I'm running into trouble with the following steps:

1. Create a simple C# .net 6 console app with the Hello World boilerplate, and publish the portable binaries locally.
2. Create a docker container based on mcr.microsoft.com/dotnet/sdk:6.0
3. Copy the publish results to the container in a consoleapp directory.
4. Open an interactive session to the container
5. Execute /consoleapp/ConsoleApp1.exe

No error, but no result. Here's the (only) code in the app:

Console.WriteLine("Hello, World!");

I'm expecting to see:

Hello, World!

I feel like I'm missing something incredibly simple...any help would be appreciated.

CodePudding user response：

The .exe file is only for Windows. In the container (running on Linux) you start your app with

dotnet ConsoleApp1.dll

In this case your Dockerfile would look like this:

FROM mcr.microsoft.com/dotnet/runtime:6.0

WORKDIR /app
COPY bin/Release/net6.0/publish/* .

CMD ["dotnet", "ConsoleApp1.dll"]
