    CMD ["python", "Hello.py"]

> docker run -v /Scripts:/usr/src/app app
python: can't open file 'Hello.py': [Errno 2] No such file or directory

Answer 1

You are OVERWRITING the directory.

You have first said "Copy the application and source code to /usr/src/app . Then said, "ignore that, overwrite the entire /usr/src/app directory with /Scripts by using -v /Scripts:/usr/src/app .

To fix.

1. Send the volume to a DIFFERENT directory. /mnt is perfect for that.
2. Your docker container only knows about the files IN the container. Since you are sending the volume to /mnt , you must change your C:\\Scripts\\ to /mnt .
