Running .exe in docker locally

Question

I have a very small .net console application,

 static void Main(string[] args)
        {
            Console.WriteLine("This is testing!");
            Console.ReadLine();
        }

The path structure is like this C:\Kubernetes\src\Sample\bin\Release \debug

My project, dockerfile and sln file are all inside the sample folder

My dockerfile looks like this,

FROM mcr.microsoft.com/windows/servercore:ltsc2016
ADD . /bin/Release
ENTRYPOINT Sample.exe

I build the image successfully using the following command,

docker build . -t samplekube:local

When I try to run the image locally

docker run samplekube:local

I get the following error,

'Sample.exe' is not recognized as an internal or external command,
operable program or batch file.

How do I test an image that contains an.exe in the docker locally?

Thanks

Hi I am not familiar with .net but Execution is complaining about Sample.exe is not found. You're placing the file in /bin/Release directory in the Dockerfile. So having this line would make more sense: ENTRYPOINT /bin/Release/Sample.exe

And also the directory path is containing unix like directory path eventhough the base image is windows server so I think the error must have come from one of those things i mentioned.

I advice you to execute shell on the Entry point to enter the container and find the location of the file
