Dockerizing your flask application

First we run our flask app into a apache server, so we need to configure apache server. A full tutorial can be checked here

wsgi file

#!/usr/bin/python
import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/")

from src.run import app as application

App python

import sys
sys.path.insert(0,"/var/www/")

from app.application import ExampleApi

from config import Configuration

cfg = Configuration(debug=False)
app = ExampleApi(cfg)
if __name__ == "__main__":
    app.run(host=cfg.host,port=cfg.port,debug=cfg.debug)
