Git, S3 and MaxCDN Python deploy script. The script gets the changed file between the two latest Git commits, uploads the changed files to S3 and then purges the paths from MaxCDN using the API.

s3-maxcdn-deploy.py

#!/usr/bin/env python

#install the follow first:

#sudo easy_install pip

#sudo pip install -U boto

#sudo pip install configparser

#sudo pip install gitpython

#sudo pip install requests

#sudo pip install certifi

#sudo pip install netdnarws

#then setup the config files in your root user directory. these files store your api information for s3 and maxcdn

#.aws file should look like this: https://gist.github.com/4596753

#.maxcdn file should look like this: https://gist.github.com/4596743
