Hi @arun1895, can you try in another distro to ensure it works in any? I'll try to follow up when I can.

Hi @arun1895 , can you try in another distro to ensure it works in any? I'll try to follow up when I can.

Thank you for your reply@Ralph Squillace ,i had tried with distro but facing the same issue, would you kindly help me out how to solve this issue?

below its my docker file

FROM microsoft/dotnet:2.1-aspnetcore-runtime AS base WORKDIR /app EXPOSE 50223 EXPOSE 44349

FROM microsoft/dotnet:2.1-sdk AS build WORKDIR /src COPY "dockertest/dockertest.csproj", "dockertest/" RUN dotnet restore "dockertest/dockertest.csproj" COPY . . WORKDIR "/src/dockertest" RUN dotnet build "dockertest.csproj" -c Release -o /app

FROM build AS publish RUN dotnet publish "dockertest.csproj" -c Release -o /app

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

@arun1895 hmmmm. Is this the example dotnetcore app in the repo, or another one that you are using?

@arun1895 hmmmm. Is this the example dotnetcore app in the repo, or another one that you are using?

the same am using for the testing if it will be run successfully, then we proceed with our build projetcs.

[squillace]

so, example-dotnetcore in this repo has the following, which means your Dockerfile is your own. Correct?

FROM microsoft/dotnet:2.1-sdk AS builder
WORKDIR /app

# caches restore result by copying csproj file separately
COPY *.csproj .
RUN dotnet restore

COPY . .
RUN dotnet publish --output /app/ --configuration Release
RUN sed -n 's:.*<AssemblyName>\(.*\)</AssemblyName>.*:\1:p' *.csproj > __assemblyname
RUN if [ ! -s __assemblyname ]; then filename=$(ls *.csproj); echo ${filename%.*} > __assemblyname; fi

# Stage 2
FROM microsoft/dotnet:2.1-aspnetcore-runtime
WORKDIR /app
COPY --from=builder /app .

ENV PORT 80
EXPOSE 80

ENTRYPOINT dotnet $(cat /app/__assemblyname).dll

this is with Draft v. 0.16

[arun1895]

this is with Draft v. 0.16

Yes we created own file for testing, so that we can run our very own webistes on docker

I strongly suggest you have a look at mapping your dockerfile to be closer to this one, until you figure out why you're copying a directory that doesn't exist -- it almost looks like the docker environment you're running in is broken -- or at least very, very different. The fact that your Dockerfile doesn't work on other distros strongly implies that your dockerfile is wrong, or the docker config.

I can help you with Draft itself, but when you create your own dockerfile, you're going to have to find a way to debug it yourself. :-(

[arun1895]

Could you please share any aspnet core sample dockeer file , and how build it

https://github.com/Azure/draft/issues/901#issuecomment-440662599. this is what Draft creates for the example-dotnetcore getting started application. Start with that.
