Client library for OpenStack Nova API

Project description

This is a client for the OpenStack Nova API. There’s a Python API (the novaclient module), and a command-line script (nova). Each implements 100% of the OpenStack Nova API.

[PENDING] 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.

This code a fork of Jacobian’s python-cloudservers If you need API support for the Rackspace API soley or the BSD license, you should use that repository. python-client is licensed under the Apache License like the rest of OpenStack.

Command-line API

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

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

export NOVA_USERNAME=openstack
export NOVA_API_KEY=yadayada
export NOVA_PROJECT_ID=myproject

You will also need to define the authentication url with --url. Or set it as an environment variable as well:

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

You’ll find complete documentation on the shell by running nova help:

usage: nova [--username USERNAME] [--apikey APIKEY]
                    [--projectid PROJECTID] [--url AUTH_URL] <subcommand> ...

Python API

[PENDING] There’s also a complete Python API.

By way of a quick-start:

>>> import novaclient
>>> nt = novaclient.OpenStack(USERNAME, API_KEY,PROJECT_ID [, AUTH_URL])
>>> nt.flavors.list()
>>> nt.servers.list()
>>> s = nt.servers.create(image=2, flavor=1, name='myserver')

... time passes ...

>>> s.reboot()

... time passes ...

>>> s.delete()

What’s new?
