嵌套模板，使用AzureRM在同一vnet中部署不同的子网

时间：2017-08-04 22:55:09

标签： json azure azure-resource-manager azure-virtual-network azure-template

我正在尝试通过模板实现一定程度的容器化。最后，我希望能够在一个模板中定义驻留在虚拟网络和子网（如数据库集群）内的组件（一个或多个服务器）。通过另一个模板，定义一个驻留在虚拟网络和子网内的组件，但可能是另一个组件。

模板A：

  • MY-VNET
    • MY-subnet1
      • 我的接口1

模板B：

  • MY-VNET
    • MY-subnet2
      • 我的接口2

这样，在模板A中嵌套模板B会留给我：

模板AB：

  • MY-VNET
    • MY-subnet1
      • 我的接口1
    • MY-subnet2
      • 我的接口2

相反，我收到以下错误：

New-AzureRmResourceGroupDeployment : 4:56:27 PM - Resource 
 Microsoft.Network/virtualNetworks 'overlayTest-vnet' failed with message '
{
  "error": {
    "code": "InUseSubnetCannotBeDeleted",
    "message": "Subnet overlayTest-subnet2 is in use by  /subscriptions/beep-boop/resourceGroups/d/providers/Microsoft.Network/networkInterfaces/overlayTest-vnet-interface2/ipConfigurations/ipconfig1 and cannot be deleted.",
    "details": []
  }
}

生成的资源组将如下填充（就像部署嵌套模板和嵌套退出后的资源一样）。

模板AB：

  • MY-VNET
    • MY-subnet2
      • 我的接口2

我的模板如下：

答案 0 :(得分：1)

将嵌套模板中的VNet资源更改为子网资源，它将起作用。您要做的是创建一个新的vnet而不是现有的vnet，因此它会尝试更新现有的vnet以匹配您的定义（因此删除所有子网并添加在overlay中定义的1）。

但老实说，整个方法都是错误的，你应该使用属性复制循环并一次完成所有工作。

答案 1 :(得分：0)

最后，我实现了创建嵌套模板的目标，该模板在父模板的虚拟网络中定义了自己的子网，同时保持了在没有父模板的情况下部署嵌套模板的能力。关键是使用条件虚拟网络资源，并确保嵌套模板在嵌套时不会破坏父模板的虚拟网络。感谢@ 4c74356b41让我朝着正确的方向前进。
