ALIYUN::ROS::Stack

更新时间:

ALIYUN::ROS::Stack用于创建嵌套资源栈,最多支持5层嵌套。

嵌套资源栈本身可以包含其他嵌套资源栈,构成一个资源栈层次结构。根资源栈是所有嵌套资源栈最终归属的父资源栈,根资源栈的模板称为顶层模板。ALIYUN::ROS::Stack类型在顶层模板中将资源栈作为资源进行嵌套。

您可以将嵌套资源栈模板中的一个资源栈的输出用作另一个资源栈的输入。您也可以使用Fn::GetAtt函数,将函数参数设置为嵌套资源栈的名称和Outputs.NestedStackOutputName格式的输出值,获取嵌套资源栈的输出。更多信息,请参见使用嵌套资源栈

描述

约束

TemplateURL

String

模板主体的文件的位置。

模板主体的文件最大为524,288个字节,URL的最大长度为1024个字节。

URL必须指向位于Web服务器(HTTP、HTTPS)或阿里云OSS存储空间中的模板。例如:oss://ros/template/demooss://ros/template/demo?RegionId=cn-hangzhou

OSS地域如未指定,默认与资源栈RegionId相同。

您必须指定TemplateURLTemplateBodyTemplateId其中一个。如果都指定,则使用TemplateBody

TemplateBody

Map

模板内容,用于简化模板的传递。

内容为原始数据,函数只在子模板中生效,不在当前模板中生效。

您必须指定TemplateURLTemplateBodyTemplateId其中一个。如果都指定,则使用TemplateBody

TemplateId

String

模板ID。

您必须指定TemplateURLTemplateBodyTemplateId其中一个。如果都指定,则使用TemplateBody

TemplateVersion

String

模板版本名。

TimeoutMins

Number

创建或更新资源栈的超时时间。

单位:分。

默认值:60。

Parameters

Map

一组键值对,表示在创建此嵌套资源栈时传递给ROS的参数。

Parameters中的每个键都对应于嵌套资源栈模板中的参数名,每个值对应于参数取值。如果嵌套资源栈需要输入参数,则必须指定此参数。

ResourceGroupId

String

资源组ID。

Tags

List

标签列表。

最多支持20个标签。更多信息。请参见Tags属性

Tags语法

"Tags": [

Key

String

标签键。

长度不超过128个字符,不能以aliyunacs:开头,不能包含http://或者https://

Value

String

标签值。

长度不超过128个字符,不能以aliyunacs:开头,不能包含http://或者https://

返回值

Fn::GetAtt

您可以通过以下代码,获取嵌套资源栈的输出。

{
  "Fn::GetAtt": [
    "<nested_stack>",
    "Outputs.<nested_stack_output_name>"
  ]
}

通过Ref引用嵌套资源栈资源时,将获得嵌套资源栈的ARN。例如:arn:acs:ros::cn-hangzhou:12345****:stacks/test-nested-stack-Demo-jzkyq7mn****/e71c1e04-1a57-46fc-b9a4-cf7ce0d3****
