module: setup
short_description: Gathers facts about remote hosts
options:
filter:
version_added: "1.1"
description:
- if supplied, only return facts that match this shell-style (fnmatch) wildcard.
required: false
default: '*'
description:
- 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 C(/usr/bin/ansible) to check what variables are
available to a host. Ansible provides many I(facts) about the system,
automatically.
notes:
- More ansible facts will be added with successive releases. If I(facter) or
I(ohai) are installed, variables from these programs will also be snapshotted
into the JSON file for usage in templating. These variables are prefixed
with C(facter_) and C(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 I(facter) and I(ohai) means you can avoid Ruby-dependencies on your
remote systems. (See also M(facter) and M(ohai).)
- The filter option filters only the first level subkey below ansible_facts.
