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 (``nova``). Each
|
|
implements 100% of the OpenStack Nova API.
|
|
|
|
[PENDING] `Full documentation is available`__.
|
|
|
|
__ http://packages.python.org/python-novaclient/
|
|
|
|
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.
|
|
|
|
__ http://docs.rackspacecloud.com/servers/api/cs-devguide-latest.pdf
|
|
|
|
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`` 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::
|
|
|
|
export NOVA_URL=http://example.com:5000/v2.0/
|
|
|
|
Since Keystone can return multiple regions in the Service Catalog, you
|
|
can specify the one you want with ``--region_name`` (or
|
|
``export NOVA_REGION_NAME``). It defaults to the first in the list returned.
|
|
|
|
You'll find complete documentation on the shell by running
|
|
``nova help``::
|
|
|
|
usage: nova [--username USERNAME] [--apikey APIKEY] [--projectid PROJECTID]
|
|
[--url URL] [--version VERSION] [--region_name NAME]

Python API
|
|
----------
|
|
|
|
[PENDING] There's also a `complete Python API`__.
|
|
|
|
__ http://packages.python.org/python-novaclient/
|
|
|
|
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()
|
|
|
|
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()
|
|
[...]
|
|
|
|
# if you want to use the keystone api to modify users/tenants:
|
|
>>> from novaclient import client
|
|
>>> conn = client.HTTPClient(USER, PASS, TENANT, KEYSTONE_URL)
|
|
>>> from novaclient import keystone
|
|
>>> kc = keystone.Client(conn.client)
|
|
>>> kc.tenants.list()
|
|
[...]
