ChowNow: Infrastructure Engineer Coding Challenge

Get the Flask 'Hello World' app up and running on a Vagrant VM using your known best practices as well as the instructions in the guidelines below. You must use Ansible as your provisioner to install and configure everything. When you're done, we should be able to type vagrant up and our app will be running and reachable on http port 80 at http://192.168.33.15.

Guidelines:

• The provisioner should clone a Github-hosted repo into the VM under /etc/chownow/infratest
• The app should route through nginx and gunicorn or uWSGI.
• The app should be running as a non-privileged user
• The app should be automatically restarted if crashes or is killed
• The app should maximize all of the available CPUs (have Vagrant virtualize multiple CPUs and use them)

I have a project that's a few years old, but needs some maintenance. Since I last worked on the project, two major things have happened. First, Elixir -- a declarative layer on top of SQLAlchemy -- has not been maintained. Secondly, SQLAlchemy now has its own declarative layer.

Rather than continue using Elixir, I decided to migrate my data models to use the new SQLAlchemy declarative layer, which interestingly enough appear to be relatively compatible with Elixir's philosophy.

The first thing I did was do a direct mapping in my model columns and update the import statements.

# from Elixir import Entity, Field, DateTime, Unicode, Integer, Boolean, setup_all, create_all, session, metadata
from sqlalchemy import Column, DateTime, String, Integer, ForeignKey, Boolean
from sqlalchemy.ext.declarative import declarative_base
