如何使用 ARM 模板创建多个服务总线主题？

Question

我查看了https://github.com/Azure/azure-quickstart-templates/tree/master/101-servicebus-topic 示例。现在我试图弄清楚如何在使用嵌套资源循环 (https://azure.microsoft.com/en-us/documentation/articles/resource-group-create-multiple/#looping-on-a-nested-resource) 运行部署脚本时创建多个主题。

最好在serviceBusTopicName 的值中定义一个数组，然后以某种方式通过循环创建主题，而不是手动执行。

我在尝试部署时收到以下错误。

 Error: Code=InvalidTemplate; Message=Deployment template validation failed: 'The template resource '[parameters('serviceBusTopicName')[copyIndex()]]' at line '72' column '14' is not valid.
 Copying nested resources is not supported. Please see https://aka.ms/arm-copy/#looping-on-a-nested-resource for usage details.'.

这是我试图开始工作的template.json。

  "parameters": {
"serviceBusNamespaceName": {
  "type": "string",
  "metadata": {
    "description": "Name of the Service Bus namespace"
  }
},
"serviceBusTopicName": {
  "type": "array",
  "metadata": {
    "description": "Name of the Topic"
  }
},
"serviceBusApiVersion": {
  "type": "string",
  "defaultValue": "2015-08-01",
  "metadata": {
    "description": "Service Bus ApiVersion used by the template"
  },
  "resources": [
{
  "apiVersion": "[variables('sbVersion')]",
  "name": "[parameters('serviceBusNamespaceName')]",
  "type": "Microsoft.ServiceBus/Namespaces",
  "location": "[variables('location')]",
  "kind": "Messaging",
  "sku": {
    "name": "StandardSku",
    "tier": "Standard"
  },
  "resources": [
    {
      "apiVersion": "[variables('sbVersion')]",
      "name": "[parameters('serviceBusTopicName')]",
      "type": "Topics",
      "dependsOn": [
        "[concat('Microsoft.ServiceBus/namespaces/', parameters('serviceBusNamespaceName'))]"
      ],
      "properties": {
        "path": "[parameters('serviceBusTopicName')]"
      },
      "copy": {
        "name": "datasetcopy",
        "count": "[length(parameters('serviceBusTopicName'))]"
      }
    }
  ]
},

parameters.json

      "Stadium",
      "Team"
    ]
  },
    "serviceBusApiVersion": {
        "value": "2015-08-01"
    }
}

正如@Lain 所说，目前Check Here 不支持复制嵌套资源。要部署多个资源，您必须将其移至根目录。我刚刚完成了部署多个主题的 POC（假设命名空间已经存在的只是主题）这里是代码。我将主题名称作为逗号分隔的字符串传递：

{
"$schema": "http://schema.management.azure.com/schemas/2014-04-01-preview/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
    "serviceBusNamespaceName": {
        "type": "string",
        "metadata": {
            "description": "Name of the Service Bus namespace"
        }
    },
    "serviceBusTopicName": {
        "type": "string",
        "metadata": {
            "description": "Comma seperated Topic Names"
        }
    },
    "serviceBusApiVersion": {
        "type": "string",
        "defaultValue": "2015-08-01",
        "metadata": {
            "description": "Service Bus ApiVersion used by the template"
        }
    }
},
"variables": {
    "location": "[resourceGroup().location]",
    "sbVersion": "[parameters('serviceBusApiVersion')]",
    "TopicNames": "[split(parameters('serviceBusTopicName'), ',')]"
},
"resources": [{
    "apiVersion": "[variables('sbVersion')]",
    "name": "[concat(parameters('serviceBusNamespaceName'), '/', variables('TopicNames')[copyIndex()])]",
    "type": "Microsoft.ServiceBus/Namespaces/Topics",
    "copy": {
        "name": "TopicNameCopy",
        "count": "[length(variables('TopicNames'))]"
    },
    "properties": {
        "path": "[variables('TopicNames')[copyIndex()]]"
    }
}]
}

错误消息中的链接很好地解决了这个问题，但是嵌套资源中不能有循环，您需要将资源推送到顶层，然后使用名称将资源链接在一起。这个模板会做你想做的事：

{
  "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "serviceBusNamespaceName": {
      "type": "string",
      "metadata": {
        "description": "Name of the Service Bus Namespace"
      }
    },
    "serviceBusTopicNames": {
      "type": "array",
      "metadata": {
        "description": "Name of the Service Bus Topic"
      }
    }
  },
  "variables": {
    "sbVersion": "2015-08-01"
  },
  "resources": [
    {
      "apiVersion": "[variables('sbVersion')]",
      "name": "[parameters('serviceBusNamespaceName')]",
      "type": "Microsoft.ServiceBus/namespaces",
      "location": "[resourceGroup().location]",
      "properties": {
      }
    },
    {
      "apiVersion": "[variables('sbVersion')]",
      "name": "[concat(parameters('serviceBusNamespaceName'), '/',  parameters('serviceBusTopicNames')[copyIndex()])]",
      "type": "Microsoft.ServiceBus/namespaces/Topics",
      "dependsOn": [
        "[concat('Microsoft.ServiceBus/namespaces/', parameters('serviceBusNamespaceName'))]"
      ],
      "copy": {
        "name": "datasetcopy",
        "count": "[length(parameters('serviceBusTopicNames'))]"
      },
      "properties": {
        "path": "[parameters('serviceBusTopicNames')[copyIndex()]]"
      },
      "resources": [
      ]
    }
  ]
}
