This is a client for the OpenStack Compute API used by Rackspace Cloud and others. There’s a Python API (the openstack.compute module), and a command-line script (installed as openstack-compute). Each implements the entire OpenStack Compute API (as well as a few Rackspace-only addons).
To try this out, you’ll need a Rackspace Cloud account — or your own install of OpenStack Compute (also known as Nova). If you’re using Rackspace you’ll need to make sure to sign up for both Cloud Servers and Cloud Files – Rackspace won’t let you get an API key unless you’ve got a Cloud Files account, too. Once you’ve got an account, you’ll find your API key in the management console under “Your Account”.
You may want to read Rackspace’s API guide (PDF) – the first bit, at least – to get an idea of the concepts. Rackspace/OpenStack is doing the cloud hosting thing a bit differently from Amazon, and if you get the concepts this library should make more sense.
Development takes place on GitHub; please file bugs/pull requests there.
