Access Nova Compute via Python

General Overview

This is a VERY Simple libary that I have found useful in projects where the I needed access to the NOVA API.

Functions of the Library :
  • Do Openstack Nova Things
  • Presently only supports Nova Compute, but does so for both Vanilla Openstack and the Rackspace Open Cloud
Prerequisites :
  • Python => 2.6 but < 3.0

Installation :

Installation is simple:

git clone git://github.com/cloudnull/bookofnova.git
cd bookofnova
python setup.py install

Now in your application Import bookofnova and go forth and Access Openstack Nova.

Application Usage

Here is some Basic Usage –

# Everything in this dictionary is a string, fill in the needed values.
m_args = {"os_user": 'YOU',
          "os_apikey": 'RANDOMNUMBERSANDTHINGS',
          "os_auth_url": None,
          "os_rax_auth": 'ALOCATION',
          "os_verbose": None,
          "os_password": None,
          "os_tenant": None,
          "os_region": None,
          "os_version": 'v2.0'}
from __future__ import print_function
from bookofnova import authentication, computelib, connections

# Set output / Logging
output = print

# Authentication with Nova
auth = authentication.Authentication(m_args=m_args,
                                     output=output)
service_cat = auth.os_auth()

# Tell the book of Nova that you are ready
nova = computelib.NovaCommands(m_args=m_args,
                               output=output)

# Using Nova to show a list of all Instances
servers = nova.server_list()
print(servers)

# now everything that you ever wanted to know from a Openstack Nova
# query can be found in your dictionary under the key 'nova_resp'
