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. notes: > 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. examples: - code: ansible all -m setup -tree /tmp/facts description: Obtain facts from all hosts and store them indexed by hostname at /tmp/facts.
