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
|
|
