Python bindings to Rackspace's Cloud Servers API

Python bindings to the Rackspace Cloud Servers API

This is a client for Rackspace's Cloud Servers API. There's a Python API (the cloudservers module), and a command-line script (cloudservers). Each implements 100% of the Rackspace API.

Full documentation is available.

You'll also probably want to read Rackspace's API guide (PDF) -- the first bit, at least -- to get an idea of the concepts. Rackspace 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. Bug reports and patches may be filed there.

Command-line API

Installing this package gets you a shell command, cloudservers, that you can use to interact with any Rackspace compatible API (including OpenStack).

You'll need to provide your Rackspace username and API key. You can do this with the --username and --apikey params, but it's easier to just set them as environment variables:

export CLOUD_SERVERS_USERNAME=jacobian
export CLOUD_SERVERS_API_KEY=yadayada

If you are using OpenStack or another Rackspace compatible API, you can optionally define its authentication url with --url. Or set it as an environment variable as well:

export CLOUD_SERVERS_URL=http://myserver:port/v1.0/

You'll find complete documentation on the shell by running cloudservers help:

usage: cloudservers [--username USERNAME] [--apikey APIKEY] 
                    [--url AUTH_URL] <subcommand> ...

Command-line interface to the Cloud Servers API.

    show                Show details about the given server.

Optional arguments:

  --apikey APIKEY       Defaults to env[CLOUD_SERVERS_API_KEY].
  --url AUTH_URL        Defaults to env[CLOUD_SERVERS_URL] or
                        https://auth.api.rackspacecloud.com/v1.0
                        if undefined. 

See "cloudservers help COMMAND" for help on a specific command.

Python API

There's also a complete Python API.

By way of a quick-start:

>>> import cloudservers
>>> cs = cloudservers.CloudServers(USERNAME, API_KEY [, AUTH_URL])
>>> cs.flavors.list()
[...]
>>> cs.servers.list()
[...]
>>> s = cs.servers.create(image=2, flavor=1, name='myserver')

... time passes ...

>>> s.reboot()

... time passes ...

>>> s.delete()

FAQ

What's wrong with libcloud?

Nothing! However, as a cross-service binding it's by definition lowest common denominator; I needed access to the Rackspace-specific APIs (shared IP groups, image snapshots, resizing, etc.). I also wanted a command-line utility.
