all physical resources used by the instance are reclaimed. All related data is permanently lost and cannot be recovered.

Manual snapshots of cloud disks are retained and continue to incur charges. You can call DeleteSnapshot to delete them.
Whether cloud disks and automatic snapshots attached to the instance are released depends on the parameter settings specified when they were created. Before you release an instance, you can call DescribeDisks and ModifyDiskAttribute to query and modify the related parameter settings:
- If DeleteWithInstance=false, the cloud disk is converted to a pay-as-you-go cloud disk and retained. Otherwise, the cloud disk is released along with the instance.
- If DeleteAutoSnapshot=false, the automatic snapshots are retained. Otherwise, the automatic snapshots are released along with the instance.
Elastic IP addresses (EIPs) are not released along with the instance. You can call ReleaseEipAddress to release them.
Important For security-locked instances, even if the DeleteWithInstance parameter of a cloud disk is set to false, this attribute is ignored and the cloud disk is released along with the instance.

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter	Type	Required	Description	Example
DryRun	boolean	No	Specifies whether to perform only a dry run, without performing the actual request. true: sends a check request without querying resource status. The check items include whether your AccessKey pair is valid, whether Resource Access Management (RAM) user authorization is granted, and whether the required parameters are specified. If the check fails, the corresponding error is returned. If the check succeeds, the DRYRUN.SUCCESS error code is returned. false: sends a Normal request. After the check succeeds, a 2xx HTTP status code is returned and the resource status is queried directly. Default value: false.	false
Force	boolean	No	Specifies whether to forcefully release an instance that is in the Running (`Running`) state. true: forcefully releases ECS instance that is in the Running (`Running`) state. false: releases ECS instance only when it is in the Stopped (`Stopped`) state. Default value: false. Warning Forceful release is equivalent to powering off ECS instance. All in-memory data and temporary data in the storage are erased and cannot be recovered. .	false
ForceStop	boolean	No	Specifies whether to forcefully shut down the instance before release when the instance is in the Running (`Running`) state. This parameter takes effect only when `Force=true`. Valid values: true: forcefully shuts down and releases the instance. This is equivalent to a power-off operation. The instance directly enters the resource release process. Warning Forceful release is equivalent to powering off the instance. All in-memory data and temporary data in the storage are erased and cannot be recovered. false: performs a standard shutdown before releasing the instance. This mode causes the release process to take several minutes. You can configure service draining actions during the operating system shutdown to reduce noise in your business systems. Default value: true.	true
TerminateSubscription	boolean	No	Specifies whether to release an expired subscription instance. true: releases the instance. false: does not release the 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 make sure that the token is unique among different requests. The ClientToken value 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 instances. You can call DescribeRegions to query the most recent region list.	cn-hangzhou
InstanceId	array	Yes	The instance ID array. Array length: 1 to 100.	i-bp1g6zv0ce8oghu7****
	string	No	The instance ID.	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.
400	DependencyViolation.RouteEntry	Specified instance is used by route entry.	Custom route entries exist in the VPC and the VPC cannot be deleted.
500	InvalidParameter	Invalid parameters.
500	InternalError	The request processing has failed due to some unknown error.
403	InvalidParameter.TooManyInstanceIds	Instance ids cannot be more than 100.	InstanceIds 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	ChargeTypeViolation	%s	The payment type conflicts. This operation is not supported for resources of the payment type.
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.
403	OperationDenied.SystemInstanceNotSupport	The system instance does not support the %s operation because %s.
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
