A package to assist with running scrapy on heroku. This is accomplished by providing
a custom application configuration at scrapy_heroku.app.application that launches
the scrapyd web service using the PORT environment variable and a multi-process work
queue implemented on a Postgres database specified by the DATABASE_URL environment
variable.
Create a git repo that has a scrapy project at the root (scrapy.cfg should be at the top level). Edit your scrapy.cfg to include the following::
[scrapyd]
application = scrapy_heroku.app.application
[deploy]
url = http://<YOUR_HEROKU_APP_NAME>.herokuapp.com:80/
project = <YOUR_PROJECT_NAME>
username = <A_USER_NAME>
password = <A_PASSWORD>
Add a requirements.txt file that includes scrapy-heroku in it. It is strongly
recommended that you version pin scrapy-heroku as well as the version of scrapy that
your project is developed against (pip freeze > requirements.txt). Finally create a
Procfile that consists of::
web: scrapy server
Make sure you have a postgres database that has been promoted to DATABASE_URL
