MAAS Dynamic Inventory for Ansible

Getting Started

This script is meant to act as a dynamic inventory for MAAS.

NOTE: First run of of the script might take a long time. The file is cached for 30 minutes

Prerequisites

• python3-maas-client installed via apt on Ubuntu
• python 3

Installing

The python3-maas-client seems to only be available on Ubuntu.

If you wish to do this on a non-Ubuntu machine, you will have to grab the contents of dpkg -L python3-maas-client from an Ubuntu box and copy it over to your python3 directories.

Usage

This script creates groups based on the first letters of the hostname. e.g. swrmwrk004 and swrmwrk001 will be in group swrmwrk

Run the script with no arguments and you'll see the help prompt

./maasinv.py 

usage: maasinv.py [-h] [--list] [--host HOSTNAME] [--raw] [--raw-host RAWHOST]
