Windows Azure external inventory script
|
|
||||||
=======================================
|
|
||||||
|
|
||||||
Generates inventory that Ansible can understand by making API request to
|
|
||||||
Windows Azure using the azure python library.
|
|
||||||
|
|
||||||
NOTE: This script assumes Ansible is being executed where azure is already
|
|
||||||
installed.
|
|
||||||
|
|
||||||
pip install azure
|
|
||||||
|
|
||||||
Adapted from the ansible Linode plugin by Dan Slimmon.
