Python bindings to the OpenStack Cinder API

This is a customer 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 control-line tool. You lot may as well want to look at the OpenStack API documentation.

The project is hosted on Launchpad, where bugs can exist filed. The lawmaking is hosted on OpenStack. Patches must be submitted using Gerrit.

Command-line API

Installing this parcel gets yous a beat out command, cinder, that y'all can use to interact with whatever 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 --bone-tenant-proper name params, but it's easier to just fix them as surroundings 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 besides. 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:

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

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

You lot'll notice complete documentation on the shell by running cinder help:

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

If you desire to get a item version API help message, you can add --os-volume-api-version <volume-api-ver> in help command, similar this:

cinder --bone-volume-api-version three.28 assistance          

Python API

There'south also a consummate Python API, but it has non yet been documented.

Quick-start using keystone:

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