Using the CloudStack API From Python

I've recently been playing around with the Private Cloud at work. They're using VMWare and they've provided a CloudStack API layer that allowed me write my own command line tools in Python.

 A couple of things you'll need to get started -
  • You'll need your 'API key' and your 'Secret'. These should be available through whatever UI your infrastructure provides
  • You will need the CloudStack client for Python
  • I'm also using the Termcolor package to prettify my console output in the examples below
I've created two files with Constants. The first, is called nikkeys.py. You will need to replace the examples below with your own keys. This file contains just two constants -

apikey = 'YOUR_API_KEY'
secret = 'YOUR_SECRET_KEY'

The second file is called cloudconstants.py and contains information about the cloud environment. Eventually you would want to get rid of this file otherwise you would need to update it regularly. These constants are the GUIDs for the various resources (the GUIDs below are fake they've been replaced by random GUIDs) -

api = 'http://your.cloudstack.url.com/client/api'

NIce Post, I tried using the same way but ended up with the below error.

cloudstack.cloud_exceptions.CloudException: Account error

Can you please suggest.

Code:

import cloudstack
from cloudstack import Client

api = 'xxx'
apikey = 'yyy'
secretkey = 'zzz'
cloud = cloudstack.Client(api, apikey, secretkey)

Hi Sri. The code only works with Python 2.x. Aside from that I've never encountered this error before. 

I'm not really an expert but 'account error' seems to suggest that API access might not have been set up correctly. You're better of posting to a public forum.

The Forecaster Brown Fan Club





















  I spent the last couple of weeks in October watching what could only be described as the Idiot's Guide to the Wikipedia entry on Hurricane Sandy, otherwise known as the Weather Channel (it was the only live channel I could find online).   Half of it involved presenters with an emotional age of 14 trying to get as close to the storm surge as they could, while Dr. Thang in Atlanta helpfully pointed out the eye of the storm every so often.     It left me wondering why India had fought so hard  for a Cray XMP-24  all those decades ago when all they needed was a helicopter, a doppler, a satellite photo and a half-crazed adolescent with a death-wish.     Then I came across this page  written by the imaginately named 'Forecaster Brown'. The post, dated ' 1100 AM EDT SAT OCT 27 2012 ' begins   " NOAA AND AIR FORCE RESERVE HURRICANE HUNTER AIRCRAFT HAVE BEEN  SAMPLING THE CYCLONE THIS MORNING.

How to Create a Pentaho Report Using the REST Client

   Prerequisites   Pentaho Kettle (see earlier blog post)  Pentaho Report Designer  You will get an error message in Pentaho Report Designer that says ' java.lang.NoClassDefFoundErr: com/sun/jersey/api/client/ClientConfig ' if you try to run a report against the Kettle job. To fix this error copy the following files from  C:\pentaho\data-integration\libext\jersey\ to C:\pentaho\prd-ce-3.9.1-GA\report-designer\lib\. If you plan to ublish the report to the BI Server, also copy these files to C:\pentaho\biserver-ce\tomcat\webapps\pentaho\WEB-INF\lib\ as well -   jersey-apache-client-1.7.jar  jersey-client-1.7.jar  jersey-core-1.7.jar     The Payload    My example returns an array of objects     [      {             "id":"1",             "name":"item1",             "description":"someDescription1"      },        {             "id":"2",             "name":"item2",             "de

Automated Testing with vncdotool (Not Headless, but Hairless)




















Image







  The headless testing problem is a thorny one and impacts the fundamental architecture of the test automation platform I'm working on. If we can't find a solution, we might not be able to use the private cloud nor parallelize our testing effectively.     Part of the problem are the tests themselves that still rely on SendKeys() and MouseMove(). Two aspects of remote interaction that are insecure and therefore disallowed by Microsoft from Windows Vista onwards. This means that we have to rely on hacks like the VIX API and the one that I am about to document below.     There are two widely-used technologies for remote interactive connectivity on the Windows platform - the Remote Desktop Client (RDC) and VNC. The first is entirely proprietary while the second offers a number of open-source implementations (and some proprietary, full-featured, commercial implementations). The RDC implementation requires access to the VIX API which in turn relies on proprietary, privileged access t
