Leverage Puppet facts and PuppetDB to generate a dynamic Ansible inventory

Usage

./puppetdb.py -h
usage: puppetdb.py [-h] (--list | --host HOST)

PuppetDB Inventory Module

optional arguments:
  -h, --help   show this help message and exit
  --refresh    Refreshes cached information
  --list       List servers known by PuppetDB
  --host HOST  List details about specified host

Configuration

See in-file documentation provided in puppetdb.yml

Notes on large(r) amount of hosts in a single PuppetDB instance

If you are dealing with a large(r) amount of hosts in a single PuppetDB instance, what becomes important for improving performance is:

The JSON library to encode and decode data for Ansible to use

The script will automatically attempt to load, in order of performance: ujson > simplejson > json (stdlib). For best results, try to install ujson.

Latency between where you run the inventory script and the PuppetDB instance

Try to run the inventory somewhere with as little latency as you can to your PuppetDB instance.

Performance of the server the inventory is run on
Performance of the PuppetDB server

Usage example

./puppetdb.py --host node.domain.tld
