Question

我正在尝试使用此Azure Resource Manager模板代码段将自定义域添加到一组webapps。正在创建Web应用程序，流量管理器配置文件也是如此。但是，添加自定义主机名时，ARM模板失败。请注意，我正在使用传递给模板的变量参数来创建网站。

    {
      "name": "[concat(parameters('webAppNamePrefix'), '-', uniqueString(resourceGroup().id), '-site-', copyIndex())]",
      "type": "Microsoft.Web/sites",

      "apiVersion": "2016-08-01",
      "copy": {
        "count": "[length(parameters('webAppLocations'))]",
        "name": "siteCopy"
      },
      "dependsOn": [
        "farmCopy"
      ],
      "resources": [
        {
          "name": "appsettings",
          "type": "config",
          "apiVersion": "2016-08-01",
          "dependsOn": [
            "[concat(parameters('webAppNamePrefix'), '-', uniqueString(resourceGroup().id), '-site-', copyIndex())]"
          ],

          },
          "properties": {
            "publishingUsername": "[variables('publishingUsername')]",
            "DOCKER_CUSTOM_IMAGE_NAME": "[parameters('dockerImageName')]"
          }
        }
      ],
      "tags": {
        "[concat('hidden-related:', resourceId('Microsoft.Web/serverfarms', concat(parameters('webAppNamePrefix'), '-', uniqueString(resourceGroup().id))), '-', copyIndex())]": "Resource",
        "displayName": "[concat(parameters('webAppNamePrefix'), '-', uniqueString(resourceGroup().id), '-site-', copyIndex())]"
      },

        "serverFarmId": "[resourceId('Microsoft.Web/serverfarms', concat(parameters('webAppNamePrefix'), '-', uniqueString(resourceGroup().id), '-', copyIndex()))]"
      }
    },
    {
      "type": "Microsoft.Web/sites/hostnameBindings",
      "name": "[concat(parameters('webAppNamePrefix'), '-', uniqueString(resourceGroup().id), '-site-', copyIndex(), '/', parameters('customHostname'))]",
      "apiVersion": "2016-08-01",
      "location": "[resourceGroup().location]",
      "properties": {
      },
      "dependsOn": [
        "[concat('Microsoft.Web/sites/',parameters('webAppNamePrefix'), '-', uniqueString(resourceGroup().id), '-site-', copyIndex(), '/', parameters('customHostname'))]"
      ]
    }

请注意，copyIndex（）适用于模板中其他位置的网站名称。那么为什么它不适用于“Microsoft.Web / sites / hostnameBindings”部分呢？我很难过。

以下是参数。请注意webAppLocations参数是一个数组。

"parameters": {
    "webAppNamePrefix": {
      "type": "string",
      "minLength": 1
    },
    "dockerImageName": {
      "type": "string",
      "metadata": {
        "description": "Name of docker image to use"
      }
    },
    "farmSkuName": {
      "type": "string",
      "metadata": {
        "description": "Describes plan's pricing tier and capacity. Check details at https://azure.microsoft.com/en-us/pricing/details/app-service/"
      }
    },
    "environmentType": {
      "type": "string",
      "allowedValues": [
        "dev",
        "qa",
        "prod"
      ],
      "metadata": {
        "description": "Environment type name"
      }
    },
    "webAppLocations": {
      "type": "array"
    },
    "trafficManagerPrefix": {
      "type": "string"
    },
    "customHostname": {
      "type": "string",
      "metadata": {
          "description": "The custom hostname that you wish to add."
      }
    }    
  },

你永远不应该在resources属性之后放置任何东西，不是因为它破坏了模板，而是因为它更难以查看它。在您的情况下，您将Microsoft.Web/sites/hostnameBindings置于资源之外。

{
    "name": "[concat(parameters('webAppNamePrefix'), '-', uniqueString(resourceGroup().id), '-site-', copyIndex())]",
    "type": "Microsoft.Web/sites",
    "kind": "app,linux,container",
    "location": "[parameters('webAppLocations')[copyIndex()]]",
    "apiVersion": "2016-08-01",
    "copy": {
        "count": "[length(parameters('webAppLocations'))]",
        "name": "siteCopy"
    },
    "dependsOn": [
        "farmCopy"
    ],
    "tags": {
        "[concat('hidden-related:', resourceId('Microsoft.Web/serverfarms', concat(parameters('webAppNamePrefix'), '-', uniqueString(resourceGroup().id))), '-', copyIndex())]": "Resource",
        "displayName": "[concat(parameters('webAppNamePrefix'), '-', uniqueString(resourceGroup().id), '-site-', copyIndex())]"
    },
    "properties": {
        "name": "[concat(parameters('webAppNamePrefix'), '-', uniqueString(resourceGroup().id), '-site-', copyIndex())]",
        "serverFarmId": "[resourceId('Microsoft.Web/serverfarms', concat(parameters('webAppNamePrefix'), '-', uniqueString(resourceGroup().id), '-', copyIndex()))]"
    },
    "resources": [
        {
            "name": "appsettings",
            "type": "config",
            "apiVersion": "2016-08-01",
            "dependsOn": [
                "[concat(parameters('webAppNamePrefix'), '-', uniqueString(resourceGroup().id), '-site-', copyIndex())]"
            ],
            "tags": {
                "displayName": "Application settings"
            },
            "properties": {
                "publishingUsername": "[variables('publishingUsername')]",
                "DOCKER_CUSTOM_IMAGE_NAME": "[parameters('dockerImageName')]"
            }
        },
        {
            "type": "hostnameBindings",
            "name": "[parameters('customHostname')]",
            "apiVersion": "2016-08-01",
            "location": "[resourceGroup().location]",
            "properties": {},
            "dependsOn": [
                "[concat('Microsoft.Web/sites/',parameters('webAppNamePrefix'), '-', uniqueString(resourceGroup().id), '-site-', copyIndex(), '/', parameters('customHostname'))]"
            ]
        }
    ]
}
