What are Ansible Facts

From bib. source

[…] whenever you run an Ansible playbook, Ansible first gathers information (“facts”) about each host in the play.

These facts gathered by Ansible about a server / host include (Geerling 2023, 99):

The public IP address
The CPU type
The disk space
OS information
Network interface information And much more.

One can get a list of all the available information about a server / host using the ansible command with the setup module, e.g. (Ibid):

ansible munin -m setup

Or, put more generally:

ansible $INVENTORY_FILE_GROUP -m setup
