Python bindings to the OpenStack Keystone API

This is a client for the OpenStack Keystone API. There's a Python API (the keystoneclient module), and a command-line script (keystone). The Keystone 2.0 API is still a moving target, so this module will remain in "Beta" status until the API is finalized and fully implemented.

Development takes place via the usual OpenStack processes as outlined in the `OpenStack wiki`_. The master repository is on GitHub__.

This code a fork of `Rackspace's python-novaclient`__ which is in turn a fork of `Jacobian's python-cloudservers`__. The python-keystoneclient is licensed under the Apache License like the rest of OpenStack.

Python API

By way of a quick-start:

# use v2.0 auth with http://example.com:5000/v2.0")
>>> from keystoneclient.v2_0 import client
>>> keystone = client.Client(username=USERNAME, password=PASSWORD, tenant_name=TENANT, auth_url=KEYSTONE_URL)
>>> keystone.tenants.list()
>>> tenant = keystone.tenants.create(name="test", descrption="My new tenant!", enabled=True)
>>> tenant.delete()

Command-line API

Installing this package gets you a shell command, keystone, that you can use to interact with Keystone's Identity API.

You'll need to provide your OpenStack tenant, username and password. You can do this with the --os_tenant_name, --os_username and --os_password params, but it's easier to just set them as environment variables:

export OS_TENANT_NAME=project
export OS_USERNAME=user
export OS_PASSWORD=pass

You will also need to define the authentication url with --os_auth_url and the version of the API with --identity_api_version. Or set them as an environment variables as well:

export OS_AUTH_URL=http://example.com:5000/v2.0
export OS_IDENTITY_API_VERSION=2.0

Alternatively, to authenticate to Keystone without a username/password, such as when there are no users in the database yet, use the service token and endpoint arguemnts. The service token is set in keystone.conf as admin_token; set it with service_token. Note: keep the service token secret as it allows total access to Keystone's database. The admin endpoint is set with --endpoint or SERVICE_ENDPOINT:

export SERVICE_TOKEN=thequickbrownfox-jumpsover-thelazydog
export SERVICE_ENDPOINT=http://example.com:35357/v2.0

Since Keystone can return multiple regions in the Service Catalog, you can specify the one you want with --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 keystone help:

usage: keystone [--os_username OS_USERNAME] [--os_password OS_PASSWORD]
                [--os_tenant_name OS_TENANT_NAME]
                [--os_tenant_id OS_TENANT_ID] [--os_auth_url OS_AUTH_URL]
                [--os_region_name OS_REGION_NAME]
                [--identity_api_version IDENTITY_API_VERSION] [--token TOKEN]
                [--endpoint ENDPOINT]
