Steps to set up a Django+PostgreSQL app using Dokku on Python 3.5.2

1. Verify needed files & settings

   #PROJ_ROOT/Procfile
   web: gunicorn <myproj>.wsgi
   
   #PROJ_ROOT/requirements.txt
   dj-database-url==0.4.1
   Django==1.10.3
   gunicorn==19.6.0
   psycopg2==2.6.2
   whitenoise==3.2.2
   
   #PROJ_ROOT/runtime.txt
   python-3.5.2
   
   #PROJ_ROOT/<myproj>/settings.py
   INSTALLED_APPS = [
       ...
       'gunicorn',
       ...
   ]
   
   MIDDLWARE = [
       ...
       'whitenoise.middleware.WhiteNoiseMiddlware',
       ...
   ]
   
   DATABASES = {'default': dj_database_url.config(), }
   

2. Install PostgreSQL plugin, create database container

   sudo dokku plugin:install https://github.com/dokku/dokku-postgres.git postgres
   dokku postgres:create <myproj>
   

3. Create web application & link the database container

   dokku apps:create <myproj>
   dokku postgres:link <myproj> <myproj>
   

4. Push our application

   git remote:add dokku dokku@<mydomain.com>:<myproj>
   git push dokku master
   

5. HTTPS via Let's Encrypt

   sudo dokku plugin:install https://github.com/dokku/dokku-letsencrypt.git
   dokku letsencrypt <myproj>
   

6. Enjoy!
