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).
This code is a fork of Rackspace's python-novaclient which is in turn a fork of Jacobian's python-cloudservers. 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):
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:
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:

Optional arguments: --version Shows the client version and exits --timeout <seconds> Set request timeout (in seconds) --os-username <auth-user-name> Name used for authentication with the OpenStack Identity service. Defaults to env[OS_USERNAME] --os-password <auth-password> Password used for authentication with the OpenStack Identity service. Defaults to env[OS_PASSWORD] --os-tenant-name <auth-tenant-name> Tenant to request authorization on. Defaults to env[OS_TENANT_NAME] --os-tenant-id <tenant-id> Tenant to request authorization on. Defaults to env[OS_TENANT_ID] --os-auth-url <auth-url> Specify the Identity endpoint to use for authentication. Defaults to env[OS_AUTH_URL] --os-region-name <region-name> Defaults to env[OS_REGION_NAME] --os-identity-api-version <identity-api-version> Defaults to env[OS_IDENTITY_API_VERSION] or 2.0 --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. See "keystone help COMMAND" for help on a specific command.
