Client library for the Cinder API

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.

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.

This code a fork of Jacobian's python-cloudservers If you need API support for the Rackspace API solely or the BSD license, you should use that repository. python-cinderclient is licensed under the Apache License like the rest of OpenStack.

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>]
              [--os-region-name <region-name>] [--service-type <service-type>]

              [--endpoint-type <endpoint-type>]
              [--os-volume-api-version <compute-api-ver>]
              [--os-cacert <ca-certificate>] [--retries <retries>]

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()
[...]
