I have create default VS2017 webAPI project with docker support for Linux.
When i had try to build image I met problem like "unable to find .../docker-buildxxxx/" , to solve it i moved dockerfile on one level up, where is *.sln and .dockerignore file are.

I had successfully build and run that image, but i have no luck to take some request into container. I use -p host_port:container_port in all possible combinations, but it is useless.

FYI: without docker it works fine. (dotnet test.dll)

Can you provide some point where i have to research or can you provide exact solution ?

DOCKERFILE

FROM microsoft/dotnet:2.1-aspnetcore-runtime AS base

WORKDIR /app

EXPOSE 80



FROM microsoft/dotnet:2.1-sdk AS build

WORKDIR /src

COPY ["test/test.csproj", "test/"]

RUN dotnet restore "test/test.csproj"

COPY . .

WORKDIR "/src/test"

RUN dotnet build "test.csproj" -c Release -o /app



FROM build AS publish

RUN dotnet publish "test.csproj" -c Release -o /app



FROM base AS final

WORKDIR /app

COPY --from=publish /app .

ENTRYPOINT ["dotnet", "test.dll"]

It was the two hardest nights in my life, but i get a solution.

Problem was caused by Visual studio, it generate wrong dockerfile.

Fixed dockerfile

FROM microsoft/dotnet:2.1-sdk AS build

WORKDIR /app



# copy csproj and restore as distinct layers

COPY *.sln .

COPY test/*.csproj ./test/

RUN dotnet restore



# copy everything else and build app

COPY test/. ./test/

WORKDIR /app/test

RUN dotnet publish -c Release -o out





FROM microsoft/dotnet:2.1-aspnetcore-runtime AS runtime

WORKDIR /app

COPY --from=build /app/test/out ./

ENTRYPOINT ["dotnet", "test.dll"]
