azure - ARM模板: issue with output in nested templates

Question

我目前面临嵌套模板的问题。当我应用模板(详细信息如下)时，我从 Azure 得到以下答案:

Azure Error: InvalidTemplate
Message: Deployment template validation failed: 'The template reference 'sandbox.test.portal' is not valid: could not find template resource or resource copy with this name. Please see https://aka.ms/arm-template-expressions/#reference for usage details.'.

但是，我不太明白为什么会出现这个问题，因为对于嵌套模板内的内容，我使用了他们在此处的文档中提供的内容:https://github.com/Azure/azure-quickstart-templates/blob/master/101-azure-dns-new-zone/azuredeploy.json

我的 ARM 模板:

您的模板中有几个小错误:

1. 变量 '-pip' 中的逗号)]",
2. 未定义参数dnsLabelPrefix

嵌套输出中的常见错误。当您使用嵌套模板 azure 时，不会在主模板中找到它。因此，您必须使用带有标识符和 API 的引用函数:"[reference(resourceId('Microsoft.Network/dnszones',parameters('newZoneName')), '2016-04-01').nameServers]".

我修改了您的模板并在我的订阅中进行了验证。
