Client library for OpenStack Nova API.

Project description

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

[PENDING] Full documentation is available.

You’ll also probably want to read OpenStack Compute Developer Guide API – the first bit, at least – to get an idea of the concepts. Rackspace is doing the cloud hosting thing a bit differently from Amazon, and if you get the concepts this library should make more sense.

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-client 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_COMPUTE_API_VERSION=1.1

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:

usage: cinder [--debug] [--os_username OS_USERNAME] [--os_password OS_PASSWORD]
            [--os_tenant_name OS_TENANT_NAME] [--os_auth_url OS_AUTH_URL]
            [--os_region_name OS_REGION_NAME] [--service_type SERVICE_TYPE]
            [--service_name SERVICE_NAME] [--endpoint_type ENDPOINT_TYPE]
            [--version VERSION] [--username USERNAME]
            [--region_name REGION_NAME] [--apikey APIKEY]
            [--projectid PROJECTID] [--url URL]

See "cinder help COMMAND" for help on a specific command.

Python API

[PENDING] There’s also a complete Python API.

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="compute")
>>> nt.flavors.list()
[...]
>>> nt.servers.list()
[...]
>>> nt.keypairs.list()
[...]

What’s new?

[PENDING] See the release notes.
