The `novaclient` Python API

Usage

First create a client instance with your credentials:html

 
   >>> from novaclient.client import Client >>> nova = Client(VERSION, USERNAME, PASSWORD, PROJECT_ID, AUTH_URL)  
  

Here VERSION can be: 1.1, 2 and 3.python

Alternatively, you can create a client instance using the keystoneclient session API:ubuntu

 
   >>> from keystoneclient.auth.identity import v2 >>> from keystoneclient import session >>> from novaclient.client import Client >>> auth = v2.Password(auth_url=AUTH_URL,  username=USERNAME,  password=PASSWORD,  tenant_name=PROJECT_ID) >>> sess = session.Session(auth=auth) >>> nova = client.Client(VERSION, session=sess)  
  

For more information on this keystoneclient API, see Using Sessions.api

Then call methods on its managers:session

>>> nova.servers.list() [<Server: buildslave-ubuntu-9.10>] >>> nova.flavors.list() [<Flavor: 256 server>,  <Flavor: 512 server>,  <Flavor: 1GB server>,  <Flavor: 2GB server>,  <Flavor: 4GB server>,  <Flavor: 8GB server>,  <Flavor: 15.5GB server>] >>> fl = nova.flavors.find(ram=512) >>> nova.servers.create("my-server", flavor=fl) <Server: my-server>
