Devops Candidate Take-Home Assessment
The purpose of this assessment is to validate that the candidate can:
- package and ship a web application
- use docker
- understand python dependency management
- understand Python/Django basics
- understand networking basics
- understand Unix/Linux basics
- explain their design/architecture decisions
As a way to determine your ability to produce quality work autonomously and demonstrate a few skills, we would like you to containerize a small web application for us. The web app is a tiny Django app with one model and one view. All it does is count page views. Imagine a junior developer has just built this and wants to deploy it. They have, so far, only used the default sqlite development database and directly installed things with pip.
Your job is to create a Dockerfile for the web application and its dependencies and a Docker Compose file describing a database and a webserver as well as the web application itself.
The web app should talk to a standalone database, preferably Mysql or Postgres, as opposed to the default sqlite local file-based database. The application itself should talk to the standalone database and sit behind a web server. This will require changing the Django settings file so the database can be configured to talk to the standalone database.
You will also need to link all of the containers up in the docker-compose.yml file. We would prefer you use Nginx for the web server, but if you know another technology that would fit better, feel free to use it.
You may use community docker images for the web server and database server, but we would like you to write the Dockerfile for the web application.
Please send us back the project repository with the following:
- Changes to the settings file
- Any files required for building or dependency management
- A Dockerfile for building the web application docker image
- A docker-compose.yml file that can be used to spin up the app/web server/database as a cluster. We should be able to build the cluster by just issuing
- A file explaining any decisions you had to make or challenges you overcame.
We would love to see:
- Project history (We sent you a git repository, so you can commit your work as you see fit)
- Some way to repeatedly test that your cluster is communicating correctly.
