Python bindings to the OpenStack Nova API
This is a client for the OpenStack Nova API. There's a Python API (the
novaclient module), and a command-line script (
implements 100% of the OpenStack Nova API.
[PENDING] Full documentation is available.
You'll also probably want to read OpenStack Compute Developer Guide API -- 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.
This code a fork of Jacobian's python-cloudservers If you need API support for the Rackspace API solely or the BSD license, you should use that repository. python-client is licensed under the Apache License like the rest of OpenStack.
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
--projectid params, but it's
easier to just set them as environment variables:
export NOVA_USERNAME=openstack export NOVA_PASSWORD=yadayada export NOVA_PROJECT_ID=myproject
You will also need to define the authentication url with
--url and the
version of the API with
--version. Or set them as an environment
variables as well:
export NOVA_URL=http://example.com:8774/v1.1/ export NOVA_VERSION=1.1
If you are using Keystone, you need to set the NOVA_URL to the keystone endpoint:
Since Keystone can return multiple regions in the Service Catalog, you
can specify the one you want with
export NOVA_REGION_NAME). It defaults to the first in the list returned.
You'll find complete documentation on the shell by running

Optional arguments: --username USERNAME Defaults to env[NOVA_USERNAME]. --password PASSWORD Defaults to env[NOVA_PASSWORD]. --projectid PROJECTID Defaults to env[NOVA_PROJECT_ID]. --url AUTH_URL Defaults to env[NOVA_URL] or https://auth.api.rackspacecloud.com/v1.0 if undefined. --version VERSION Accepts 1.1, defaults to env[NOVA_VERSION]. --region_name NAME The region name in the Keystone Service Catalog to use after authentication. Defaults to first in the list returned. See "nova help COMMAND" for help on a specific command.
[PENDING] There's also a complete Python API.
By way of a quick-start:
>>> import novaclient >>> nt = novaclient.OpenStack(USERNAME, PASSWORD, 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()
Quick-start using keystone:
# use v2.0 auth with http://example.com:5000/v2.0/") >>> from novaclient.v1_1 import client >>> nt = client.Client(USER, PASS, TENANT, AUTH_URL) >>> nt.flavors.list() [...] >>> nt.servers.list() [...] >>> nt.keypairs.list() [...]
