By Default the application now uses the standard Python Logging Module, and will print out all of the logging information to the console as you access the library. If you want to log to a file simply change the “log_file” variable when you load in “computelib.NovaCommands” class. The “log_file” variable will attempt to place the log file in “/var/log” if you are running with elevated privileges, otherwise the log file will be in the users working directory. You may also change the log level for more/less output by changing the “log_level” variable. Lastly, if you have a log handler setup you can override the default logger entirely by simple using the “output” variable. To use the output variable you will need to pre-set the some logging facility which supports [error, info, debug].Functions of the Library :Do Openstack Nova ThingsPresently only supports Openstack Nova Compute, but does so for both Vanilla Openstack and the Rackspace Open CloudNot all of the functions are built-in however the library is extendable and I would be happy to add things in as needed / requested.Prerequisites :Python => 2.6 but < 3.0Installation is simple :gitclonegit://github.com/cloudnull/bookofnova.gitcdbookofnovapythonsetup.pyinstallNow in your applicationImport bookofnovaand go forth and Access Openstack Nova.Application UsageHere is some Basic Usage :# Everything in this dictionary is a string, fill in the needed values.m_args={"os_user":'YOURUSERNAME',"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'}frombookofnovaimportcomputelib,connections# Tell the book of Nova that you are readynova=computelib.NovaCommands(m_args=m_args,log_file=None,log_level='info',output=None)# Authenticate Against the Nova APInova.auth()# Using Nova to show a list of all Instancesservers=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'Get SocialDownloadable onPyPiDownloadable onGitHubSee MyGitHub Issues Pagefor any and all Issues or Feature requestsSeehttps://github.com/cloudnull/bookofnova/issuesfor Issues or Feature requestsLicenseCopyright [2013] [Kevin Carter]Licensed under the Apache License, Version 2.0 (the “License”);
