docker-flask-scipy

A small image with fully working SciPy and an infrastructure sufficient for a simple web service.

Includes:

• runit
• Gunicorn (gevent/greenlet)
• Flask
• NumPy and SciPy

Usage

Add application code and a runit script starting Gunicorn.

A basic derived Dockerfile could look as follows:

FROM wrwrwr/flask-scipy

COPY requirements.txt /app/requirements.txt
RUN pip install -r /app/requirements.txt
COPY . /app
COPY run.sh /etc/service/app/run

The run.sh script needs to start the Gunicorn server:

#!/usr/bin/env bash

cd /app
gunicorn --config /etc/gunicorn/config.py app:app

Possible improvements

• Strip the base (Debian) image from systemd, docs etc.
• Or research NumPy on Alpine test errors and reconsider changing the base.
• Compile ATLAS during build or allow compiling it for a chosen architecture.
