NAME
----
ansible-modules - stock modules shipped with ansible
DESCRIPTION
-----------
Ansible ships with a number of modules that can be executed directly on remote hosts or through
ansible playbooks.
IDEMPOTENCE
-----------
Most modules other than command are idempotent, meaning they will seek to avoid changes
unless a change needs to be made. When using ansible playbooks, these modules can
trigger change events. Unless otherwise noted, all modules support change hooks.
command
-------
The command module takes the command name followed by a list of arguments, space delimited.
This is the only module that does not use key=value style parameters.
Example usage:
"/sbin/shutdown -t now"
This module does not support change hooks.
Returns the return code from the program as well as timing information.
Async command running and command execution time limits are in plan.
copy
----
The copy module takes a list of source files
*src=*::
Local absolute path to a file to copy to the remote server
*dest=*::
Remote absolute path where the file should end up
This module also returns md5sum information about the resultant file.
facter
------
Runs the discovery program 'facter' on the remote system, returning
JSON data that can be useful for inventory purposes. It makes
no changes on the remote system.
Requires that 'facter' and 'ruby-json' be installed on the remote end.
This module takes no parameters & does not support change hooks.
git
---
Deploys software from git checkouts.
This module is in plan.
ohai
----
Similar to the facter module, this returns JSON inventory data but
makes no changes on the remote system.
Requires that 'ohai' be installed on the remote end.
This module takes no parameters & does not support change hooks.
ping
----
A trivial test module, this module always returns the integer '1' on
successful contact. It makes no changes on the remote system.
This module does not support change hooks.
service
-------
Controls services on remote machines.
*ensure=*::
Values are 'started', 'stopped', or 'restarted'. Started/stopped
are idempotent actions that will not run commands unless neccessary.
'restarted' will always bounce the service
*name=*::
The name of the service
setup
-----
Writes a JSON file containing key/value data, for use in templating.
Call this once before using the template modules, usually as the very
first step in your playbook.
*metadata=*::
Optionally overrides the default JSON file location of /etc/ansible/setup.
If used, also supply the metadata parameter to 'template'.
Does not support change hooks yet, but in plan.
template
--------
Templates a file out to a remote server. Call the setup module prior to usage.
*src=*::
path of a Jinja2 formatted template on the local server
*dest*::
location to render the template on the remote server
*metadata*::
location of a JSON file to use to supply template data. Default is /etc/ansible/setup
which can be easily created using the 'setup' module.
This module also returns md5sum information about the resultant file.
user
----
This module is in plan.
yum
---
This module is in plan.
WRITING YOUR OWN MODULES
------------------------
To write your own modules, simply follow the convention of those already available in
/usr/share/ansible. Modules must return JSON but can be written in any language.
To support change hooks, modules should return hashes, with a changed: True/False
element at the top level. Modules can also choose to indicate a failure scenario
by returning a top level 'failure' element with a True value.
