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

Docker 前端之家
前端之家收集整理的这篇文章主要介绍了dotnet build使用dotnet在docker容器中失败：2.1-sdk，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

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.在dotnet build命令期间失败,说它无法加载共享库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：

为什么当文件清楚地出现在文件夹中并且只是成功用于执行网络还原时,它无法找到该文件？

UPDATE
该错误建议设置LD_DEBUG,所以我做了,它产生了这个信息：

最佳答案
当我使用Visual Studio 2017(预览)添加> Docker支持它为microsoft.visualstudio.azure.containers.tools的web项目添加了一个包引用.删除此引用让我超越了错误,我最终能够在此时将应用程序停靠.由于VS的行为的在线文档仅表明它添加了一个Dockerfile,而不是它与项目混淆,因此并没有立即显示这个包已被添加.
