.SH "NAME"
ansible-modules \- stock modules shipped with ansible
.SH "DESCRIPTION"
.sp
Ansible ships with a number of modules that can be executed directly on remote hosts or through ansible playbooks\&.
.SH "IDEMPOTENCE"
.sp
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, as described in ansible\-playbooks (5)\&.
.sp
Unless otherwise noted, all modules support change hooks\&.
.SH "COMMAND"
.sp
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\&.
.PP
Example usage
.RS 4
/sbin/shutdown \-t now
.RE
.sp
This module does not support change hooks\&.
.sp
Returns the return code from the program as well as timing information\&.
.sp
(Async command running and command execution time limits are in plan\&.)
.SH "COPY"
.sp
The copy module moves a file on the local box to remote locations\&.
.PP
\fBsrc=\fR
.RS 4
Local absolute path to a file to copy to the remote server
.RE
.PP
\fBdest=\fR
.RS 4
Remote absolute path where the file should end up
.RE
.sp
This module also returns md5sum information about the resultant file\&.
.SH "FACTER"
.sp
Runs the discovery program \fIfacter\fR on the remote system, returning JSON data that can be useful for inventory purposes\&.
.sp
Requires that \fIfacter\fR and \fIruby\-json\fR be installed on the remote end\&.
.sp
This module is informative only \- it takes no parameters & does not support change hooks, nor does it make any changes on the system\&.
.SH "FILE"
.sp
Ensures the ownership and permissions of files are as desired\&.
.sp
Use copy or template first if you need to make sure a file is on the box\&.
.sp
In plan\&.
.SH "GIT"
.sp
Deploys software from git checkouts\&.
.PP
\fBrepo=\fR
.RS 4
git or http protocol address of the repo to checkout
.RE
.PP
\fBdest=\fR
.RS 4
where to check it out, an absolute directory path
.RE
.PP
\fBversion=\fR
.RS 4
what version to check out \(em either the git SHA, the literal string
\fIHEAD\fR, or a tag name
.RE
.SH "OHAI"
.sp
Similar to the facter module, this returns JSON inventory data\&. Ohai data is a bit more verbose and nested than facter\&.
.sp
Requires that \fIohai\fR be installed on the remote end\&.
.sp
This module is information only \- it takes no parameters & does not support change hooks, nor does it make any changes on the system\&.
.SH "PING"
.sp
A trivial test module, this module always returns the integer \fI1\fR on successful contact\&.
.sp
This module does not support change hooks\&.
.sp
This module is informative only \- it takes no parameters & does not support change hooks, nor does it make any changes on the system\&.
.SH "SERVICE"
.sp
Controls services on remote machines\&.
.PP
\fBstate=\fR
.RS 4
Values are
\fIstarted\fR,
\fIstopped\fR, or
\fIrestarted\fR\&. Started/stopped are idempotent actions that will not run commands unless neccessary\&.
\fIrestarted\fR
will always bounce the service
.RE
.PP
\fBname=\fR
.RS 4
The name of the service
.RE
.SH "SETUP"
.sp
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\&.
.sp
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 \fIfacter_\fR and \'ohai_" so it\(cqs easy to tell their source\&.
.PP
\fBmetadata=\fR
.RS 4
Optionally overrides the default JSON file location of /etc/ansible/setup\&. If used, also supply the metadata parameter to
\fItemplate\fR\&. Change if running as a non\-root remote user who does not have permissions on /etc/ansible\&.
.RE
.PP
\fBanything=\fR
.RS 4
any other parameters can be named basically anything, and set a key=value pair in the JSON file for use in templating\&.
.RE
.SH "TEMPLATE"
.sp
Templates a file out to a remote server\&. Call the setup module prior to usage\&.
.PP
\fBsrc=\fR
.RS 4
path of a Jinja2 formatted template on the local server
.RE
.PP
\fBdest\fR
.RS 4
location to render the template on the remote server
.RE
.PP
\fBmetadata\fR
.RS 4
location of a JSON file to use to supply template data\&. Default is /etc/ansible/setup which is the same as the default for the setup module\&. Change if running as a non\-root remote user who does not have permissions on /etc/ansible\&.
.RE
.sp
This module also returns md5sum information about the resultant file\&.
.SH "USER"
.sp
This module is in plan\&.
.SH "YUM"
.sp
This module is in plan\&.
.SH "WRITING YOUR OWN MODULES"
.sp
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 \fIfailure\fR element with a True value\&.
.SH "AUTHOR"
.sp
Ansible was originally written by Michael DeHaan\&. See the AUTHORS file for a complete list of contributors\&.
.SH "SEE ALSO"
.sp
