- 3. Why Heroku? ● ● ● ● Focus on developer productivity 100% free plan includes hosting & db No need to think about servers Easily scales
- 4. Prerequisites Familiarity with: ● command line ● git
- 5. Prerequisites Install: ● pip http://www.pip-installer.org ● Postgres pip install psycopg2 http://initd.org/psycopg/
- 6. Prerequisites Install: ● Virtualenv pip install virtualenv
- 7. Getting Started 1. Sign up for a Heroku account at Heroku.com 2. Install Heroku Toolbelt: https://toolbelt.heroku.com 3. Log in via command line
- 8. Create a Django app locally $ $ $ $ $ mkdir mysite && cd mysite virtualenv venv --distribute source venv/bin/activate pip install django-toolbelt django-admin.py startproject mysite .
- 9. Create a Procfile Create a Procfile in your root project directory: # Procfile web: gunicorn hellodjango.wsgi
- 10. Create requirements.txt $ pip freeze > requirements.txt Note: If you do this out of order, you’ll need to manually create requirements.txt
- 11. Modify settings.py import dj_database_url DATABASES['default'] = dj_database_url.config() SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https') 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'), )
- 12. Modify wsgi.py from django.core.wsgi import get_wsgi_application from dj_static import Cling application = Cling(get_wsgi_application())
- 13. Store your app in git First create a .gitignore file; add: venv *.pyc staticfiles
- 14. Store your app in git Initialize a new git repository $ git init Add the new files $ git add . Commit your files $ git commit -m "initial commit"
- 15. Push your code to Heroku Create a new app on Heroku $ heroku create Deploy your code to Heroku $ git push heroku master
- 16. Start your app Each Heroku app comes with 1 free dyno. Start a Heroku dyno $ heroku ps:scale web=1 Scaling dynos... done, now running web at 1:1X. Terminology: Dynos are isolated, virtualized Unix containers, that provide the environment required to run an application.
- 17. Visit your app $ heroku open
- 18. Visit your app Congrats! You’ve set up a live Djangopowered application via Heroku.
