Ansible Custom Facts
I like Ansible. It’s not perfect but nothing is. Recently I was playing around with the tinc vpn system and wanted a way to set a custom fact per virtual machine based on the vms public ip address. I figured the best way to do that would be to setup a custom fact. It turns out there isn’t that much documentation on just how to do that, or I simply can’t find it. So I’m going to describe what I did in order to setup and use a custom fact.

GitHub - fboender/ansible-cmdb: Generate host overview from ansible fact gathering output
Ansible-cmdb takes the output of Ansible's fact gathering and converts it into a static HTML overview page containing system configuration information.

It supports multiple types of output (html, csv, sql, etc) and extending information gathered by Ansible with custom data. For each host it also shows the groups, host variables, custom variables and machine-local facts.

Jan-Piet Mens :: Caching facts in Ansible
One of the first steps in an Ansible playbook run (unless you explicitly disable it) is the gathering of facts via the setup module. These facts are collected on each machine and were kept in memory for the duration of the playbook run before being destroyed. This meant, that a task wanting to reference a host variable from a different machine would have to talk to that machine at least once in the playbook in order for Ansible to have access to its facts, which in turn sometimes means talking to hosts although we just need a teeny weeny bit of information from that host.

One interesting feature of Ansible version 1.8 is called “fact caching”. It allows us to build a cache of all facts for all hosts Ansible talks to. This cache will be populated with all facts for hosts for which the setup module (i.e. gather_facts) runs. Optional expiry of cached entries as well as enabling the cache itself is controlled by settings in ansible.cfg:

fact_caching = redis
fact_caching_timeout = 3600
fact_caching_connection = localhost:6379:0

By default, fact_caching is set to memory. Configuring it as above, makes Ansible use a Redis instance (on the local machine) as its cache. The timeout specifies when individual Redis keys (i.e. facts on a per/machine basis) will expire. Setting this value to 0 effectively disables expiry, and a positive value is a TTL in seconds.
