I have a simple docker file which I am using to containerize my python app. The app actually takes file paths as command line arguments. It is my first time using Docker and I am wondering how I can achieve this:
FROM python:3.6-slim COPY . /app WORKDIR /app RUN apt-get update && apt-get -y install gcc g++ # Install numpy, pandas, scipy and scikit RUN pip install --upgrade pip RUN pip --no-cache-dir install -r requirements.txt RUN python setup.py install ENTRYPOINT python -m myapp.testapp
This builds the image completely fine. I can also run it using:
docker run -ti myimg
However, I cannot pass any command line arguments to it. For example, my app prints some help options with the -h option.
However, running docker as:
docker run -ti myimg -h
does not do anything. So, the command line option are not being passed.
Additionally, I was wondering what the best way to actually pass file handles from the host computer to docker.
So, for example, the application takes path to a file as an input and the file would usually reside on the host computer. Is there a way for my containerized app to be able to access that?
