The ironicclient python API lets you access ironic, the OpenStack Bare Metal Provisioning Service.
For example, to manipulate nodes, you interact with an ironicclient.v1.node object. You obtain access to nodes via attributes of the ironicclient.v1.client.Client object.
First, create an ironicclient.v1.client.Client instance by passing your credentials to ironicclient.client.get_client(). By default, the Bare Metal Provisioning system is configured so that only administrators (users with ‘admin’ role) have access.
Note
Explicit instantiation of ironicclient.v1.client.Client may cause errors since it doesn’t verify provided arguments, using ironicclient.client.get_client() is prefered way to get client object.
There are two different sets of credentials that can be used:
* ironic endpoint and auth token
* Identity Service (keystone) credentials
An auth token and the ironic endpoint can be used to authenticate:
* os_auth_token: authentication token (from Identity Service)
* ironic_url: ironic API endpoint, eg http://ironic.example.org:6385/v1
To create the client, you can use the API like so:
>>> from ironicclient import client
>>>
>>> kwargs = {'os_auth_token': '3bcc3d3a03f44e3d8377f9247b0ad155',
>>> 'ironic_url': 'http://ironic.example.org:6385/'}
>>> ironic = client.get_client(1, **kwargs)
These Identity Service credentials can be used to authenticate:
* os_username: name of user
* os_password: user's password
* os_auth_url: Identity Service endpoint for authorization
* insecure: Boolean. If True, does not perform X.509 certificate
validation when establishing SSL connection with identity
service. default: False (optional)
* os_tenant_{name|id}: name or ID of tenant
To create a client, you can use the API like so:
>>> from ironicclient import client
>>>
>>> kwargs = {'os_username': 'name',
>>> 'os_password': 'password',
>>> 'os_auth_url': 'http://keystone.example.org:5000/',
>>> 'os_tenant_name': 'tenant'}
>>> ironic = client.get_client(1, **kwargs)
Once you have an ironic Client, you can perform various tasks:
>>> ironic.driver.list() # list of drivers
>>> ironic.node.list() # list of nodes
>>> ironic.node.get(node_uuid) # information about a particular node
When the Client needs to propagate an exception, it will usually raise an instance subclassed from ironicclient.exc.BaseException or ironicclient.exc.ClientException.
