ARM 模板 resourceid() 函数失败

Question

请帮助我了解我的 Azure ARM 模板有什么问题，这是非常基本的，需要一些输入参数并打印出 resourceId。

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "virtualNetworkName": {
      "type": "string"
    },
    "virtualNetworkResourceGroupName": {
      "type": "string"
    },
    "subnetName": {
      "type": "string"
    },
    "location": {
      "type": "string",
      "metadata": {
        "description": "Location to Deploy Azure Resources"
      }
    }
  },
  "resources": [],
  "outputs": {
    "subnetRef": {
      "type": "string",
      "value": "[resourceId(parameters('virtualNetworkResourceGroupName'), 'Microsoft.Network/virtualNetworks/subnets', parameters('virtualNetworkName'), parameters('subnetName'))]"
    }
  }
}

提供所需参数时失败并显示以下错误消息。

参数文件

{  
  "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "virtualNetworkName": {
      "value": "core-services-vnet"
    },
    "virtualNetworkResourceGroupName": {
      "value": "core-networking-rg"
    },
    "subnetName": {
      "value": "private"
    },
    "location": {
      "value": "westus"
    }
  }
}

$ az deployment create -n core-deploy --template-file azuredeploy.json --parameters @params.json --location westus

Deployment failed. Correlation ID: b97a7544-2814-40c0-88c9-fbaaea2bf645. The template output 'subnetRef' is not valid: The provided value 'core-networking-rg' is not valid subscription identifier. Please see https://aka.ms/arm-template-expressions/#resourceid for usage details.

我在这里错过了什么？

谢谢，老马

问题是deployment scope。可以将部署定位到 Azure 订阅或订阅中的资源组。

在您的模板中，$schema https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json# 用于资源组部署，而您使用的命令 az deployment create 用于订阅级部署。订阅级部署的架构 https://schema.management.azure.com/schemas/2018-05-01/subscriptionDeploymentTemplate.json# 与资源组部署的架构不同。您可以从 creating resource groups and resources at the subscription level.

获得参考

在这种情况下，您可以使用命令 az group deployment create -n core-deploy --template-file azuredeploy.json --parameters @params.json --location westus 而不是 az deployment create xxx 来解决此问题。
