Apstra AOS external inventory script
|
|
====================================
|
|
|
|
Ansible has a feature where instead of reading from /etc/ansible/hosts
|
|
as a text file, it can query external programs to obtain the list
|
|
of hosts, groups the hosts are in, and even variables to assign to each host.
|
|
|
|
To use this:
|
|
- copy this file over /etc/ansible/hosts and chmod +x the file.
|
|
- Copy both files (.py and .ini) in your prefered directory
|
|
|
|
More information about Ansible Dynamic Inventory here
|
|
http://unix.stackexchange.com/questions/205479/in-ansible-dynamic-inventory-json-can-i-render-hostvars-based-on-the-hostname
|
|
|
|
2 modes are currently, supported: **device based** or **blueprint based**:
|
|
- For **Device based**, the list of device is taken from the global device list
|
|
the serial ID will be used as the inventory_hostname
|
|
- For **Blueprint based**, the list of device is taken from the given blueprint
|
|
the Node name will be used as the inventory_hostname
|
|
|
|
Input parameters parameter can be provided using either with the ini file or by using Environment Variables:
|
|
The following list of Environment Variables are supported: AOS_SERVER, AOS_PORT, AOS_USERNAME, AOS_PASSWORD, AOS_BLUEPRINT
|
|
The config file takes precedence over the Environment Variables
|
|
|
|
Tested with Apstra AOS 1.1
|
|
|
|
This script has been inspired by the cobbler.py inventory. thanks
