I am new to Docker , while running the Docker file ** My Docker file **

  1. FROM microsoft/dotnet:2.2.0-preview1-aspnetcore-runtime AS base
  2. WORKDIR /app
  3. FROM microsoft/dotnet:2.2.100-preview1-sdk AS build
  4. WORKDIR /DineshVisualStudio/Autofac-interceptor/AutofacModule/Autofac.interface.ConcactFactory
  5. COPY Autofac.Interface.ConcatFactory.csproj project/
  6. WORKDIR /Autofac-interceptor/project
  7. RUN dotnet restore
  8. COPY /Autofac.interface.Concactfactory .
  9. RUN dotnet build -c Release -o /app
  10. FROM build AS publish
  11. RUN dotnet publish -c Release -o /app
  12. FROM base AS final
  13. WORKDIR /app
  14. COPY --from=publish /app .
  15. ENTRYPOINT ["Autofac.Interface.ConcatFactory.exe"]

When running the build -t myappfactory . its failing . I tried many combination for the path in COPY command but no luck.

** I am using Visual studio 2017 and had installed Docker Tools too ** This is my folder structure

My folder structure with the code having docker file

docker build -t autofacinterface . . I am getting and Error everytime saying failed to create file . System cannot find the file specified.

I am using Cmd to build the docker from my current working .csproj folder.

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

I don't think you need the leading / in COPY /Autofac.Interface.ConcatFactory.csproj. The source file(s) are relative to current working directory, and you've already called WORKDIR previously.

Step 5/15 : COPY COPY

Do you have the word COPY twice in a row in your Dockerfile?

The command "COPY /Autofac.Interface.ConcatFactory.csproj project/" failed. I recommend you read more about the command COPY here. Use the command "COPY . ." if you run docker build from the folder "D:\DineshVisualStudio\Autofac- Interceptor\AutofacModule\Autofac.Interface.ConcatFactory".
