在 ARM 模板中设置扩展资源的范围

  • 项目

扩展资源是用于修改其他资源的资源。 例如，可以为资源分配角色。 角色分配是扩展资源类型。

有关扩展资源类型的完整列表，请参阅用于扩展其他资源的功能的资源类型。

本文介绍如何在使用 Azure 资源管理器模板（ARM 模板）进行部署时设置扩展资源类型的范围。 它介绍了在应用到资源时可用于扩展资源的 scope 属性。

注意

scope 属性仅适用于扩展资源类型。 若要为非扩展类型的资源类型指定其他范围，请使用嵌套部署或链接部署。 有关详细信息，请参阅资源组部署、订阅部署、管理组部署和租户部署。

在部署范围内应用

若要在目标部署范围内应用扩展资源类型，请将该资源添加到模板中，就像应用任何资源类型一样。 可用的范围是资源组、订阅、管理组和租户。 部署范围必须支持该资源类型。

以下模板会部署一个锁。

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
  },
  "resources": [
    {
      "type": "Microsoft.Authorization/locks",
      "apiVersion": "2016-09-01",
      "name": "rgLock",
      "properties": {
        "level": "CanNotDelete",
        "notes": "Resource Group should not be deleted."
      }
    }
  ]
}

部署到资源组时，它会锁定资源组。

az deployment group create \
  --resource-group ExampleGroup \
  --template-uri "https://raw.githubusercontent.com/Azure/azure-docs-json-samples/master/azure-resource-manager/scope/locktargetscope.json"

下一个示例会分配角色。

{
  "$schema": "https://schema.management.azure.com/schemas/2018-05-01/subscriptionDeploymentTemplate.json#",
  "contentVersion": "1.0.0.1",
  "parameters": {
    "principalId": {
      "type": "string",
      "metadata": {
        "description": "The principal to assign the role to"
      }
    },
    "builtInRoleType": {
      "type": "string",
      "allowedValues": [
        "Owner",
        "Contributor",
        "Reader"
      ],
      "metadata": {
        "description": "Built-in role to assign"
      }
    },
    "roleNameGuid": {
      "type": "string",
      "metadata": {
        "description": "The role assignment name"
      }
    }
  },
  "variables": {
    "Owner": "[concat('/subscriptions/', subscription().subscriptionId, '/providers/Microsoft.Authorization/roleDefinitions/', '8e3af657-a8ff-443c-a75c-2fe8c4bcb635')]",
    "Contributor": "[concat('/subscriptions/', subscription().subscriptionId, '/providers/Microsoft.Authorization/roleDefinitions/', 'b24988ac-6180-42a0-ab88-20f7382dd24c')]",
    "Reader": "[concat('/subscriptions/', subscription().subscriptionId, '/providers/Microsoft.Authorization/roleDefinitions/', 'acdd72a7-3385-48ef-bd42-f606fba81ae7')]"
  },
  "resources": [
    {
      "type": "Microsoft.Authorization/roleAssignments",
      "apiVersion": "2020-10-01-preview",
      "name": "[parameters('roleNameGuid')]",
      "properties": {
        "roleDefinitionId": "[variables(parameters('builtInRoleType'))]",
        "principalId": "[parameters('principalId')]"
      }
    }
  ],
  "outputs": {}
}

部署到订阅时，它会为订阅分配角色。

az deployment sub create \
  --name demoSubDeployment \
  --location chinaeast \
  --template-uri "https://raw.githubusercontent.com/Azure/azure-docs-json-samples/master/azure-resource-manager/scope/roletargetscope.json"

应用于资源

若要将扩展资源应用于资源，请使用 scope 属性。 将 scope 属性设置为要将扩展添加到其中的资源的名称。 scope 属性是扩展资源类型的根属性。

下面的示例创建一个存储帐户并对其应用角色。

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "principalId": {
      "type": "string",
      "metadata": {
        "description": "The principal to assign the role to"
      }
    },
    "builtInRoleType": {
      "type": "string",
      "allowedValues": [
        "Owner",
        "Contributor",
        "Reader"
      ],
      "metadata": {
        "description": "Built-in role to assign"
      }
    },
    "roleNameGuid": {
      "type": "string",
      "defaultValue": "[newGuid()]",
      "metadata": {
        "description": "A new GUID used to identify the role assignment"
      }
    },
    "location": {
      "type": "string",
      "defaultValue": "[resourceGroup().location]"
    }
  },
  "variables": {
    "Owner": "[concat('/subscriptions/', subscription().subscriptionId, '/providers/Microsoft.Authorization/roleDefinitions/', '8e3af657-a8ff-443c-a75c-2fe8c4bcb635')]",
    "Contributor": "[concat('/subscriptions/', subscription().subscriptionId, '/providers/Microsoft.Authorization/roleDefinitions/', 'b24988ac-6180-42a0-ab88-20f7382dd24c')]",
    "Reader": "[concat('/subscriptions/', subscription().subscriptionId, '/providers/Microsoft.Authorization/roleDefinitions/', 'acdd72a7-3385-48ef-bd42-f606fba81ae7')]",
    "storageName": "[concat('storage', uniqueString(resourceGroup().id))]"
  },
  "resources": [
    {
      "type": "Microsoft.Storage/storageAccounts",
      "apiVersion": "2021-04-01",
      "name": "[variables('storageName')]",
      "location": "[parameters('location')]",
      "sku": {
        "name": "Standard_LRS"
      },
      "kind": "Storage",
      "properties": {}
    },
    {
      "type": "Microsoft.Authorization/roleAssignments",
      "apiVersion": "2020-10-01-preview",
      "name": "[parameters('roleNameGuid')]",
      "scope": "[concat('Microsoft.Storage/storageAccounts', '/', variables('storageName'))]",
      "dependsOn": [
        "[variables('storageName')]"
      ],
      "properties": {
        "roleDefinitionId": "[variables(parameters('builtInRoleType'))]",
        "principalId": "[parameters('principalId')]"
      }
    }
  ]
}

resourceGroup 和订阅属性仅可用于嵌套或链接部署。 在单个资源上不允许使用这些属性。 如果要部署其范围设置为其他资源组中资源的扩展资源，请使用嵌套或链接部署。
