ansible-maas-inventory

A inventory generator script to work with Ubuntu MAAS. It will generate your groups by looking at either the tags or hostname prefix you have in your MAAS nodes.

Requirements

• Python3

Example

By looking at the tests it's quite easy to understand how it works. Just look at the fixtures file test_fixtures.py.

Set environment variables for MAAS_API_URL and MAAS_API_KEY. After that you can run

   $ python maas.py --list

and with ansible

    $ ansible -i maas.py some-playbook.yml

Output

Configuration

Configuration can be done by editing the maas.ini file or defining a new environment variable MAAS_INI_PATH indicating a new configuration file.

Available configuration:

[maas]
group_machines_by = tags | hostnames

[auth]
maas_api_key = XXXX:XXXX:XXXX
maas_api_url = https://docs.maas.io/MAAS/api/2.0/

[cache]
cache_path = ~/.ansible/tmp
cache_max_age = 300
