Container exists imemdiately with an error #423

Guys , trying to create an image for very simple asp.net mvc core app . however container exits immediately with this error . Did you mean to run dotnet SDK commands? Please install dotnet SDK from: http://go.microsoft.com/fwlink/?LinkID=798306&clcid=0x409 Docker file: FROM microsoft/aspnetcore:1.1.1

COPY dist /app

WORKDIR /app

EXPOSE 80/tcp

ENTRYPOINT [“dotnet”, “ExampleApp.dll”]

this mvc project is built using .net core 1.1 . i checked in csproj properties dist folders exists and there is a dll with this name exampleapp.dll . its in lower case unlike my docker file . i tried changing case in docker file to match with exactly dll name case . did not help docker image creation messages are below -

All files and directories added to build context will have ‘-rwxr-xr-x’ permissions. It is recommended to double check and reset permissions for sensitive files and directories.

ofcourse if i run application from visual studio it compiles and works fine .

any input why container exits out imemdiatley? thanks siddharth

It exits immediately because it can't find ExampleApp.dll. Double check your file casing. You can debug this better by chaning the entrypoint to a shell and try running dotnet ExampleApp.dll in interactive mode. docker run --rm -it --entrypoint sh my-image
