Deployment on Heroku
====================
.. index:: Heroku
Commands to run
---------------
Run these commands to deploy the project to Heroku:
.. code-block:: bash
heroku create --buildpack https://github.com/heroku/heroku-buildpack-python
heroku addons:create heroku-postgresql:hobby-dev
# On Windows use double quotes for the time zone, e.g.
# heroku pg:backups schedule --at "02:00 America/Los_Angeles" DATABASE_URL
heroku pg:backups schedule --at '02:00 America/Los_Angeles' DATABASE_URL
heroku pg:promote DATABASE_URL
heroku addons:create heroku-redis:hobby-dev
heroku addons:create mailgun:starter
heroku config:set PYTHONHASHSEED=random
heroku config:set WEB_CONCURRENCY=4
heroku config:set DJANGO_DEBUG=False
heroku config:set DJANGO_SETTINGS_MODULE=config.settings.production
heroku config:set DJANGO_SECRET_KEY="$(openssl rand -base64 64)"
# Generating a 32 character-long random string without any of the visually similar characters "IOl01":
heroku config:set DJANGO_ADMIN_URL="$(openssl rand -base64 4096 | tr -dc 'A-HJ-NP-Za-km-z2-9' | head -c 32)/"
# Set this to your Heroku app url, e.g. 'bionic-beaver-28392.herokuapp.com'
heroku config:set DJANGO_ALLOWED_HOSTS=
# Assign with AWS_ACCESS_KEY_ID
heroku config:set DJANGO_AWS_ACCESS_KEY_ID=
# Assign with AWS_SECRET_ACCESS_KEY
heroku config:set DJANGO_AWS_SECRET_ACCESS_KEY=
# Assign with AWS_STORAGE_BUCKET_NAME
heroku config:set DJANGO_AWS_STORAGE_BUCKET_NAME=
git push heroku master
heroku run python manage.py createsuperuser
heroku run python manage.py check --deploy
heroku open

Optional actions
----------------
Celery
++++++
Celery requires a few extra environment variables to be ready operational. Also, the worker is created,
it's in the ``Procfile``, but is turned off by default:
.. code-block:: bash
# Set the broker URL to Redis
heroku config:set CELERY_BROKER_URL=`heroku config:get REDIS_URL`
# Scale dyno to 1 instance
heroku ps:scale worker=1
Sentry
++++++
If you're opted for Sentry error tracking, you can either install it through the `Sentry add-on`_:
.. code-block:: bash
heroku addons:create sentry:f1
Or add the DSN for your account, if you already have one:
.. code-block:: bash
heroku config:set SENTRY_DSN=https://xxxx@sentry.io/12345
.. _Sentry add-on: https://elements.heroku.com/addons/sentry
Gulp & Bootstrap compilation
++++++++++++++++++++++++++++
If you've opted for a custom bootstrap build, you'll most likely need to setup
your app to use `multiple buildpacks`_: one for Python & one for Node.js:
.. code-block:: bash
heroku buildpacks:add --index 1 heroku/nodejs
At time of writing, this should do the trick: during deployment,
the Heroku should run ``npm install`` and then ``npm build``,
which runs Gulp in cookiecutter-django.
If things don't work, please refer to the Heroku docs.

About Heroku & Docker
---------------------
Although Heroku has some sort of `Docker support`_, it's not supported by cookiecutter-django.
We invite you to follow Heroku documentation about it.
