http://www.likecs.com/show-57645.html 你看下这个帖子里面这段描述，然后检查下dockerfile文件的位置对不对：
“添加docker支持后会自动生成dockerfile文件，这里有一个坑，在COPY ["myWebApp/myWebApp.csproj", "myWebApp/"]行中需要注意是myWebApp/myWebApp.csproj，是myWebApp目录下的myWebApp.csproj工程文件，所以需要把创建好的dockerfile拷贝到工程文件目录下。”
默认生成文件是在 E:\myWebApp\myWebApp 目录
吧文件拷贝到 E:\myWebApp 目录即可
PS E:\myWebApp> docker build -t aspnetdemo .

项目如果打了txt文件日志 在哪里可以看到对应的文件呢
@conan_lin: 容器是个隔离的环境，内部也有一套文件路径，先找到运行项目的容器，进入容器之后，去找txt文件的位置，比如项目里存的日志路径是/home/log，那进入容器以后，就在这个文件夹下面找日志。一般运行容器的时候做一下持久化比较好，通过-v命令把容器的日志目录挂载到宿主机的某个文件夹上，这样找日志的时候就不需要进入容器内部，而是直接在宿主机的文件夹里看。
@默卿: 感谢
系统找不到指定的路径。
