You can probably copy only Python files and requirements.txt. We don't need anything else in the image to run the app.

You can use .dockerignore file to acomplish that. Check this documentation and my example.

This file will tell ADD/COPY to ignore some files you don't want to see in the image.

I just understood that README.md has no documentation about running the bot in Docker yet.

I think it's a good idea to fix that.
