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.
Contents:
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]

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, 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() [...]
