S3 Automatic Image Compression

This project provides automatic lossless compression of jpegs when they are added to an s3 bucket. Read this article for a full explanation of how to set-up AWS to get this working.

Installation

The has been been tested on Python 3.4.3 on OS X. It should run on Linux but the mozjpeg installation instructions will differ. OS X ships with Python 2 but you can install multiple versions https://www.python.org/downloads/.

0. Install mozjpeg. For OS X this can be done with:

   brew install mozjpeg
   

1. Set environment variables for AWS.

   export AWS_ACCESS_KEY_ID=<your-aws-access-key>
   export AWS_SECRET_ACCESS_KEY-<your-aws-secret-key>
   

2. Optional: Create Virtual Enviroment for Python 3 (you may need to change the python location depending on your set-up).

   mkvirtualenv --python=/usr/local/bin/python3 s3-image-resize
   

3. Install requirements

   pip install -r requirements.txt
   

4. Run code

   python connect_to_queue.py
   

   When updates are made to s3 they'll automatically be compressed an uploaded again.
