    Elastic Compute Service:StartInstance

    Last Updated:Nov 14, 2024

    Starts an Elastic Compute Service (ECS) instance. You can specify the ID of an ECS instance and parameters, such as InitLocalDisk, in the request based on your business requirements to start the instance.

    Operation description

    This operation is an asynchronous operation. After you call this operation to start an ECS instance, the operation sets the status of the ECS instance to Starting and begins the startup 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 started.

    Precautions

    • You cannot call this operation to start 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 start must be in the Stopped (Stopped) state.
    • If an ECS instance is stopped in economical mode, the instance may fail to be started due to insufficient resources.

    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.

    Request parameters

    ParameterTypeRequiredDescriptionExample
    InstanceIdstringYes

    The ID of the instance that you want to start.

    		i-bp67acfmxazb4p****
    InitLocalDiskbooleanNo

    Specifies whether to restore the ECS instance to the initial health state on startup if a local disk fails. This parameter is applicable to ECS instances that are equipped with local disks, such as d1, i1, and i2 instances. Valid values:

    • true: restores the ECS instance to the initial health state on startup.

      **

      Warning: After the ECS instance is restored to the initial health state, data stored on the local disks of the instance is lost.

    • false: does not restore the ECS instance to the initial health state on startup. The instance remains in the current state.

    Default value: false.

    		true
    DryRunbooleanNo

    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 AccessKey pair, the permissions of the RAM user, and the required parameters. 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 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.

    		true
