附加标签策略不适用于某些资源

Question

我正在创建一个 Azure 策略来将标签附加到新创建的资源，它适用于大多数组件，但我发现此策略不适用于某些组件，例如：逻辑应用程序。

{
  "mode": "All",
  "parameters": {
    "Environment": {
      "type": "String",
      "metadata": {
        "displayName": "Environment"
      },
      "defaultValue": "dev"
    },
    "Owner": {
      "type": "String",
      "metadata": {
        "displayName": "Owner"
      },
      "defaultValue": "Admin"
    },
    "CostCenter": {
      "type": "String",
      "metadata": {
        "displayName": "CostCenter"
      },
      "defaultValue": "NA"
    }
  },
  "policyRule": {
    "if": {
      "field": "tags",
      "exists": "false"
    },
    "then": {
      "effect": "append",
      "details": [
        {
          "field": "tags",
          "value": {
            "Environment": "[parameters('Environment')]",
            "Owner": "[parameters('Owner')]",
            "CostCenter": "[parameters('CostCenter')]"
          }
        }
      ]
    }
  }
}

我添加了一个类似的策略来将标签应用到资源组，但根本不起作用，我不知道发生了什么。

{
  "mode": "All",
  "parameters": {
    "Environment": {
      "type": "String",
      "metadata": {
        "displayName": "Environment"
      },
      "defaultValue": "dev"
    },
    "Owner": {
      "type": "String",
      "metadata": {
        "displayName": "Owner"
      },
      "defaultValue": "admin"
    },
    "CostCenter": {
      "type": "String",
      "metadata": {
        "displayName": "CostCenter"
      },
      "defaultValue": "NA"
    }
  }
  "policyRule": {
    "if": {
      "allOf": [
        {
          "field": "tags",
          "exists": "false"
        },
        {
          "field": "type",
          "equals": "Microsoft.Resources/subscriptions/resourceGroups"
        }
      ]
    },
    "then": {
      "effect": "append",
      "details": [
        {
          "field": "tags",
          "value": {
            "Environment": "[parameters('Environment')]",
            "Owner": "[parameters('Owner')]",
            "CostCenter": "[parameters('CostCenter')]"
          }
        }
      ]
    }
  }
}

Answer 1

我自己弄清楚，我策略中的 "exists": "false" 条件只会在 "tags" 属性缺失或为空时触发，因此具有 [= 的资源组或资源13=] 将绕过我的政策，即使它没有任何标签。

此外，简单的标签检查是不合理的，应该通过标签名称逐一检查，如果不符合，则采取行动追加。

而且我还发现以下声明不适用于资源组，可能是因为它是不规范的做法。

{
  "then": {
    "effect": "append",
    "details": [
      {
        "field": "tags",
        "value": {
          "Environment": "[parameters('Environment')]",
          "Owner": "[parameters('Owner')]",
          "CostCenter": "[parameters('CostCenter')]"
        }
      }
    ]
  }
}

建议改用下面的语句

{
  "then": {
    "effect": "append",
    "details": [
      {
        "field": "tags['Environment']",
        "value": "[parameters('Environment')]"
      },
      {
        "field": "tags['Owner']",
        "value": "[parameters('Owner')]"
      },
      {
        "field": "tags['CostCenter']",
        "value": "[parameters('CostCenter')]"
      }
    ]
  }
}
