<p>Often a user of a configuration management system will want to keep inventory
in a different system. Frequent examples include LDAP, <a class="reference external" href="http://cobbler.github.com">Cobbler</a>,
or a piece of expensive enterprisey CMDB software. Ansible easily supports all
of these options via an external interventory system.</p>

<p>If you have a data store system where an Ansible external inventory script doesn&#8217;t already exist, this may require a little coding, but we have a <a class="reference external" href="https://github.com/ansible/ansible/blob/master/examples/scripts/cobbler_external_inventory.py">Cobbler example</a> in the main source tree &#8211; but it&#8217;s pretty simple, as we&#8217;ll explain below &#8211; that would provide a good starting point. Like with modules, it&#8217;s possible to build an external inventory script in any language, as long as it returns JSON.</p>

<p>So that&#8217;s the Cobbler integration support &#8211; using the cobbler script as an example, it should be trivial to adapt Ansible to pull inventory, as well as variable information, from any data source.
