Ansible CloudStack external inventory script.
|
||||
=============================================
|
||||
|
||||
Generates Ansible inventory from CloudStack. Configuration is read from
|
||||
'cloudstack.ini'. If you need to pass the project, write a simple wrapper
|
||||
script, e.g. project_cloudstack.sh:
|
||||
|
||||
#!/bin/bash
|
||||
cloudstack.py --project <your_project> $@
|
||||
|
||||
|
||||
When run against a specific host, this script returns the following attributes
|
||||
based on the data obtained from CloudStack API:
|
||||
|
||||
"web01": {
|
||||
