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`_ 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 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
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
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)
Perform ironic operations
-------------------------
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`_.
Refer to the modules themselves, for more details.
