Thumbor Heroku
Introduction
This project is a Heroku configuration in order to use Thumbor on Heroku. It is configured for very specific needs,
which include the availability of the smart mode (and thus OpenCV), you should fork it in order for it to match your
needs.
Configuration
Detectors
In order for the smart mode to be useful, the DETECTORS are set. This requires OpenCV to be available to Python.
Storages
In the configuration, picture files come from a S3 file storage, wich are as easy to reach that any Heroku addon, so there is no need for a file storage.
The generated output are supposedly kept by a reverse proxy put in front of the Thumbor.
However, what can be CPU-heavy is the run of detectors. In this regard, the output of detectors is kept in cache. Here we use a RedisToGo Heroku addon, which can be interchanged with any other one. Memcache addons are however not usable, since they require authentication, which is not supported by Thumbor's storages.
Security Key
The unsafe mode is forbidden, and you need to set a security key. You can do this by setting the
THUMBOR_SECURITY_KEY Heroku environment variable.
Deployment
This project comes along with the jetpack buildpack. The jetpack.sh
configuration file is quite straightforward.
It uses a pre-pack which embeds Python and OpenCV, which are the two dependencies required for Thumbor to run correctly.
License
This chunk of configuration is available under the terms of the WTFPL. See the attached COPYING file.
