具有带有多个订阅的主题的Service Bus的Azure ARM模板

Question

嗨，我有一个用于创建带有主题和订阅的ServiceBus的ARM模板。但是我只能完成1个主题-1个订阅，因为我无法进行嵌套循环来为每个主题创建多个订阅。

我希望我可以执行这样的模板：

参数：

{
   "serviceBusName": "mybus",
   "topics": 
    [ 
      { 
         "topicName": "mytopic1",
         "subscriptions": [ "mysubscription1", "mysubscription2"]
      },
      { 
         "topicName": "mytopic2",
         "subscriptions": [ "mysubscription1"]
      }  
    ]
}

这是我的实际模板：

{
  "$schema": "http://schema.management.azure.com/schemas/2014-04-01-preview/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {

    },
    {

      "dependsOn": [

      ],
      "resources": [
        {
          "apiVersion": "[variables('sbVersion')]",
          "name": "[parameters('Topics')[copyIndex()].subscription]",
          "type": "Subscriptions",
          "dependsOn": [
            "[parameters('Topics')[copyIndex()].topic]"
          ],
          "properties": {
            "lockDuration": "PT1M",
            "requiresSession": "false",
            "defaultMessageTimeToLive": "P7D",
            "deadLetteringOnMessageExpiration": "false",
            "maxDeliveryCount": "2",
            "enableBatchedOperations": "true",
            "autoDeleteOnIdle": "P7D"
          }
        }
      ]
    }
  ],
  "outputs": {
    "NamespaceDefaultConnectionString": {
      "type": "string",
      "value": "[listkeys(variables('DefaultAuthRuleResourceId'), variables('SbVersion')).primaryConnectionString]"
    },
    "DefaultSharedAccessPolicyPrimaryKey": {
      "type": "string",
      "value": "[listkeys(variables('DefaultAuthRuleResourceId'), variables('SbVersion')).primaryKey]"
    }
  }
}

以及实际模板的params json的示例：

{
    "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentParameters.json#",
    "contentVersion": "1.0.0.0",
    "parameters": {
        "ServiceBusNamespaceName": {
            "value": "mybus"
        },
        "ServiceBusSku": {
            "value": "Standard"
        },
        "Topics ": {
            "value": [
                {
                    "topic": "mytopic1",
                    "subscription": "mysubscription1"
                },
                {
                    "topic": "mytopic2",
                    "subscription": "mysubscription1"
                }
            ]
        }
    }
}

一般来说，有两种方法可以完成这样的事情。您可以重组代码，使订阅成为顶级资源。或者您使用 的命名变体copyIndex来实现嵌套循环。这两种变体都可以在这篇博文及其评论中看到。

Azure ARM 模板 \xe2\x80\x93 是否可以嵌套循环？

\n\n

但是，对于您的情况，唯一的选择是将订阅设为顶级资源。有关更多详细信息，请参阅aka.ms/arm-copy/#looping-on-a-nested-resource 。

此虚拟机示例使用命名copyIndex- 当嵌套循环不适用于资源本身时，它会起作用。

\n\n

{\n  "name": "[concat(parameters(\'vmName\'), padLeft(copyIndex(1), 2, \'0\'))]",\n  "type": "Microsoft.Compute/virtualMachines",\n  "copy": {\n    "name": "vmLoop",\n    "count": "[parameters(\'vmCount\')]"\n  },\n  "properties": {\n    "osProfile": {\n      "computerName": "[concat(parameters(\'vmName\'), padLeft(copyIndex(1), 2, \'0\'))]"\n    },\n    "hardwareProfile": {\n      "vmSize": "[parameters(\'vmSize\')]"\n    },\n    "storageProfile": {\n      "osDisk": {\n        "name": "[concat(parameters(\'vmName\'), padLeft(copyIndex(1), 2, \'0\'),\'_OSDisk\')]",\n        "createOption": "FromImage",\n        "managedDisk": {\n          "storageAccountType": "[parameters(\'vmDiskType\')]"\n        }\n      },\n      "copy": [\n        {\n          "name": "dataDisks",\n          "count": "[parameters(\'dataDiskCount\')]",\n          "input": {\n            "caching": "[parameters(\'dataDiskCaching\')]",\n            "name": "[concat(parameters(\'vmName\'), padLeft(copyIndex(\'vmLoop\', 1), 2, \'0\'), \'-dataDisk\', padLeft(copyIndex(\'dataDisks\'), 2, \'0\'))]",\n            "lun": "[copyIndex(\'dataDisks\')]",\n            "createOption": "Empty",\n            "diskSizeGB": "[parameters(\'dataDiskSize\')]",\n            "managedDisk": {\n              "storageAccountType": "[parameters(\'vmDiskType\')]"\n            }\n          }\n        }\n      ]\n    }\n  }\n}\n
