RebootInstance - Elastic Compute Service - Alibaba Cloud ドキュメントセンター

Restarts an Elastic Compute Service (ECS) instance.

Operation description

This operation is an asynchronous operation. After you call this operation to restart an ECS instance, the operation sets the status of the ECS instance to Starting and begins the restart process. You can call the DescribeInstanceStatus operation to query the status of the ECS instance. When the status of the ECS instance changes to Running, the instance is restarted.

Notes
- You cannot call this operation to restart an ECS instance that is locked for security reasons. For more information, see API behavior when an instance is locked for security reasons.
- The ECS instance that you want to restart must be in the Running (Running) state.

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.

Request parameters

Parameter	Type	Required	Description	Example
InstanceId	string	Yes	The instance ID.	i-bp67acfmxazb4ph****
ForceStop	boolean	No	Specifies whether to forcefully stop the ECS instance before the instance is restarted. Valid values: true: forcefully stops the ECS instance. If you set this parameter to true, this operation is equivalent to a power-off operation. Cache data that is not written to storage devices on the instance is lost. false: normally stops the ECS instance. Default value: false.	false
DryRun	boolean	No	Specifies whether to perform only a dry run, without performing the actual request. Valid values: true: performs only a dry run. The system checks the request for potential issues, including missing parameter values, incorrect request syntax, service limits, and available ECS resources. If the request fails the dry run, an error message is returned. If the request passes the dry run, the `DryRunOperation` error code is returned. false: performs a dry run and sends the request. If the request passes the dry run, the ECS instance is restarted. Default value: false.	false
