<p>cdist comes with simple built-in tag based inventory. It is a simple inventory
with list of hosts and a host has a list of tags.
Inventory functionality is still in <strong>beta</strong> so it can be used only if beta
command line flag is specified (-b, --beta) or setting CDIST_BETA env var.</p>
</div>
<div class="section" id="description">
<h2><span class="section-number">20.2. </span>Description<a class="headerlink" href="#description" title="Permalink to this headline"></a></h2>
<p>The idea is to have simple tagging inventory. There is a list of hosts and for
each host there are tags. Inventory database is a set of files under inventory
database base directory. Filename equals hostname. Each file contains tags for
hostname with each tag on its own line.</p>
<p>Using inventory you can now configure hosts by selecting them by tags.</p>
<p>Tags have no values, as tags are just tags. Tag name-value would in this
context mean that host has two tags and it is selected by specifying that both
tags are present.</p>
<p>This inventory is <strong>KISS</strong> cdist built-in inventory database. You can maintain it
using cdist inventory interface or using standard UNIX tools.</p>

<h2><span class="section-number">20.3. </span>cdist inventory interface<a class="headerlink" href="#cdist-inventory-interface" title="Permalink to this headline"></a></h2>
<p>With cdist inventory interface you can list host(s) and tag(s), add host(s),
add tag(s), delete host(s) and delete tag(s).</p>

<p>config command now has new options, <strong>-t</strong>, <strong>-a</strong> and <strong>-A</strong>.</p>
<p><strong>-A</strong> means that all hosts in tag db is selected.</p>
<p><strong>-a</strong> means that selected hosts must contain ALL specified tags.</p>
<p><strong>-t</strong> means that host specifies tag - all hosts that have specified tags are
selected.</p>

<p>cdist can be used with any external inventory where external inventory is
some storage or database from which you can get a list of hosts to configure.
cdist can then be fed with this list of hosts through stdin or file using
<strong>-f</strong> option. For example, if your host list is stored in sqlite3 database
hosts.db and you want to select hosts which purpose is <strong>django</strong> then you
can use it with cdist like:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>$ sqlite3 hosts.db <span class="s2">&quot;select hostname from hosts where purpose = &#39;django&#39;;&quot;</span> <span class="p">|</span> cdist config
