在将 Application Insights 与我的 Web 应用程序部署到 Azure 时，我遇到了先有鸡还是先有蛋的问题。在 ARM 模板中，Application Insights 模块依赖于应用程序 ID 的网站（请参阅下面的 ARM 模板中的依赖项）。另一方面，为了全面检测 Web 应用程序，我需要来自 Application Insights 模块的检测密钥。如何解决这个问题？
门户中的 Application Insights 视图
Web 应用的 ARM 模板
Application Insights 的 ARM 模板
解决方案是将连接字符串和应用程序设置创建为网站的嵌套子资源。通过使用子资源策略，可以使 appsettings 依赖于网站和应用程序的洞察力。这允许按以下顺序进行配置：
以下两个答案很有帮助。第一个说明了如何拉动仪表键。第二个说明了如何将应用程序设置和连接字符串嵌套为网站的子资源。
这是我的最终模板：

替代和更新的答案 (2020/03)：执行 Azure Portal UX 所做的事情（可以在 webapp 创建的最后一步通过“下载模板”查看）。
对于应用程序洞察资源，您不一定需要等待创建网站资源。根据 applicationInsights ARM 的website.Name习惯applicaitonInsights.properties.ApplicationId。由于您同时创建两者，因此您可以将名称值从输入中传递给 ApplicationInsights 和网站资源：

创建顺序如下：
要详细说明 Mikl X 答案，您可以让网站依赖于应用程序洞察资源并在网站的应用程序设置上设置检测密钥。
