I use following:
cloudauth.py retrieves a key pair...
cloudclient.py is a simple wrapper around cloudmonkey so that we can use it
directly from python scripts and get json replies.
usage example:
def createZone(client):
try:
response = client.request('listZones')
if response['listzonesresponse']:
return response['listzonesresponse']['zone'][0]['id']
response = client.request('createZone',
{'name': 'default',
'networktype': 'Advanced',
'domain': 'ROOT',
'dns1': PARAMS['external_dns'],
'internaldns1': PARAMS['internal_dns']})
return response['createzoneresponse']['zone']['id']
except Exception as e:
print 'Error while creating a zone:'
print e
raise
