dotnet build使用dotnet在docker容器中失败：2.1-sdk

时间：2018-05-21 14:48:14

标签： docker asp.net-core-2.0

我正在尝试将docker支持添加到现有的ASP.NET Core 2.1 Web应用程序中。它在dotnet build命令期间失败，表示无法加载共享库kernel32.dll和libkernel32.dll。我有以下Dockerfile 

FROM microsoft/dotnet:2.1-aspnetcore-runtime AS base
WORKDIR /app
EXPOSE 80

FROM microsoft/dotnet:2.1-sdk AS build
WORKDIR /src
COPY . .
RUN ls -la
WORKDIR /src/WebRazorPages
RUN ls -la
RUN dotnet restore -nowarn:msb3202,nu1503
RUN dotnet build --no-restore -c Release -o /app

FROM build AS publish
RUN dotnet publish --no-restore -c Release -o /app

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "WebRazorPages.dll"]

它运行到dotnet构建步骤没有错误，但随后在找到共享文件作为目标文件构建过程的一部分时失败。完整输出如下所示：

为什么文件清楚地显示在文件夹中并且只是成功用于执行dotnet restore时无法找到该文件？

更新 该错误建议设置LD_DEBUG，所以我做了，它产生了这个信息：
