|
|
|
|
HOW-TO:
|
|
The simplest way to create a client instance is initialization with your
|
|
credentials::
|
|
|
|
>>> from freezerclient import client
|
|
>>> freezer = client.Client('2',username='admin',password='stack')
|
|
|
|
Here ``VERSION`` is freezer API Version, you can use ``1``(v1) or ``2``
|
|
(v2),default is API v2.
|
|
|
|
Alternatively, you can create a client instance using the keystoneauth
|
|
session API. See "The freezerclient Python API" page at
|
|
python-freezerclient's doc.
