Disclaimer: I am pretty green with Docker and gunicorn. I am running a Flask application inside a docker container. I am running the following:

docker run --runtime=nvidia -it my-image:0.1

and in the logs:

[2019-09-18 18:02:21 +0000] [9] [INFO] Booting worker with pid: 9
usage: gunicorn [-h] [--model MODEL] [--cam_id CAM_ID] [--cam_width 
 CAM_WIDTH]
            [--cam_height CAM_HEIGHT] [--scale_factor SCALE_FACTOR]
            [--notxt]
gunicorn: error: unrecognized arguments: -b :8080 main:app

I know this question has been asked multiple times (here, here, and here for example) but none of the answers seemed to help.

Here is the content of my Dockerfile:

FROM gcr.io/deeplearning-platform-release/pytorch-gpu.1-1

RUN apt-get update
ADD . /app
WORKDIR /app

RUN pip install --no-cache-dir -r requirements.txt

ENTRYPOINT ["gunicorn", "-b", ":8080", "main:app"]

and main.py looks like this:

from flask import Flask, request
import model

app = Flask(__name__)

@app.route('/getduration', methods=['POST'])
def get_duration():
    try:
        video_url = request.args.get('video')
    except:
        video_url = None   
    try:
        duration = model.run(video_url)
        result = str(duration)
        return result, 200
    except Exception as e:
        error = f"There was an error: {e}"
        return error, 500

if __name__ == '__main__':
    app.run(host='127.0.0.1', port=8080, debug=True)

I've tried creating a wsgi.py file containing:

from main import app

if __name__=="__main__":
    app.run()

then changed my Dockerfile entrypoint:

ENTRYPOINT ["gunicorn", "-b", ":8080", "wsgi:app"]

What am I missing?

Note that if I just run python main.py inside my container, my flask app works fine. When I changed my Dockerfile entrypoint to CMD ["python", "main.py"], the server runs, but I don't get any response when I make requests.
