Usage

Build your own image

FROM moppermonster/alpine-python-flask

COPY app.py /app.py

CMD ["/usr/bin/supervisord"]

Mount your own files

An alternative to building your own container is mounting files over existing locations in the container.

Interesting files and their locations (in the container):

File	Description
/app.py	Main app, an example is provided with this repository
/static/	Static directory, by default NGINX is configured to deliver static content from this location
/etc/nginx/nginx.conf	NGINX config file
/etc/nginx/conf.d/flask-site-nginx.conf	NGINX config extension, static can be configured from here
/etc/uwsgi/uwsgi.ini	UWSGI config file
/etc/supervisord.conf	Supervisord config file

docker-compose

Mounting files is considerably easier using docker-compose. This repository contains some examples.
