Python bindings to the OpenStack Cinder API
===========================================

This is a client for the OpenStack Cinder API. There's a Python API (the
``cinderclient`` module), and a command-line script (``cinder``). Each
implements 100% of the OpenStack Cinder API.

See the `OpenStack CLI guide`_ for information on how to use the ``cinder``
command-line tool. You may also want to look at the
`OpenStack API documentation`_.

.. _OpenStack API documentation: http://docs.openstack.org/api/

The project is hosted on `Launchpad`_, where bugs can be filed. The code is
hosted on `Github`_. Patches must be submitted using `Gerrit`_, *not* Github
pull requests.

Command-line API
----------------

Installing this package gets you a shell command, ``cinder``, that you
can use to interact with any Rackspace compatible API (including OpenStack).

You'll need to provide your OpenStack username and password. You can do this
with the ``--os-username``, ``--os-password`` and  ``--os-tenant-name``
params, but it's easier to just set them as environment variables::

    export OS_USERNAME=openstack
    export OS_PASSWORD=yadayada
    export OS_TENANT_NAME=myproject

You will also need to define the authentication url with ``--os-auth-url``
and the version of the API with ``--os-volume-api-version``.  Or set them as
environment variables as well::

    export OS_AUTH_URL=http://example.com:8774/v1.1/
    export OS_VOLUME_API_VERSION=1

If you are using Keystone, you need to set the OS_AUTH_URL to the keystone
endpoint::

    export OS_AUTH_URL=http://example.com:5000/v2.0/

Since Keystone can return multiple regions in the Service Catalog, you
can specify the one you want with ``--os-region-name`` (or
``export OS_REGION_NAME``). It defaults to the first in the list returned.

You'll find complete documentation on the shell by running
``cinder help``::

    usage: cinder [--debug] [--os-username <auth-user-name>]
                  [--os-password <auth-password>]
                  [--os-tenant-name <auth-tenant-name>] [--os-auth-url <auth-url>]

Python API
----------

There's also a complete Python API, but it has not yet been documented.

Quick-start using keystone::

    # use v2.0 auth with http://example.com:5000/v2.0/")
    >>> from cinderclient.v1 import client
    >>> nt = client.Client(USER, PASS, TENANT, AUTH_URL, service_type="volume")
    >>> nt.volumes.list()
    [...]
