Top-level object to access the OpenStack Compute API.
|
|
|
|
Create an instance with your creds::
|
|
|
|
>>> client = Client(USERNAME, PASSWORD, PROJECT_ID, AUTH_URL)
|
|
|
|
Or, alternatively, you can create a client instance using the
|
|
keystoneclient.session API::
|
|
|
|
>>> 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)
|
|
|
|
Then call methods on its managers::
|
|
|
|
>>> client.servers.list()
|
|
...
|
|
>>> client.flavors.list()
|
|
...
|
|
|
|
It is also possible to use an instance as a context manager in which
|
|
case there will be a session kept alive for the duration of the with
|
|
statement::
|
|
|
|
>>> with Client(USERNAME, PASSWORD, PROJECT_ID, AUTH_URL) as client:
|
|
... client.servers.list()
|
|
... client.flavors.list()
|
|
...
|
|
|
|
It is also possible to have a permanent (process-long) connection pool,
|
|
by passing a connection_pool=True::
|
|
|
|
>>> client = Client(USERNAME, PASSWORD, PROJECT_ID,
|
|
... AUTH_URL, connection_pool=True)
