python-keystoneclient 0.4.1

Client Library for OpenStack Identity

Latest Version: 0.8.0

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__.

__ http://wiki.openstack.org/HowToContribute
__ http://github.com/openstack/python-keystoneclient

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=AUTH_URL)
    >>> keystone.tenants.list()
    >>> tenant = keystone.tenants.create(tenant_name="test", description="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 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.

If you need to connect to a server that is TLS-enabled (the auth URL begins
with 'https') and it uses a certificate from a private CA or a self-signed
certificate you will need to specify the path to an appropriate CA certificate
to use to validate the server certificate with ``--os-cacert`` or an
environment variable::

    export OS_CACERT=/etc/ssl/my-root-cert.pem

Certificate verification can be turned off using ``--insecure``. This should
be used with caution.

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

                            Tenant to request authorization on. Defaults to

    --os-token <service-token>
                            Specify an existing token to use instead of retrieving
                            one via authentication (e.g. with username &
                            password). Defaults to env[OS_SERVICE_TOKEN]
    --os-endpoint <service-endpoint>
                            Specify an endpoint to use instead of retrieving one
                            from the service catalog (via authentication).
                            Defaults to env[OS_SERVICE_ENDPOINT]
    --os-cacert <ca-certificate>
                            Specify a CA bundle file to use in verifying a TLS
                            (https) server certificate. Defaults to env[OS_CACERT]
    --insecure              Explicitly allow keystoneclient to perform "insecure"
                            TLS (https) requests. The server's certificate will
                            not be verified against any certificate authorities.
                            This option should be used with caution.
    --os-cert <certificate>
                            Defaults to env[OS_CERT]
    --os-key <key>          Defaults to env[OS_KEY]
    --os-cache              Use the auth token cache. Defaults to env[OS_CACHE]
    --force-new-token       If the keyring is available and in use, token will
                            always be stored and fetched from the keyring until
                            the token has expired. Use this option to request a
                            new token and replace the existing one in the keyring.
    --stale-duration <seconds>
                            Stale duration (in seconds) used to determine whether
                            a token has expired when retrieving it from keyring.
                            This is useful in mitigating process or network
                            delays. Default is 30 seconds.
