嵌套ACS::Template
更新時(shí)間：
調(diào)用其他的模板作為子模板進(jìn)行嵌套執(zhí)行。
用途
嵌套動(dòng)作（ACS::Template）可以調(diào)用其他的模板作為子模板進(jìn)行嵌套執(zhí)行。利用該動(dòng)作，您可以將一個(gè)復(fù)雜的模板進(jìn)行模塊化分解，拆分成多個(gè)子模板進(jìn)行調(diào)用，也可以將常見(jiàn)的運(yùn)維操作定義成一個(gè)可復(fù)用的子模板。另外云產(chǎn)品動(dòng)作是OOS提供的常見(jiàn)類型云產(chǎn)品操作模板，您通過(guò)嵌套云產(chǎn)品動(dòng)作可更便捷地進(jìn)行嵌套調(diào)用。
語(yǔ)法
通過(guò)模板名稱嵌套已創(chuàng)建過(guò)的模板
通用格式（適用于所有可被嵌套模板）
Tasks: - Name: callChildTemplate1 Action: ACS::Template Properties: TemplateName: child_template_name # 必填，子模板名稱 TemplateVersion: v2 # 可選，默認(rèn)取最新的版本。 Parameters: # 可選，子模板，根據(jù)子模板的參數(shù)提供參數(shù)。 ParameterName1: value1{ "Tasks": [ { "Name": "callChildTemplate1", "Action": "ACS::Template", "Properties": { "TemplateName": "child_template_name", "TemplateVersion": "v2", "Parameters": { "ParameterName1": "value1" } } } ] }簡(jiǎn)化格式（僅適用于嵌套云產(chǎn)品動(dòng)作）
Tasks: - Name: taskName # 必填，任務(wù)名稱，如runMyInstances Action: CloudProductActionName1 # 必填，云產(chǎn)品動(dòng)作名稱，如ACS::ECS::RunInstances Properties: ParameterName1: value1 # 可選，根據(jù)云產(chǎn)品動(dòng)作需要的參數(shù)進(jìn)行提供，如ImageId。{ "Tasks": [ { "Name": "taskName", "Action": "CloudProductActionName1", "Properties": { "ParameterName1": "parameterName1" } } ] }
通過(guò)模板內(nèi)容嵌套未創(chuàng)建過(guò)的模板
Tasks:
- Name: callChildTemplate1
Action: ACS::Template
Properties:
TemplateContent:
FormatVersion: OOS-2019-06-01 #必填，模板的版本。
Parameters: #可選，子模板的參數(shù)。
Tasks: #可選，子模板執(zhí)行的動(dòng)作。{

}
]
}限制
嵌套動(dòng)作有如下限制：
模板不能嵌套自身。
不能循環(huán)嵌套，即A嵌套B，B嵌套C，然后C嵌套A。
總的嵌套層數(shù)不能超過(guò)3層。
云產(chǎn)品動(dòng)作屬于一層嵌套，循環(huán)任務(wù)不屬于嵌套。
