CLI Application with docker

I building a CLI python application that takes a CSV file as argument input and various options

Example: rexona [-h] [-v | -q] [-o] filepath

My question is how to dockerize it in a way that when I run my docker file I can run the above command and pass in the specified arguments?

My current docker file

FROM python:3
WORKDIR .

COPY . .

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

Should I also install an os image such as ubuntu, so that I can run cmd commands or is there a way to that in docker?

Apologies, I'm still new to docker. Thanks

I also run into similar senario i solved it using Entry point

ENTRYPOINT [ "python", "script.py" ]

run script

docker run arg1 arg2 arg3...

And then in Python Program

import sys
print(sys.argv)

You need to add entry point for eg:

# Base image of the docker container
FROM python:3


# Copy the contents of the repo into the /app folder inside the container
COPY . /app
# Update the current working directory to the /app folder
WORKDIR /app

# Add your CLI's installation setups here using the RUN command
# If you have any pip requirements you can do that here
# RUN pip install --user -r requirements.txt

# Provdide a path to your cli apps executable
ENTRYPOINT [ "python", "script.py" ]
