处理“HTTP请求超时。 退出“。为Docker构build一个大型的aspnet项目

我有一个使用MVC6的多项目aspnet解决scheme

解决scheme文件分为三个项目

sln +---- Model +---- API +---- Web 

Docker文件与SLN文件位于同一文件夹中，并具有以下内容

  FROM microsoft/aspnet COPY . /app WORKDIR /app/Web RUN ["dnu", "restore"] EXPOSE 5004 ENTRYPOINT ["dnx", ".", "kestrel" ] 

当我运行docker build -t myapp . 从powershell命令行是build立过程开始超时。

我尝试过寻找这方面的答案，然后做一些事情，比如重新启动Docker机器或者删除并重build（以kitematic），但即使这些解决schemeDID工作（他们不这样做），解决scheme似乎也不太理想。

请注意，我也试图从超时的同一台机器上查看正在超时的URL，并且他们在Windows中工作。

我认为这可能意味着virtualbox docker机器可能会超时，使其可以打开的连接数量达到饱和

docker镜像是Docker工具箱附带的默认boot2docker linux实例。

它在Windows 10上运行。

另外，如果我在一个新的aspnet项目上运行相同的设置和命令（使用yo aspnet生成器创build），docker确实成功地构build了项目。

在搞清楚如何构builddocker图像的任何帮助将非常赞赏。
