Python bindings to the OpenStack Cinder API

.. image:: https://img.shields.io/pypi/v/python-cinderclient.svg :target: https://pypi.org/project/python-cinderclient/ :alt: Latest Version

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 Reference_ for information on how to use the cinder command-line tool. You may also want to look at the OpenStack API documentation_.

.. _OpenStack CLI Reference: https://docs.openstack.org/python-openstackclient/latest/cli/ .. _OpenStack API documentation: https://docs.openstack.org/api-quick-start/

The project is hosted on Launchpad, where bugs can be filed. The code is hosted on OpenStack. Patches must be submitted using Gerrit_.

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. Since Block Storage API V2 is officially deprecated, you are encouraged to set OS_VOLUME_API_VERSION=3. If you are using Keystone, you need to set the OS_AUTH_URL to the keystone endpoint::

export OS_AUTH_URL=http://controller:5000/v3
export OS_VOLUME_API_VERSION=3

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::

Run "cinder help SUBCOMMAND" for help on a subcommand.

If you want to get a particular version API help message, you can add --os-volume-api-version <volume-api-ver> in help command, like this::

cinder --os-volume-api-version 3.28 help

Python API

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

Quick-start using keystone::

# use v3 auth with http://controller:5000/v3
>>> from cinderclient.v3 import client
>>> nt = client.Client(USERNAME, PASSWORD, PROJECT_ID, AUTH_URL)
>>> nt.volumes.list()
[...]
