Tasks are run against target servers. Some Ansible documentation refers to the target servers as "hosts".



After a clean install of Ansible, the default hosts file is /etc/ansible/hosts. The default hosts file is completely commented out. If you were to issue command ansible all -m ping, the following would be displayed.

[WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match 'all'


Ansible uses inventory plugins to parse inventory. For example, ansible.cfg may have the following.

enable_plugins = host_list, yaml, ini
