|
Script
|
|
------
|
|
|
|
Run these commands to deploy the project to Heroku:
|
|
|

|
|
|
heroku create --buildpack heroku/python
|
|
|
|
# Note: this is not a free plan

# 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

Notes
|
|
-----
|
|
|
|
Email Service
|
|
+++++++++++++
|
|
|
|
The script above assumes that you've chose Mailgun as email service. If you want to use another one, check the `documentation for django-anymail <https://anymail.readthedocs.io>`_ to know which environment variables to set. Heroku provides other `add-ons for emails <https://elements.heroku.com/addons#email-sms>`_ (e.g. Sendgrid) which can be configured with a similar one line command.
|
|
|
|
.. warning::
|
|
|
|
.. include:: ../includes/mailgun.rst
|
|
|
|
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.
|
|
|
|
.. _Docker support: https://devcenter.heroku.com/articles/build-docker-images-heroku-yml
|
|
|
|
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
|
|
|
|
# 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 or Webpack
|
|
+++++++++++++++
|
|
|
|
If you've opted for Gulp or Webpack as frontend pipeline, 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 run the SASS compilation & JS bundling.
|
|
|
|
If things don't work, please refer to the Heroku docs.
