A barebones Drupal 8 installation that falls somewhere between the core minimal and standard installation profiles, which can easily be deployed to Heroku.

$ git clone [email protected]:mscharley/drupal-heroku-demo
$ cd drupal-heroku-demo
$ composer install

Install the Heroku Toolbelt.

$ heroku create
$ heroku addons:create heroku-postgresql:hobby-dev
$ git push heroku master
$ heroku open core/install.php

You can also use a SQLite database if you wish for testing purposes but be aware that this database won't last through a Heroku dyno restart which notably happens whenever you push code to Heroku as well as roughly every 24 hours.

For more information about the installation profile, see the Drupal project:
