A client for the Nectar Allocation API.
First create a client instance using the keystoneauth session API:
>>> from keystoneauth1 import loading >>> from keystoneauth1 import session >>> from nectarallocationclient import client >>> loader = loading.get_plugin_loader('password') >>> auth = loader.load_from_options(auth_url=AUTH_URL, ... username=USERNAME, ... password=PASSWORD, ... project_name=PROJECT_NAME, ... user_domain_id='default', ... project_domain_id='default' ) >>> sess = session.Session(auth=auth) >>> nectar = client.Client(VERSION, session=sess)
Here VERSION
can currently only be 1
.
If you have PROJECT_ID instead of a PROJECT_NAME, use the project_id parameter. Similarly, if your cloud uses keystone v3 and you have a DOMAIN_NAME or DOMAIN_ID, provide it as user_domain_(name|id) and if you are using a PROJECT_NAME also provide the domain information as project_domain_(name|id).
nectarallocationclient adds 'python-nectarallocationclient' and its version to the user-agent string that keystoneauth produces. If you are creating an application using nectarallocationclient and want to register a name and version in the user-agent string, pass those to the Session:
>>> sess = session.Session( ... auth=auth, app_name'nodepool', app_version'1.2.3')
If you are making a library that consumes nectarallocationclient but is not an end-user application, you can append a (name, version) tuple to the session's additional_user_agent property:
>>> sess = session.Session(auth=auth) >>> sess.additional_user_agent.append(('shade', '1.2.3'))
For more information on this keystoneauth API, see Using Sessions.
Then call methods on its managers:
>>> nectar.allocations.list() [<Allocation: 1 (my-cool-project)>] >>> nectar.allocations.create("new-project",....) <Allocation: 2 (new-project)>
