我正在尝试使用将X-Forwarded-For请求标头添加到mcr.microsoft.com/dotnet/framework/aspnet:4.8-windowsservercore-ltsc2019Docker 基础映像中Add-WebConfigurationProperty。

我的 Dockerfile 看起来像：

FROM mcr.microsoft.com/dotnet/framework/aspnet:4.8-windowsservercore-ltsc2019
ARG source
RUN Add-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST' -filter "system.applicationHost/sites/site[@name='Default Web Site']/logFile/customFields" -name "." -value "@{logFieldName='X-Forwarded-For';sourceName='X-FORWARDED-FOR';sourceType='RequestHeader'}"

WORKDIR /inetpub/wwwroot
COPY ${source:-obj/Docker/publish} .

当我运行 docker build 时，出现以下错误

Sending build context to Docker daemon  4.096kB
Step 1/5 : FROM mcr.microsoft.com/dotnet/framework/aspnet:4.8-windowsservercore-ltsc2019

Dockerfile 在没有RUN Add-WebConfigurationProperty. 如果我在没有它的情况下构建它，RUN Add-WebConfigurationProperty我可以运行容器并执行Add-WebConfigurationProperty命令并看到它确实将字段添加到日志文件中。知道为什么它不能通过 Dockerfile 工作。

我也遇到了 Windows Dockerfiles 的一些转义问题，有时我会为我需要的东西拉入一个 powershell 脚本。

在这种情况下，因为我假设您只想添加该字段，您可以使用：

-filter "system.applicationHost/sites/siteDefaults/logFile/customFields"

希望这可以帮助！

谢谢！
