OpenStack Python-novaclient

Question

I'm trying this toy code to initiate myself to the python-novaclient lib

#!/usr/bin/python

from novaclient.client import Client


   nova = Client(2, "####", "####", "####" , "####:8774/v2.0")
   _test = nova.images.list()

   print _test

but I always get this error:

does anyone know what kind of problem this could be?

Answer 1

You're using the python-novaclient as a library and it was never designed to be used that way. It's a CLI that people unfortunately use as a library.

Give the official Python OpenStack SDK a try.

pip install openstacksdk

The code for listing images.

import sys

from openstack import connection
from openstack import profile
from openstack import utils

utils.enable_logging(True, stream=sys.stdout)

prof = profile.Profile()
prof.set_region(prof.ALL, "RegionOne")

conn = connection.Connection(
    auth_url='https://my.identity.endpoint/v2.0/',
    profile=prof,
    username="my_username",
    password="my_password")

for image in conn.compute.images():
    print(image)

Answer 2

you just need a good example, please refer to: http://docs.openstack.org/developer/python-novaclient/api.html

>>> from novaclient import client
>>> nova = client.Client(VERSION, USERNAME, PASSWORD, PROJECT_ID, AUTH_URL)

particularly, if your username is admin, password is password, project name is admin, keystone endpoint is http://127.0.0.1:5000 , then it should be

>>> nova = client.Client(2, 'admin', 'password', 'admin', 'http://127.0.0.1:5000')

note that auth url is keystone endpoint, NOT nova endpoint.
