Pyventory

Ansible Inventory implementation that uses Python syntax

Install

pip3 install pyventory

Features

• Modular inventory.
• Assests inheritance using Python classes.
• Support for multiple inheritance.
• Support for mixins.
• Support for vars templating using Python string formatting.
• Python 3 (>=3.6) support.
• Python 2 is not supported.

Usage

Create hosts.py and make it executable.

A short example of the hosts.py contents:

#!/usr/bin/env python3
from pyventory import Asset, ansible_inventory

class All(Asset):
    run_tests = False
    use_redis = False
    redis_host = 'localhost'
    minify = False
    version = 'develop'

class Staging(All):
    run_tests = True

staging = Staging()

ansible_inventory(locals())

Consider a more complex example which passes the following json output to Ansible.

Run Ansible playbook with the -i hosts.py key:

ansible-playbook -i hosts.py site.yml

Notice that you need to have your inventory package in PYTHONPATH.
