Sphinx Heroku Buildpack

A Heroku buildpack to generate launch a sphinx documentation based on the same repository.

For more information read about Heroku Buildpacks

Setting up Sphinx Heroku Buildpack

Setting up documentation with graphviz.

  • Create heroku app to host sphinx documentation.
heroku create myapp-docs

The order of buildpacks on your application is important!

  • First setup heroku-buildpack-graphviz
heroku buildpacks:set https://github.com/weibeld/heroku-buildpack-graphviz.git
  • Setup sphinx-heroku-buildpack
heroku buildpacks:set https://github.com/Thermondo/sphinx-heroku-buildpack.git
  • Finally setup heroku's official python buildpack
heroku buildpacks:set heroku/python

When listing the buildpacks on our application, we get this result:

heroku buildpacks --app myapp-docs
=== myapp-docs Buildpack URLs
1. https://github.com/weibeld/heroku-buildpack-graphviz.git     # If you need graphiz
2. https://github.com/Thermondo/sphinx-heroku-buildpack.git
3. heroku/python


With Heroku auto deploy configured it reduces deployment time by serving sphinx documentation on a separate Heroku app but still using the same source code for your application. And allows to host private documentation.

Use Case

When using Heroku, Github and Travis:

git push {remotename} master

Your application myapp will be tested by travis and deployed regularly to Heroku, while sphinx documentation will be build and served on myapp-docs separately.

Custom wsgi.py file

You can have a custom wsgi.py file to enable oauth2 authentication and use SSL.

  • Create a wsgi.py file in your docs folder
touch docs/wsgi.py
  • Customize the wsgi.py file to authenticate user login using wsgi-oauth2 and SSL.
import os

import requests
import static
from wsgi_sslify import sslify
from wsgioauth2 import Service

class GoogleService(Service):
    def __init__(self, allowed_domains=None):

        if isinstance(allowed_domains, str):
            allowed_domains = allowed_domains.split(',')
        self.allowed_domains = allowed_domains

    def is_user_allowed(self, access_token):
        response = requests.get(
            params={'access_token': access_token['access_token']},

        res = response.json()
        email = res['email']
        verified = res['verified_email']
        return any(
            for allowed_domain in self.allowed_domains
        ) and verified

key = os.environ.get('GOOGLE_OAUTH2_KEY')
secret = os.environ.get('GOOGLE_OAUTH2_SECRET')

google = GoogleService(allowed_domains=os.environ.get('GOOGLE_ALLOWED_DOMAINS'))

client = google.make_client(client_id=key, client_secret=secret, scope="email")

application = static.Cling('/app/docs/_build/html')
application = client.wsgi_middleware(application, secret=secret.encode('utf-8'), path='/oauth2/')
application = sslify(application, proxy_header='X-Forwarded-Proto')

Custom post_compile file

  • Create a post_compile file in your docs folder
touch docs/post_compile
  • Customize your post_compile
Your custom commands

pip install -r ${BUILD_DIR}/docs/requirements.txt

# Build Sphinx documentation
(cd ${BUILD_DIR}/docs && make apidoc html)
