This module is automatically called by playbooks to gather useful variables about remote hosts that can be used
|
|
|
|
|
in playbooks. It can also be executed directly by /usr/bin/ansible to check what variables are available
|
|
|
|
|
to a host.
|
|
|
|
|
|
|
|
|
|
Ansible provides many 'facts' about the system, automatically.
|
|
|
|
|
|
|
|
|
|
Some of the variables that are supplied are listed below. These in particular
|
|
|
|
|
are from a VMWare Fusion 4 VM running CentOS 6.2::

More ansible facts will be added with successive releases.
|
|
|
|
|
|
|
|
|
|
If facter or ohai are installed, variables from these programs will
|
|
|
|
|
also be snapshotted into the JSON file for usage in templating. These
|
|
|
|
|
variables are prefixed with ``facter_`` and ``ohai_`` so it's easy to
|
|
|
|
|
tell their source.
|
|
|
|
|
|
|
|
|
|
All variables are bubbled up to the caller. Using the ansible facts and choosing
|
|
|
|
|
to not install facter and ohai means you can avoid ruby-dependencies
|
|
|
|
|
on your remote systems.

Example action from `/usr/bin/ansible`::
