get_volume_api_version_from_endpoint currently assumes that the management_url will always be in the format of http://<ip>:<port>/vX/<tenant_id>. Customers using a gateway, however, can get a mangement_url in a different form like https://<ip>:<port>/<resource>/vX/<tenant_id>. This causes the get_volume_api_version_from_endpoint to find the resource portion of the url when looking for the Volume API version which makes the cinder client unusable. To resolve this I have implemented an exception handler in the case that get_volume_api_version_from_endpoint fails. If the exception is thrown, I check for OS_VOLUME_API_VERSION in the environment and use the value of that environment variable, if it is set, to determine the API version to use. There are proposals to fix this via changes to keystone in future releases, but this provides a way for IaaS Gateway users to proceed with Havana.

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
--version. Or set them as an 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 CINDER_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:

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()
