Question

我创建了默认的VS2017 webAPI项目，并为Linux提供了Docker支持。当我尝试构建映像时，遇到诸如“无法找到... / docker-buildxxxx /”之类的问题，为解决该问题，我将dockerfile向上移动了一层，其中* .sln和.dockerignore文件在其中。

我已经成功构建并运行了该映像，但是我没有运气向容器中提出一些请求。我在所有可能的组合中都使用-p host_port：container_port，但这没用。

仅供参考：如果没有docker，它可以正常工作。（dotnet test.dll）

您能提供一些我需要研究的地方吗？或者您能提供确切的解决方案？

Answer 1

那是我一生中最艰难的两个夜晚，但我找到了解决办法。

问题是由Visual Studio引起的，它生成了错误的dockerfile。

固定的dockerfile

FROM microsoft/dotnet:2.1-sdk AS build
WORKDIR /app

# copy csproj and restore as distinct layers
COPY *.sln .
COPY test/*.csproj ./test/
RUN dotnet restore

# copy everything else and build app
COPY test/. ./test/
WORKDIR /app/test
RUN dotnet publish -c Release -o out


FROM microsoft/dotnet:2.1-aspnetcore-runtime AS runtime
WORKDIR /app
COPY --from=build /app/test/out ./
ENTRYPOINT ["dotnet", "test.dll"]

无法将请求发送到由Docker托管的.net核心应用
