Leverage Puppet facts and PuppetDB to generate a dynamic Ansible inventory
./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
See in-file documentation provided in puppetdb.yml
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
