Python bindings to the OpenStack Identity API (Keystone)

This is a client for the OpenStack Identity API, implemented by Keystone. There's a Python API (the keystoneclient module), and a command-line script (keystone).

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.

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=AUTH_URL)
>>> keystone.tenants.list()
>>> tenant = keystone.tenants.create(tenant_name="test", description="My new tenant!", enabled=True)
>>> tenant.delete()

Installing this package gets you a shell command, keystone, that you can use to interact with OpenStack'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 --os-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 bypass username/password authentication, you can provide a pre-established token. In Keystone, this approach is necessary to bootstrap the service with an administrative user, tenant & role (to do so, provide the client with the value of your admin_token defined in keystone.conf in addition to the URL of your admin API deployment, typically on port 35357):

export OS_SERVICE_TOKEN=thequickbrownfox-jumpsover-thelazydog
export OS_SERVICE_ENDPOINT=http://example.com:35357/v2.0

Since the Identity service can return multiple regions in the service catalog, you can specify the one you want with --os-region-name (or export OS_REGION_NAME):

export OS_REGION_NAME=north

Warning

If a region is not specified and multiple regions are returned by the Identity service, the client may not access the same region consistently.

You'll find complete documentation on the shell by running keystone help:

                        This option should be used with caution.
