Call the DeleteInstance operation to delete an instance.

Usage notes

Only pay-as-you-go instances (including spot instances and Elastic Scheduled Instances) or subscription instances that have expired or been unsubscribed can be deleted.

After a pay-as-you-go instance and the associated resources are deleted, its billing stops. Why is a deleted instance still being billed?

A subscription instance cannot be deleted before it expires or is unsubscribed. You can convert the instance to a pay-as-you-go instance and manually delete it, or manually delete it within the resource retention period after the instance expires or is unsubscribed. If an instance is not renewed after expiration or unsubscription, it will be automatically released.

For details on the retention of resources related to an instance after the instance is deleted, see Status of instance resources after an ECS instance is deleted.

Request parameters

Only the request parameters specific to this operation and some common parameters are listed below. For more information, please refer to Common parameters.

Action string Sample value: DeleteInstance

The operation that you want to perform. Valid value: DeleteInstance.

Version string Sample value: 2020-04-01

The API version. Valid value: 2020-04-01.

ClientToken string Optional Sample value: 333456899ff****

The ClientToken is used to ensure the request idempotency. You can use the client to automatically generate a token, but you must make sure that the token is unique among different requests. This prevents repeated actions due to multiple client retries when the call of the API action times out or an internal server error occurs.

Value: Only ASCII characters are supported. The length is no more than 64 ASCII characters.

DryRun boolean Optional Sample value: false

Specifies whether to precheck this request. Valid values:

true: Sends a check request without deleting the instance. Check items include whether required parameters are filled, request format, and business restrictions. If the check fails, the corresponding error is returned. If the check passes, the error code DryRunOperation is returned.

false (default): Sends a normal request and directly deletes the instance after the check is passed.

InstanceId string Sample value: i-3thhlu8byl4bwbha****

The instance ID.
