CreateStack

The operation that you want to perform. Set the value to CreateStack.

The key of the parameter. If the key and value of the parameter are not specified, the key and value in the template are used by default.

Maximum value of N: 200.

The value of the parameter.

Maximum value of N: 200.

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

The name of the stack.

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.

Specifies whether to disable rollback on stack creation failure. Default value: false.

Valid values:

• true: disables rollback on stack creation failure.
• false: enables rollback on stack creation failure.

The structure that contains the template body. The template body must be 1 to 524,288 bytes in length. If the length of the template body is longer than required, we recommend that you add parameters to the HTTP POST request body to avoid request failures due to excessive length of URLs.

The URL for the file that contains the stack policy. The URL must point to a policy located in an HTTP or HTTPS web server or an Alibaba Cloud OSS bucket. Examples: oss://ros/stack-policy/demo and oss://ros/stack-policy/demo?RegionId=cn-hangzhou. The policy can be up to 16,384 bytes in length and the URL can be up to 1,350 bytes in length. If the region of the OSS bucket is not specified, the RegionId parameter value is used by default.

The timeout period that is specified for the stack creation request.

• Default value: 60.
• Unit: minutes.

The structure that contains the stack policy body. The stack policy body must be 1 to 16,384 bytes in length.

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.

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

For more information, see How to ensure idempotence.

The URL for the file that contains the template body. The URL must point to a template located in an HTTP or HTTPS web server or an Alibaba Cloud OSS bucket. Examples: oss://ros/template/demo and oss://ros/template/demo?RegionId=cn-hangzhou. The template can be up to 524,288 bytes in length. If the region of the OSS bucket is not specified, the RegionId parameter value is used by default.

The callback URL for receiving stack event N. Only HTTP POST is supported.

• Maximum value of N: 5.
• Each URL can be up to 1,024 bytes in length.

ROS sends a notification to the specified URL when the stack status changes. If rollback is enabled on the stack, notifications are sent if the stack is in the CREATE_ROLLBACK or ROLLBACK state, but are not sent when the stack is in the CREATE_FAILED or UPDATE_FAILED state.

Notifications are sent regardless of whether the Outputs parameter is specified. The following code is an example of a notification:

{
    "Outputs": [
        {
            "Description": "No description given",
            "OutputKey": "InstanceId",
            "OutputValue": "i-xxx"
        }
    ],
    "StackId": "80bd6b6c-e888-4573-ae3b-93d29113****",
    "StackName": "test-notification-url",
    "Status": "CREATE_COMPLETE"
}
                                

The name of the RAM role. ROS assumes the specified RAM role to create the stack and call API operations by using the credentials of the role.

All operations will be performed under this role. If a RAM user is authorized to perform operations on the stack but does not have the permission to use the role, ROS still uses the role and grants the role the least privilege.

If you do not specify this parameter, ROS uses the role previously associated with the stack. If no roles are available, ROS uses the temporary credentials generated from the credentials of your account.

The RAM role name can be up to 64 characters in length.

Specifies whether to enable deletion protection on the stack. Default value: Disabled. Valid values:

• Enabled: enables deletion protection on the stack.
• Disabled: disables deletion protection on the stack. You can release the stack by using the ROS console or the DeleteStack operation.
