CreateSDG - ENS - Alibaba Cloud Documentation Center

Creates a shared data group (SDG) on an Android in Container (AIC) instance.

Operation description

A SDG can be regarded as a data partition image of a virtual device. You can save a data partition of a virtual device as an SDG. A created SDG can be deployed in data partitions of other virtual devices to achieve rapid data distribution and application. The procedure for calling SDG-related API operations:

Call the CreateSDG operation to create an SDG, which is bound to AIC Instance A (InstanceId). After you create the SDG, a blank cloud disk (also known as an original cloud disk) is attached to Device A (InstanceId).
Install applications on and deliver files to AIC Instance A (InstanceId).
Call the SaveSDG operation to save the data disk of AIC instance A as SDG A.
Call the DeploySDG operation to deploy SDG A to AIC Instance B. This operattion is executed asynchronously. You can call the DescribeARMServerInstances operation to query the status of AIC Instance B. If the status of AIC Instance B changes to success, AIC insance B is available, and AIC Instances A and B have the same applications running.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

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

Parameter	Type	Required	Description	Example
InstanceId	string	Yes	The ID of the AIC instance. You can call the DescribeARMServerInstances operation to query the ID.	aic-xxxx
Size	string	No	The maximum capacity of the SDG. Unit: GB. Note To save costs, we recommend that you specify this parameter based on your business requirements. The first time that you create an SDG, the Size parameter is required. When the amount of data increases, you can pass a new Size parameter for resizing. If the value of the new Size parameter is greater than the value of the old Size parameter, the disk size of the SDG is increased to the size that is specified by the new Size parameter. If the value of the new Size parameter is empty or smaller than that of the old Size parameter, no operation is performed.	20
Description	string	No	The description of the SDG. Note We recommend that you specify this parameter in details for subsequent queries.
FromSDGId	string	No	The ID of the SDG from which you want to create an SDG. Note The first time you create an SDG, the FromSDGId parameter is empty. If the value of the FromSDGId parameter is invalid or does not correspond to an original disk, an error is reported. If the value of the FromSDGId parameter is not empty, you have created an SDG, and the operation is performed on the existing SDG.	sdg-xxxxx
