=======================
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
:py:class:`ironicclient.v1.node.Node` object.
You obtain access to nodes via attributes of the
:py:class:`ironicclient.v1.client.Client` object.
Usage
=====
Get a Client object
-------------------
First, create an :py:class:`ironicclient.v1.client.Client` instance by passing
your credentials to :py:meth:`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 :py:class:`ironicclient.v1.client.Client` may
cause errors since it doesn't verify provided arguments, using
:py:meth:`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 :py:class:`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
:py:class:`ironicclient.common.apiclient.exceptions.ClientException`.
Refer to the modules themselves, for more details.
