Container exists imemdiately with an error


(Kharesiddharth) #1

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 -

C:\ExampleApp>docker build . -t apress/exampleapp -f dockerfile
