如何在 ARM 模板中动态生成流量管理器终结点？

Question

我有一个 ARM 模板，它使用 copy 构造创建任意数量的 Azure webapps，就像这样（删除了不相关的部分）：

{
  "parameters": { 
    "numWebsites": {
      "type": "int",
      "defaultValue": 2
    }
  },
  "resources": [
    "name": "[concat('webapp-', copyIndex()]",
    "type": "Microsoft.Web/sites",
    "copy": {
      "name": "websitescopy",
      "count": "[parameters('numWebsites')]"
    }
  ]
}

我还想为创建的每个网站创建一个带有端点的流量管理器配置文件。但是，似乎没有办法在流量管理器资源的 endpoints 参数中使用 copy。我见过的所有示例都有端点 explicitly listed out，但我不知道提前创建了多少 Web 应用程序，所以这对我不起作用。

如何在我的模板中动态生成端点？我试过在 trafficManagerProfiles 资源中使用 copy 语句，但这会创建多个配置文件，每个配置文件都有一个端点。

Answer 1

这是一个创建外部端点的示例 "child resource"，配置文件是单独创建的，没有任何端点，然后此资源添加端点。它使用外部端点，但对于 webapp 应该同样有效，并且与标准复制功能兼容。

    }

Answer 2

我还没有对此进行测试，但看来 copy/copyIndex 现在应该是流量管理器端点的受支持方案：

这是我不久前实现的示例：

我不清楚接受的答案，到目前为止 Paul 的答案仅提供了部分示例。在故障排除期间，我遇到了另一个与名称段长度相关的错误，这不容易理解，所以这是我的工作解决方案（non-relevant 部分也被删除）：

    {
  "type": "Microsoft.Network/trafficManagerProfiles",
  "apiVersion": "2017-05-01",
  "location": "global",
  "name": "[variables('trafManagerProfileName')]",
  "properties": { ...}
},
{
  "apiVersion": "2015-11-01",
  "type": "Microsoft.Network/trafficManagerProfiles/ExternalEndpoints",
  "name": "[concat(variables('trafManagerProfileName'), '/Endpoint', copyIndex())]",
  "dependsOn": [
    "[concat('Microsoft.Network/trafficManagerProfiles/', variables('trafManagerProfileName'))]",
    "[concat(parameters('app_name')[copyIndex()])]"
  ],
  "location": "global",
  "properties": {
    "target": "[concat(parameters('app_name')[copyIndex()])]"        
  },
  "copy": {
    "count": "[variables('app_count')]",
    "name": "app_copy"
  }
},
{
  "type": "Microsoft.Web/sites",
  "name": "[concat(parameters('app_name')[copyIndex()])]",
  "copy": {
    "count": "[variables('app_count')]",
    "name": "app_copy"
  }
}

您可以参考以下模板添加流量管理端点并启用复制。

Azure 不提供在副本中添加端点的功能，因此您需要创建一个单独的资源并将其 link 到原始资源以添加端点。这样模板内部就支持复制功能了。

"resources": [
    {
      "apiVersion": "2017-05-01",
      "type": "Microsoft.Network/trafficManagerProfiles",
      "name": "[parameters('resourceName')]",
      "location": "global",
      "properties": {
        "profileStatus": "Enabled",
        "trafficRoutingMethod": "Performance",
        "dnsConfig": {
          "relativeName": "[parameters('uniqueDnsName')]",
          "ttl": "[parameters('timeToLive')]"
        },
        "monitorConfig": {
          "protocol": "[parameters('protocol')]",
          "port": "[parameters('portName')]",
          "path": "[parameters('pathName')]",
          "intervalInSeconds": "[parameters('monitorIntervalInSeconds')]",
          "timeoutInSeconds": "[parameters('monitorTimeoutInSeconds')]",
          "toleratedNumberOfFailures": "[parameters('toleratedNumberOfFailures')]"
        }
      }
    },
    {
      "apiVersion": "2017-05-01",
      "type": "Microsoft.Network/trafficManagerProfiles/azureEndpoints",
      "dependsOn": [
        "Microsoft.Network/trafficManagerProfiles/ExampleTMProfile"
      ],
      "location": "global",
      "name": "[concat('ExampleTMProfile/Endpoint', copyIndex())]",
      "copy": {
        "name": "azureEndpointsCopy",
        "count": "[length(parameters('azureEndpointNameArray'))]"
      },
      "properties": {
        "targetResourceId": "[resourceId('Microsoft.Network/publicIPAddresses', parameters('azureEndpointNameArray')[copyIndex()])]",
        "endpointStatus": "Enabled"
      }
    }
  ]
