A callback plugin and a custom inventory script used to store and fetch ansible fact data in Redis.
- A running redis instance
- Copy inventory.py to lib/ansible/callback_plugins
- Copy facts_to_groups.py to /etc/ansible/hosts/ or just use it as your inventory script.
When installed, run ansible -m setup all to collect all facts to the cache. When the cache is populated, you can start doing some interesting ad-hoc commands:
ansible -m shell -a "yum -y upgrade" "ansible_os_family_RedHat:&ansible_distribution_version_6.0"
Or use them in your playbooks:
- hosts: ansible_system_OpenBSD
tasks:
- debug: msg="Wow, this machine is awesome"
Only simple facts are stored, no hashes or lists.
