RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

  • Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.

  • API: The API that you can call to perform the action.

  • Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.

  • Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.

    • For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.

    • For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.

  • Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.

  • Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter

Type

Required

Description

Example

ClientToken

string

No

The client token that is used to ensure the idempotence of the request. You can use the client to generate the value, but you must ensure that it is unique among different requests.

The value can be up to 64 characters in length and can contain letters, digits, hyphens (-), and underscores (_).

For more information, see How to ensure idempotence.

123e4567-e89b-12d3-a456-42665544****

RegionId

string

Yes

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

cn-hangzhou

StackGroupName

string

Yes

The name of the stack group. The name must be unique in a region.

The name can be up to 255 characters in length and can contain digits, letters, hyphens (-), and underscores (_). It must start with a digit or letter.

MyStackGroup

OperationPreferences

object

No

The operation settings, in JSON format. The following fields are supported:

  • FailureToleranceCount

The maximum number of stack group operation failures that can occur. In a stack group operation, if the total number of failures does not exceed the FailureToleranceCount value, the operation succeeds. Otherwise, the operation fails.

If FailureToleranceCount is not specified, the default value 0 is used. You can specify one of FailureToleranceCount or FailureTolerancePercentage parameters, but you cannot specify both of them.

Valid values: 0 to 20.

  • FailureTolerancePercentage

The percentage of stack group operation failures that can occur. In a stack group operation, if the percentage of failures does not exceed the FailureTolerancePercentage value, the operation succeeds. Otherwise, the operation fails.

You can specify one of FailureToleranceCount or FailureTolerancePercentage parameters, but you cannot specify both of them.

Valid values: 0 to 100.

  • MaxConcurrentCount

The maximum number of target accounts in which a drift detection operation can be performed at a time.

You can specify one of MaxConcurrentCount or MaxConcurrentPercentage parameters, but you cannot specify both of them.

Valid values: 1 to 20.

  • MaxConcurrentPercentage

The maximum percentage of target accounts in which a drift detection operation can be performed at a time.

You can specify one of MaxConcurrentCount or MaxConcurrentPercentage parameters, but you cannot specify both of them.

Valid values: 1 to 100.
