steps.txt

1. create new app in dashboard.heroku.com

2. create Procfile
echo "web: gunicorn <app-name>.wsgi --log-file -1" >  Procfile

3. add settings file for heroku
from .<base-settings-file> import *
import dj_database_url

ALLOWED_HOSTS = ['<name-app>.herokuapp.com', ]
db_from_env = dj_database_url.config(conn_max_age=500)
DATABASES['default'].update(db_from_env)

4. install dj-database-url and whitenoise
pip install gunicorn dj-database-url whitenoise
pip freeze | grep -i dj-database-url >> requirements.txt
pip freeze | grep -i  whitenoise >> requirements.txt

5. check or configure static:
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
STATIC_URL = '/static/'
STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'static'),
)

6. set env var DJANGO_SETTINGS_MODULE in heroku dashboard (tab "Settings")

7. update wsgi.py
import os

from django.core.wsgi import get_wsgi_application
from whitenoise.django import DjangoWhiteNoise

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "<PATH_TO_SETTINGS>")
application = get_wsgi_application()
application = DjangoWhiteNoise(application)

8. set git remote repository
heroku git:remote -a <app-name>

10. set python version
echo "python-3.6.1" > runtime.txt

11. allow to push empty "static" directory to git
mkdir static && touch static/.keep

9. test app on local server
heroku local web
google-chrome http://0.0.0.0:5000

git add .
git commit

12. deploy to heroku
git push heroku master

13. migrate DB

heroku run python manage.py createsuperuser

15. check deployed application
heroku open

16. configure AWS S3 for media files (optional)
pip install django-storages boto
pip freeze | grep -i django-storages >> requirements.txt
pip freeze | grep -i boto >> requirements.txt
add "storages" to INSTALLED_APPS
add to settings
DEFAULT_FILE_STORAGE = 'storages.backends.s3boto.S3BotoStorage'
AWS_STORAGE_BUCKET_NAME = ''
AWS_SECRET_ACCESS_KEY = ''
AWS_ACCESS_KEY_ID = ''
