Docker复制命令失败

Question

我是Docker的新手，同时运行Docker文件**我的Docker文件**

1. 来自Microsoft/DotNet:2.2.0-Preview1-AspNetCore-Runtime作为基础
2. 工作目录/app
3. 来自Microsoft/DotNet:2.2.100-Preview1-SDK AS Build
4. workdir/dineshvisualstudio/autofac-interceptor/autofacmodule/autofac.interface.concactFactory
5. 复制autofac.interface.concatfactory.csproj项目/
6. workdir/autofac-拦截器/project
7. 运行dotnet还原
8. 复制/autofac.interface.concactFactory。
9. 运行dotnet Build-C Release-O/App
10. 从生成为发布
11. 运行dotnet publish-c release-o/app
12. 从基数作为最终值
13. 工作目录/app
14. 复制--from=publish/app.
15. 入口点[“autofac.interface.concatfactory.exe”]

运行Build-T myappfactory时。它的失败。我尝试了许多组合路径在复制命令，但没有运气。

**我正在使用Visual studio 2017并且也安装了Docker工具**这是我的文件夹结构

我正在使用Cmd从我当前的working.csproj文件夹构建docker。

{ 
D:\DineshVisualStudio\Autofac- 
Interceptor\AutofacModule\Autofac.Interface.ConcatFactory>**docker build -t 
autofacinterfaceconcatfactory .**

**after @Mike suggestion .Now I am getting an issue**


{    D:\DineshVisualStudio\Autofac- 
     Interceptor\AutofacModule\Autofac.Interface.ConcatFactory>docker build 
    -t myappfact .
    Step 6/15 : WORKDIR /Autofac-interceptor/project
      Step 7/15 : RUN dotnet restore
     ---> Running in 9e91df3e68a3
    MSBUILD : error MSB1003: Specify a project or solution file. The current 
   working directory does not contain a project or solution file.
   The command 'cmd /S /C dotnet restore' returned a non-zero code: 1

我认为您不需要copy/autofac.interface.concatfactory.csproj中的前导/。源文件是相对于当前工作目录的，您之前已经调用了workdir。
