ironicclient Python API

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.Node object. You obtain access to nodes via attributes of the ironicclient.v1.client.Client object.

Usage

Get a 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 preferred 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

Using ironic endpoint and auth token

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)

Using Identity Service (keystone) credentials

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

Also the following parameters are required when using the Identity API v3:

* os_user_domain_name: name of a domain the user belongs to,
  usually 'default'
* os_project_domain_name: name of a domain the project belongs to,
  usually 'default'

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_project_name': 'project'}
>>> ironic = client.get_client(1, **kwargs)

Perform ironic operations

Once you have an ironicclient.v1.client.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.common.apiclient.exceptions.ClientException.
