AdsNative: Devops Coding Challenge

Get this simple Flask app up and running on a Vagrant VM using your known best devops 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 and http://devops.adsnative.com

Guidelines:

The provisioner should clone this github repo into the VM under /webapps/adsnative
You should be able to find what system packages are needed by looking through the app
You should not need to change the app code in any way
The app should be running as a non-privileged user
The app should be automatically restarted if crashes or is killed

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

Clarify and agree on the scope of the system

User cases (description of sequences of events that, taken together, lead to a system doing something useful)
- Who is going to use it?
- How are they going to use it?

	# import config.
	# You can change the default config with `make cnf="config_special.env" build`
	cnf ?= config.env
	include $(cnf)
	export $(shell sed 's/=.*//' $(cnf))

	# import deploy config
	# You can change the default deploy config with `make cnf="deploy_special.env" release`
	dpl ?= deploy.env
	include $(dpl)

	# Make sure to:
	# 1) Name this file `backup.sh` and place it in /home/ubuntu
	# 2) Run sudo apt-get install awscli to install the AWSCLI
	# 3) Run aws configure (enter s3-authorized IAM user and specify region)
	# 4) Fill in DB host + name
	# 5) Create S3 bucket for the backups and fill it in below (set a lifecycle rule to expire files older than X days in the bucket)
	# 6) Run chmod +x backup.sh
	# 7) Test it out via ./backup.sh
