如何使用代理在 docker 容器中恢复 nuget 包？

Question

我正在尝试使用这个简单的 dockerfile 在 linux docker 容器中恢复 nuget 包：

FROM mcr.microsoft.com/dotnet/sdk:5.0 AS build-env
WORKDIR /app

# Copy csproj and restore as distinct layers
COPY *.csproj ./
RUN dotnet restore

使用 Windows 上的命令提示符使用此命令：

docker build --build-arg HTTP_PROXY=http://172.1.0.15:8080 --build-arg HTTPS_PROXY=http://172.1.0.15:8080 --no-cache -t test -f Dockerfile .

导致此错误：

我错过了什么？

这个问题是由我们的代理引起的。我们的基础架构团队必须明确允许 api.nuget.org URL。 错误消息似乎具有误导性。
