Django tutorial using Docker, Nginx, Gunicorn and PostgreSQL.

This is Django tutorial in steroids, I wanted to go through the tutorial using a configuration that is more close to production.

I am running the django app with gunicorn, using postgres as the database, the django app is behind nginx and everything is running out of Docker containers orchastrated with docker-compose.

Setup

I am running this on a Macbook air running Yosemite with boot2docker.

Running

  1. git clone this repo
  2. boot2docker up
  3. sh rebuild_docker.sh
  4. run migrations in your Django instance: docker-compose run django /bin/sh -c 'cd mysite;python manage.py migrate'
  5. access it in your browser! http://192.168.59.103/ for me, run boot2docker ip to know where it is running.

docker-compose.yml

Compose is a tool for defining and running multi-container applications with Docker. With Compose, you define a multi-container application in a single file, then spin your application up in a single command which does everything that needs to be done to get it running.

https://docs.docker.com/compose/

We have three containers: Nginx, Postgres and a Django App.

  • django

    • Built from ./Dockerfile, running gunicorn to serve our django app.
  • postgres

    • Just the basic image from DockerRegistry.
  • nginx

    • We are building it from nginx/Dockerfile. In our nginx/nginx.conf we are basically proxying django to gunicorn and serving static files which gunicorn doesn't do for us.

rebuild_docker.sh

Created to make life easier:

  1. Build your docker-compose file.
  • docker-compose build
  1. Runs your containers on detached mode.
  • docker-compose up -d
  1. Check if they are all running.
  • docker-compose ps

Running commands inside containers

use docker-compose run CONTAINER_NAME command for example:

  • Testing polls app

    • docker-compose run django /bin/sh -c 'cd mysite;python manage.py test polls'
  • Running ls

    • docker-compose run django /bin/sh -c 'ls'
  • Running Python directly

    • docker-compose run django python

Checking logs

use docker-compose logs CONTAINER_NAME
