Python API
==========
In order to use the Python api directly, you must first obtain an auth token
and identify which endpoint you wish to speak to. Once you have done so, you
can use the API like so::
>>> from cinderclient import client
>>> cinder = client.Client('1', $OS_USER_NAME, $OS_PASSWORD, $OS_PROJECT_NAME, $OS_AUTH_URL)
>>> cinder.volumes.list()
[]
>>> myvol = cinder.volumes.create(display_name="test-vol", size=1)
>>> myvol.id
ce06d0a8-5c1b-4e2c-81d2-39eca6bbfb70
>>> cinder.volumes.list()
[<Volume: ce06d0a8-5c1b-4e2c-81d2-39eca6bbfb70>]
>>> myvol.delete()
Alternatively, you can create a client instance using the keystoneauth session
API::
>>> from keystoneauth1 import loading
>>> from keystoneauth1 import session
>>> from cinderclient import client
>>> loader = loading.get_plugin_loader('password')
>>> auth = loader.load_from_options(auth_url=AUTH_URL,
... username=USERNAME,
... password=PASSWORD,
... project_id=PROJECT_ID,
... user_domain_name=USER_DOMAIN_NAME)
>>> sess = session.Session(auth=auth)
>>> cinder = client.Client(VERSION, session=sess)
>>> cinder.volumes.list()
[]
