Deployment

Gunicorn

Installing gunicorn on linux with pip3 install gunicorn.

Using it with: gunicorn -w 4 -b 0.0.0.0:4000 app:application
This line means 4 threads on public domain with port 4000 using the application in app.py.

Docker

A basic docker file can looks like this:

FROM python:3.6.4-alpine3.7
WORKDIR /app
ADD . /app
RUN pip install -r requirements.txt
CMD ["gunicorn", "-w 4", "-b 0.0.0.0:4000", "app:application"]
