#!/bin/bash
export OS_PROJECT_DOMAIN_ID=default
export OS_USER_DOMAIN_ID=default
export OS_PROJECT_NAME=admin
export OS_TENANT_NAME=admin
export OS_USERNAME=admin

#!/usr/bin/python
from os import environ as env
import keystoneclient.v2_0.client as ksclient
keystone = ksclient.Client(auth_url=env['OS_AUTH_URL'],
                           username=env['OS_USERNAME'],
                           password=env['OS_PASSWORD'],

from credentials import get_nova_credentials_v2
from novaclient.client import Client

credentials = get_nova_credentials_v2()
nova_client = Client(**credentials)

print(nova_client.servers.list())
