Chameleon OpenStack and libcloud

[Massimo Canonico <ma...@uniupo.it>]

Hi all,

after some interaction with the Chameleon guys, we figure out how we can 
use libcloud and Chemeleon OpenStack.

I paste after my signature the procedure and the working script in case 
someone else get the same problem as me.

Best,

Massimo.

# Before to run this script you must:
# 1) Download the OpenStack RC file
# 2) run 'source <openrc file>' and input your CLI password
# 3) run 'openstack token issue'
# 4) replace <token> below with the token you get from the openstack command

from libcloud.compute.types import Provider
from libcloud.compute.providers import get_driver

auth_username = 'your_username'
auth_password = 'your_passwors'
project_name = 'your_project_name' # It should look like CH-XXXXX or 
CCC-19/20

auth_url = 'https://kvm.tacc.chameleoncloud.org:5000/v3'  # It should 
look like https://kvm.tacc.chameleoncloud.org:5000
region_name = 'KVM@TACC' # It should looks like KVM@TACC

cls = get_driver(Provider.OPENSTACK)

driver = cls(auth_username,auth_password,
                 ex_domain_name="chameleon",
                 ex_tenant_name=project_name,
ex_force_base_url='https://kvm.tacc.chameleoncloud.org:8774/v2.1',
                 ex_force_auth_url=auth_url,
                 ex_force_auth_version='3.x_password',
                 ex_force_auth_token='<token>')

images = driver.list_images()

i = 1
for image in images:
     print(i,"):",images.name)
     i += 1
