.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\&. 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\&. These will probably be special keyvalue parameters expressed on the end of the command line, like ANSTIMEOUT=1 and ANS_ASYNC=1 or similar\&.
|
||
|
|
.SH "COPY"
|
||
|
|
.sp
|
||
|
|
The copy module takes a list of source files
|
||
|
|
.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
|

.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\&.

|
||
|
|
\fIrestarted\fR
|
||
|
|
will always bounce the service

||
|
|
\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
|
||
|
|
.SH "TEMPLATE"
|
||
|
|
.sp
|

|

.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\&.
