azure - 部署 Azure 防火墙 IP 组更改失败并出现冲突

问题描述

我正在尝试使用策略、规则和一组 IPGroup 部署 Azure 防火墙。当我部署 ARM 模板以开始一切正常时。稍后如果我想更改其中一个 IPGroup 中的某些内容，并尝试部署该 IPGroup 更改，Azure 部署将失败并显示状态：与消息冲突：

{
    "status": "Failed",
    "error": {
        "code": "ResourceDeploymentFailure",
        "message": "The resource operation completed with terminal provisioning state 'Failed'."
    }
}

我尝试在他们自己的 ARM 模板中明确管理 IPGroups，并将它们与 Azure Policy Rule Collection ARM Template 和 DependsOn 一起放置，看看将它们全部部署在一起是否会有所帮助，但无论哪种方式，我们都会得到“冲突” .. 我想我想知道更新作为防火墙网络规则一部分的 IPGroup 的适当方法是什么？如果我不能简单地更新 IPGroup？

这是我的带有 IPGroups 的策略的完整 ARM 模板的示例。

解决方案

需要一次部署一个 IP 组。此外，防火墙策略需要依赖于正在使用的 IP 组，尽管它没有列出它们。

IP 组的部署似乎在部署期间对防火墙策略进行了一些验证/更新。
