Elastic Compute Service:DeleteInstances

Last Updated:Mar 19, 2024

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

Operation description

  • After an Elastic Compute Service (ECS) instance is released, all the physical resources used by the instance are recycled. Relevant data is erased and cannot be restored.

  • Disks attached to the instance:

    • The disks for which DeleteWithInstance is set to false are retained as pay-as-you-go disks.
    • The disks for which DeleteWithInstance is set to true are released together with the instance.
    • For disks for which DeleteAutoSnapshot is set to false, the automatic snapshots of the disks are retained.
    • For disks for which DeleteAutoSnapshot is set to true, the automatic snapshots of the disks are released.
    • Manual snapshots of the disks are retained.
    • If OperationLocks in the response contains "LockReason" : "security" for an instance, the instance is locked for security reasons. For more information, see API behavior when an instance is locked for security reasons. Even if DeleteWithInstance is set to false for the data disks that are attached to the instance, this parameter is ignored and the data disks are released along with the instance.

Request parameters

ParameterTypeRequiredDescriptionExample
DryRunbooleanNo

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
ForcebooleanNo

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
TerminateSubscriptionbooleanNo

Specifies whether to release an expired subscription instance.

Default value: false.

false
ClientTokenstringNo

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.

RegionIdstringYes

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