Synopsis

ansible <host-pattern> [-m module_name] [-a args] [options]

Description

Ansible is an extra-simple tool/framework/API for doing 'remote things'. This is the adhoc command that allows for a 'single task playbook' run.

Arguments

host-pattern

A name of a group in the inventory, a shell-like glob selecting hosts in inventory or any combination of the two separated by commas.

Prompt for the connection password, if it is needed for the transport used. For example, using ssh and not having a key-based authentication with ssh-agent.

Inventory

Ansible stores the hosts it can potentially operate on in an inventory. This can be an ini-like file, a script, directory or a list. The ini syntax is one host per line. Groups headers are allowed and are included on their own line, enclosed in square brackets that start the line.

Ranges of hosts are also supported. For more information and additional options, see the documentation on http://docs.ansible.com/.

Environment

The following environment variables may be specified.

ANSIBLE_INVENTORY — Override the default ansible inventory file

ANSIBLE_LIBRARY — Override the default ansible module library path

ANSIBLE_CONFIG — Override the default ansible config file

Many more are available for most options in ansible.cfg

Files

/etc/ansible/hosts — Default inventory file

/usr/share/ansible/ — Default module library

/etc/ansible/ansible.cfg — Config file, used if present

~/.ansible.cfg — User config file, overrides the default config if present
