My initial draft of the cf_pyrax.py script used in my automation deleted all the contents of a Cloud Files container, and then re-uploaded this content. This process was inefficient and also caused issues loading the site while this process was running.
I have now updated this script to use the new sync_folder_to_container method from pyrax. This method was introduced to pyrax in this commit. Make sure you update your pyrax modules before using this new script.
