I want to pass argument to python file app.py while running its docker image using command :

docker run -d -p 5000:5000 python_app https://github.com/abc/repo

where python_app is image of my application and https://github.com/abc/repo is the argument which I want to pass. But when I run docker image using above command my container exits with error :No such directory or file found

This is my Dockerfile

FROM python:2.7.13
MAINTAINER xyz "[email protected]"
COPY . /app
WORKDIR /app
RUN pip install -r requirements.txt
ENTRYPOINT ["python"]
CMD ["app.py","https://github.com/abc/repo"]

I think my param2 in CMD is treated an argument for docker image rather than argument for python application.

td;lr use ENTRYPOINT ["python", "app.py"] then you can pass parameters to the docker run

see answer here: how to pass command line arguments to a python script running in docker td

python: can't open file 'github.com/abc/config-example': [Errno 2] No such file or directory....I am still getting this error
does the script run when passed that argument. this looks like a python error not docker
it runs perfectly fine when I make it static string instead of passing it as argument
ok, forget docker for a second, run app.py 'github.com/abc/config-example' in the shell. does that run error free?
yes , without docker also it runs perfectly fine, that's why I thought it might be docker issue or something with argument
