<h2>Module Provided ‘Facts’<a class="headerlink" href="#module-provided-facts" title="Permalink to this headline">¶</a></h2>
|
||||
<p>The ‘setup’ module that ships with Ansible provides many variables about a system that can be used in playbooks
|
||||
and templates. However, it’s possible to also add your own facts without modifying the system module. To do
|
||||
this, just have the module return a <cite>ansible_facts</cite> key, like so, along with other return data. This requires
|
||||
Ansible 0.4 and later:</p>
|
||||
<div class="highlight-python"><pre>{
|
||||
"changed" : True,
|
||||
"rc" : 5,
|
||||
"ansible_facts" : {
|
||||
"leptons" : 5000
|
||||
"colors" : {
|
||||
"red" : "FF0000",
|
||||
"white" : "FFFFFF"
|
||||
}
|
||||
}
|
||||
}</pre>
|
||||
</div>
|
||||
<p>These ‘facts’ will be available to all statements called after that module (but not before) in the playbook.
|
||||
A good idea might be make a module called ‘site_facts’ and always call it at the top of each playbook, though
|
||||
we’re always open to improving the selection of core facts in Ansible as well.</p>

This module is new in Ansible 0.4.</p>
|

<p>This is useful and should only be done in two cases. The first case is installing
|
||||
python-simplejson on older (python 2.4 and before) hosts that need it as a dependency
|
||||
to run modules, since nearly all core modules require it. Another is speaking to any
|

devices such as routers that do not have any Python installed. In any other case,
|

using the ‘shell’ or ‘command’ module is much more appropriate.</p>
|

<p>Arguments given to ‘raw’ are run directly through the configured remote shell and
|

only output is returned. There is no error detection or change handler support
|
||||
for this module.</p>
