无法使用 ARM 模板为我的 VMSS 模板计划创建自动缩放属性

Question

我正在尝试创建 ARM 模板以根据以下使用上述模板作为参考在 Resources 中添加缩放属性。已创建其他资源，但 ARM 无法在我的 VMSS 模板中创建任何类型的自动缩放组。

                    }
                ]
            }
        }

Answer 1

我可以在这里看到两个不同的问题：

1) 自动缩放设置的名称在一个位置是 'AutoScaleSet'，在另一个位置是 '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
          }

这需要是相同的值，否则部署会失败并出现以下错误：

{
  "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) 没有向 metricTrigger 规则提供正确的资源 ID

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

您需要此处的完整资源 ID。不仅提供者名称 + VMSS 名称。否则部署将失败并出现以下错误：

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

在您的模板中使用 resourceId() 函数代替 concat()，如下所示：

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