Azure Policy 存储帐户保留策略未标记资源

【中文标题】Azure Policy 存储帐户保留策略未标记资源

【英文标题】：Azure Policy Storage Accounts retention policy not flagging the resource

【发布时间】：2020-09-28 19:02:36

【问题描述】：

我正在使用下面的代码来监控存储帐户的保留策略。似乎我有正确的别名，但是当我看到合规性报告时显示“100% 合规 0 出 0”。版本控制和私有链接策略也有同样的问题。我有与这些类似的存储帐户策略，但它们实际上返回目标存储帐户的数量，唯一的区别是它们没有像这些那样引用 blob 服务别名。感谢您的任何回答。

添加此代码以使策略正常工作。

    "mode": "All",
    "policyRule": 
        "if": 
            "field": "type",
            "equals": "Microsoft.Storage/storageAccounts"
        ,
        "then": 
            "effect": "auditIfNotExists",
            "details":

                    "/providers/microsoft.authorization/roleDefinitions/b24988ac-6180-42a0-ab88-20f7382dd24c"

【参考方案1】：

似乎是 Azure 中的这个 ia 错误，记录在这里：https://github.com/Azure/azure-policy/issues/377。显然 Microsoft.Storage/storageAccounts/blobServices 尚未运行。解决方案的 ETA 表示 2020 年 9 月，但该日期和之前的一些日期已经过去。

【讨论】：

能否确保通过 Azure 策略为 blob 启用软删除？

现在可以在 roleDefinitons 的帮助下完成，请参阅上面的代码。

【参考方案2】：

任何引用 Microsoft.Storage/storageAccounts/blobServices 的策略都应使用以下代码正常工作。（删除保留、版本控制等） 现在可以使用以下策略：

    "mode": "All",
    "policyRule": 
        "if": 
            "field": "type",
            "equals": "Microsoft.Storage/storageAccounts"
        ,
        "then": 
            "effect": "auditIfNotExists",
            "details": 
                "type": "Microsoft.Storage/storageAccounts/blobServices",
                "roleDefinitionIds": [
                    "/providers/microsoft.authorization/roleDefinitions/b24988ac-6180-42a0-ab88-20f7382dd24c"
                ],
                "existenceCondition": 
                    "field": "Microsoft.Storage/storageAccounts/blobServices/deleteRetentionPolicy.enabled",
                    "equals": "true"
