#!/usr/bin/env python # -*- coding: utf-8 -*- ''' External inventory script for Abiquo ==================================== Shamelessly copied from an existing inventory script. This script generates an inventory that Ansible can understand by making API requests to Abiquo API Requires some python libraries, ensure to have them installed when using this script. This script has been tested in Abiquo 3.0 but it may work also for Abiquo 2.6. Before using this script you may want to modify abiquo.ini config file. This script generates an Ansible hosts file with these host groups: ABQ_xxx: Defines a hosts itself by Abiquo VM name label all: Contains all hosts defined in Abiquo user's enterprise virtualdatecenter: Creates a host group for each virtualdatacenter containing all hosts defined on it virtualappliance: Creates a host group for each virtualappliance containing all hosts defined on it imagetemplate: Creates a host group for each image template containing all hosts using it ''' # (c) 2014, Daniel Beneyto # # This file is part of Ansible, # # Ansible is free software: you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation, either version 3 of the License, or # (at your option) any later version. # # Ansible is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
