How to deploy a Django app on heroku in just 5 minutes

I wrote the article by referring to the official document below. https://devcenter.heroku.com/articles/getting-started-with-django#declare-process-types-with-procfile

Work environment

Prerequisites

  1. Have a heroku account
  2. heroku toolbelt is installed
  3. virtualenv is installed

Introducing PostgreSQL

Installation

$ brew install postgresql

Pass the path (~ / .bash_profile)

export PATH=/usr/local/Cellar/postgresql/9.4.1/bin:"$PATH"

Reboot the terminal

Build a Django environment

** Create and move application management directory **

$ mkdir hellodjango && cd hellodjango

** Build a virtual environment with venv and start it **

$ virtualenv venv
$ source venv/bin/activate

** Download the complete Django-related library **

$ pip install django-toolbelt

** Django project creation **

$ django-admin.py startproject hellodjango .

** Create a Procfile and describe the following contents **

web: gunicorn hellodjango.wsgi --log-file -

** Start local server **

$ foreman start
21:21:26 web.1  | started with pid 5513
21:21:26 web.1  | [2015-05-10 21:21:26 +0900] [5513] [INFO] Starting gunicorn 19.3.0
21:21:26 web.1  | [2015-05-10 21:21:26 +0900] [5513] [INFO] Listening at: http://0.0.0.0:5000 (5513)
21:21:26 web.1  | [2015-05-10 21:21:26 +0900] [5513] [INFO] Using worker: sync
21:21:26 web.1  | [2015-05-10 21:21:26 +0900] [5516] [INFO] Booting worker with pid: 5516

OK if you can access at http://0.0.0.0:5000

Create requirements.txt file representing pip dependencies

$ pip freeze > requirements.txt

Django settings

** Add the following content to the end of settings.py **

# Parse database configuration from $DATABASE_URL
import dj_database_url
DATABASES['default'] =  dj_database_url.config()

# Honor the 'X-Forwarded-Proto' header for request.is_secure()
SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')

# Allow all host headers
ALLOWED_HOSTS = ['*']

# Static asset configuration
import os
BASE_DIR = os.path.dirname(os.path.abspath(__file__))
STATIC_ROOT = 'staticfiles'
STATIC_URL = '/static/'

STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'static'),
)

** Rewrite wsgi.py with the following contents **

import os
from django.core.wsgi import get_wsgi_application
from dj_static import Cling

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "hellodjango.settings")

application = Cling(get_wsgi_application())

git version control

** Create a .gitignore file and add the following contents **

venv
*.pyc
staticfiles

** Add to repository **

$ git init
$ git add .
$ git commit -m "my django app"

Deploy to heroku

** Create repository on heroku **

$ heroku create

** Deploy application to heroku **

$ git push heroku master

** Set the number of dyno **

$ heroku ps:scale web=1

** Check from browser **

$ heroku open

OK if the following screen appears!
