docker - 尝试 Dockerize ASP.NET Core 5.0 应用程序时出现错误 NU1202

Question

我是 Docker 新手，我正在尝试使用以下 Dockerfile 对 ASP.NET Core 5.0 应用程序进行 dockerize

ENV ASPNETCORE_Environment=Production
ENV ASPNETCORE_URLS http://+:5000

WORKDIR /server
VOLUME ./wwwroot/Repository
COPY . ./

RUN dotnet publish -c Release -o publish

EXPOSE 5000/tcp

ENTRYPOINT ["dotnet","publish/Project.dll"]

执行复制时不断收到此错误...

 => [3/4] COPY . ./                                                                                                           0.7s
