azure-resource-manager - 使用 ARM 模板更新 Azure Function App 时，设置 FUNCTIONS_EXTENSION_VERSION 是否足够？

Question

使用这样的 ARM 模板为我的 Function App 部署资源时

{
  "type": "Microsoft.Web/sites",
  "kind": "functionapp",
  "name": "[parameters('appNameFunctions')]",
  "apiVersion": "2015-08-01",
  "location": "West Europe",
  "tags": {},
  "properties": {
    "name": "[parameters('appNameFunctions')]",
    "serverFarmId": "[resourceId('Microsoft.Web/serverfarms', parameters('aspNameFunctions'))]"
  },
  "resources": [
    {
      "name": "appsettings",
      "type": "config",
      "apiVersion": "2015-08-01",
      "dependsOn": [
        "[concat('Microsoft.Web/sites/', parameters('appNameFunctions'))]"
      ],
      "tags": {
        "displayName": "fnAppSettings"
      },
      "properties": {
        "AzureWebJobsStorage":"[concat('DefaultEndpointsProtocol=https;AccountName=',parameters('storageAccountNameFunctions'),';AccountKey=',listKeys(resourceId('Microsoft.Storage/storageAccounts', parameters('storageAccountNameFunctions')), '2015-05-01-preview').key1)]",
        "AzureWebJobsDashboard":"[concat('DefaultEndpointsProtocol=https;AccountName=',parameters('storageAccountNameFunctions'),';AccountKey=',listKeys(resourceId('Microsoft.Storage/storageAccounts', parameters('storageAccountNameFunctions')), '2015-05-01-preview').key1)]",
        "WEBSITE_CONTENTAZUREFILECONNECTIONSTRING":"[concat('DefaultEndpointsProtocol=https;AccountName=',parameters('storageAccountNameFunctions'),';AccountKey=',listKeys(resourceId('Microsoft.Storage/storageAccounts', parameters('storageAccountNameFunctions')), '2015-05-01-preview').key1)]",
        "WEBSITE_CONTENTSHARE":"[parameters('appNameFunctions')]",
        "FUNCTIONS_EXTENSION_VERSION":"~0.8",
        "AZUREJOBS_EXTENSION_VERSION":"beta",
        "WEBSITE_NODE_DEFAULT_VERSION":"6.5.0"
      }
    }
  ],
  "dependsOn": [
    "[resourceId('Microsoft.Web/serverfarms', parameters('aspNameFunctions'))]",
    "[resourceId('Microsoft.Storage/storageAccounts', parameters('storageAccountNameFunctions'))]"
  ]
}

设置 FUNCTIONS_EXTENSION_VERSION就够了吗？到所需的版本，应用服务会自动调整/加载正确的运行时还是需要调整或执行其他内容？

是的，这就足够了，这正是当您单击按钮升级应用程序时 Portal 所做的事情。

另一种选择是将其设置为“最新”，这意味着它将始终使用最新的。尽管这样做的风险会受到重大更改的影响。
