novaclient-auth-secretkey

This is an authentication plugin for python-novaclient. It allows novaclient users to specify an API key+secret key as credentials to the Keystone authentication service instead of the normal username+password.

Plugin users can specify the credentials either programmatically as attributes of the httpclient object, or using environment variables (e.g. when using the command-line nova client).

Quick Start

  • Install the plugin:

    pip install novaclient-auth-secretkey

  • Set your environment variables in your shell:

    # this plugin uses these values:
export OS_AUTH_SYSTEM="secretkey
export OS_ACCESS_KEY_ID="FIBVLEKFOSIFJS68FI8L"
export OS_SECRET_KEY="Mu8E/fsleibv8f2j7G97pzqKusive8ofieFkeNs1"


# this is standard python-novaclient stuff.  these values would connect to
# hpcloud's us west az3:
export OS_REGION_NAME="az-3.region-a.geo-1"
export OS_AUTH_URL=https://region-a.geo-1.identity.hpcloudsvc.com:35357/v2.0/
export [email protected]


# you still have to trick python-novaclient into instantiating the objects
# correctly, but you do *not* have to use your actual username and password
# here:
export OS_PASSWORD=useapikey
export OS_USERNAME=useapikey

  • Test it out:

    nova list

Library Usage

If you're using python-novaclient as a library, instead of letting the library use values from the environment, you probably want to control what values you pass to the objects you instantiate. This is how you would use the API key and secret with a novaclient.client.Client object:

from novaclient.client import Client


ACCESS_KEY_ID = 'FIBVLEKFOSIFJS68FI8L'
SECRET_KEY = 'Mu8E/fsleibv8f2j7G97pzqKusive8ofieFkeNs1'
TENANT_NAME = '[email protected]'
AUTH_URL = 'https://region-a.geo-1.identity.hpcloudsvc.com:35357/v2.0/'
REGION_NAME = 'az-3.region-a.geo-1'

nova = Client('2', 'dummyvalue', 'dummyvalue', TENANT_NAME,
        auth_system='secretkey', auth_url=AUTH_URL, region_name=REGION_NAME)

# the constructor does not accept the plugin values, so the plugin just
# looks for them as attributes of the nova.client object
nova.client.os_access_key_id = ACCESS_KEY_ID
nova.client.os_secret_key = SECRET_KEY

nova.authenticate()

In case both the environment variables and the object attributes are specified, the values from the object attributes take precedence.
