Docker: applications work fine with docker-layout, but how to run it through Visual Studio and debug it?

I have several projects, and they should work in separate containers, and I have a separate library, which also needs to be built. I found the following article on how to do this. I will show the docker file for only one project, because they are pretty much the same:

FROM microsoft/aspnetcore:2.0 AS base
WORKDIR /app
EXPOSE 80

FROM microsoft/aspnetcore-build:2.0 AS builder
WORKDIR /src
COPY *.sln ./
COPY Web/Web.csproj Web/
RUN dotnet restore
COPY . .
WORKDIR /src/Web
RUN dotnet build -c Debug -o /app

FROM builder AS publish
RUN dotnet publish -c Debug -o /app

FROM base AS production
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "Web.dll"]

So, as you can see, a multi-stage building is used. if i use docker-compose upthen everything works fine. Then I try to run it through Visual Studio, I see all the steps in the Outputwindow, but in the end I get the following error:

CoreCLR. , .NET Core. , .NET Core. '[13] dotnet' 145 (0x91). '' 145 (0x91).

? github repo.

PS. Tarun, , VS

FROM microsoft/aspnetcore:2.0
ARG source
WORKDIR /app
EXPOSE 80
COPY ${source:-obj/Docker/publish} .
ENTRYPOINT ["dotnet", "Web.dll"]

  1. Paths in docker-compose and Dockerfile You should also be aware that changing the context in docker-compose.yml may require making changes to the Dockerfile project. Paths in the Dockerfile are contextual, not Dockerfile. Changing the context in docker-compose.yml may violate these relative paths.
