無法使用 ARM 模板為我的 VMSS 模板計划創建自動縮放屬性

Question

我正在嘗試創建 ARM 模板，以使用上述模板作為參考，在資源中添加縮放屬性，如下所示。 已創建其他資源，但 ARM 無法在我的 VMSS 模板中創建任何類型的自動縮放組。

                                }
                            },
                            {

            }

Answer 1

我可以在這里看到兩個不同的問題：

1) 自動縮放設置的名稱在一個位置是 'AutoScaleSet'，在另一個位置是 'autoscalehost' ：

    {
          "type": "microsoft.insights/autoscalesettings",
          "apiVersion": "2015-04-01",
HERE -->  "name": "AutoScaleSet",             
          "location": "[parameters('location')]",
          "dependsOn": [
            "[resourceId('Microsoft.Compute/virtualMachineScaleSets/', parameters('VMSS_Name'))]"
          ],
          "properties": {
HERE -->    "name": "autoscalehost",
            "targetResourceUri": "[resourceId('Microsoft.Compute/virtualMachineScaleSets/', parameters('VMSS_Name'))]",
            "enabled": true
          }

這需要是相同的值，否則部署失敗並出現以下錯誤：

{
  "code": "BadRequest",
  "message": "The autoscale setting that you provided does not have the same name as the name in the request. Name in autoscale setting: autoscalehost. Name in the request: AutoScaleSet"
}

2) 未向 metricTrigger 規則提供正確的資源 ID

  {
    "metricTrigger": {
    "metricName": "Percentage CPU",
--> "metricResourceUri": "[concat('Microsoft.Compute/virtualMachineScaleSets', parameters('VMSS_Name'))]", <--
    "timeGrain": "PT1M"
  }

您需要在此處獲得完整的資源 ID。 不僅提供者名稱 + VMSS 的名稱。 否則部署將失敗並顯示以下錯誤：

{
  "code": "LinkedInvalidPropertyId",
  "message": "Property id 'Microsoft.Compute/virtualMachineScaleSetssotest' is invalid. Expect fully qualified resource Id that start with '/subscriptions/{subscriptionId}' or '/providers/{resourceProviderNamespace}/'."
}

在模板中使用resourceId()函數代替concat() ，如下所示：

[resourceId('Microsoft.Compute/virtualMachineScaleSets/', parameters('VMSS_Name'))]
