Docker 构建错误 - NuGet.targets：错误：对路径的访问被拒绝

Question

我有一个多阶段构建的 Dockerfile（大多数文件是由 VS 生成的）。当我在 Windows 10 机器上通过 Docker 构建我的应用程序时，一切正常。

当我尝试在Windows 2019 Standard服务器上构建时，出现此错误：

    Step 13/20 : WORKDIR "/src/Dining.Api"
     ---> Using cache

当我在Windows 10机器上构建时，这里是 docker build 中同一步骤的输出：

我在我的机器和 Windows Server 上运行 docker 版本 19.03.1。这是 docker 文件：

FROM microsoft/dotnet:2.2-aspnetcore-runtime AS base
WORKDIR /app
EXPOSE 80

FROM microsoft/dotnet:2.2-sdk AS build
WORKDIR /src
COPY ["Dining.Api/Dining.Api.csproj", "Dining.Api/"]
COPY ["Dining.Domain/Dining.Domain.csproj", "Dining.Domain/"]
COPY ["Dining.DataAccess/Dining.DataAccess.csproj", "Dining.DataAccess/"]
COPY ["Dining.Service/Dining.Service.csproj", "Dining.Service/"]
COPY ["NuGet.Config", "./"]
RUN dotnet restore "Dining.Api/Dining.Api.csproj"
COPY . .
WORKDIR "/src/Dining.Api"
RUN dotnet build "Dining.Api.csproj" -c Release -o /app

FROM build AS publish
RUN dotnet publish "Dining.Api.csproj" -c Release -o /app

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "Dining.Api.dll", "--server.urls", "http://*:80"]

我研究并发现了这个：https : //github.com/NuGet/Home/issues/7836 它提供了很多关于错误的细节，但并没有真正提供解决方案。我尝试使用 .dockerignore 来排除 **/obj/ 目录中的复制文件，但问题仍然存在。有没有人遇到过这个问题并提出解决方案/变通方法？

我设法通过添加解决了类似的问题

USER Administrator

到 docker 文件，如下所示：DotNet 6 无法在 Windows 容器中运行：权限被拒绝
