在Azure Web App上使用ASP.Net Core在容器上配置AppSettings:冒号冒号? [英] Configuring AppSettings with ASP.Net Core on Azure Web App for Containers: Whither Colons?

问题描述

考虑此appsettings.json:

{
  "Parent": {
    "ChildOne": "C1 from secrets.json",
    "ChildTwo": "C2 from secrets.json"
  }
}

根据Microsoft( https://blogs.msdn.microsoft.com/waws/2018/06/12/asp-net-core-settings-for-azure-app-service/)(如果有应用程序)使用此配置被部署到Azure中的AppService，可以通过在Azure中以样式Parent:ChildOne/Parent:ChildTwo创建应用程序设置来覆盖该配置.需要明确的是:使用冒号来定位特定的配置.

According to Microsoft (https://blogs.msdn.microsoft.com/waws/2018/06/12/asp-net-core-settings-for-azure-app-service/), if an app using this config was deployed to an AppService in Azure, the config could be overwritten by creating Application settings in Azure in the style Parent:ChildOne / Parent:ChildTwo. To be clear: using colons to target a specific piece of config.

这对于标准的AppService可以正常工作:

This works just fine with a standard AppService:

但是，如果您使用Web App for Containers/即将Docker映像部署到Linux上的Azure App Service(

However, if you're using Web App for Containers / i.e. a Docker image deployed to an Azure App Service on Linux (https://docs.microsoft.com/en-us/azure/app-service/containers/app-service-linux-intro) you cannot use colons:

为什么?

将鼠标悬停在错误上时，您会看到以下消息:This field can only contain letters, numbers (0-9), periods ("."), and underscores ("_").使用.无效.

When you hover over the error you see this message: This field can only contain letters, numbers (0-9), periods ("."), and underscores ("_"). Using . does not work alas.

如何在Azure中配置说Parent:ChildOne? Parent.ChildOne不起作用.有人可以建议吗?我找不到关于此的任何文档....

How do you configure say Parent:ChildOne in Azure? Parent.ChildOne does not work. Can anyone advise? I can't find any docs on this....

推荐答案

经过比我想承认的更多实验，

After more experimentation than I'd like to admit I think I have the answer.

在App Service上使用:的地方，请在带有容器的App Service上使用__(双下划线).

Where you use : on an App Service, use a __ (double underscore) on an App Service with containers.

所以Parent__ChildOne而不是Parent:ChildOne.
