| 53 | <h1>Using reclass<a class="headerlink" href="#using-reclass" title="Permalink to this headline">¶</a></h1> |
| 54 | <p>For information on how to use <strong>reclass</strong> directly, call <tt class="docutils literal"><span class="pre">reclass</span> <span class="pre">--help</span></tt> |
| 55 | and study the output, or have a look at its <a class="reference internal" href="manpage.html"><em>manual page</em></a>.</p> |
| 56 | <p>The three options, <tt class="docutils literal"><span class="pre">--inventory-base-uri</span></tt>, <tt class="docutils literal"><span class="pre">--nodes-uri</span></tt>, and |
| 57 | <tt class="docutils literal"><span class="pre">--classes-uri</span></tt> together specify the location of the inventory. If the base |
| 58 | URI is specified, then it is prepended to the other two URIs, unless they are |
| 59 | absolute URIs. If these two URIs are not specified, they default to <tt class="docutils literal"><span class="pre">nodes</span></tt> |
| 60 | and <tt class="docutils literal"><span class="pre">classes</span></tt>. Therefore, if your inventory is in <tt class="docutils literal"><span class="pre">/etc/reclass/nodes</span></tt> and |
| 61 | <tt class="docutils literal"><span class="pre">/etc/reclass/classes</span></tt>, all you need to specify is the base URI as |
| 62 | <tt class="docutils literal"><span class="pre">/etc/reclass</span></tt> — which is actually the default (specified in |
| 63 | <tt class="docutils literal"><span class="pre">reclass/defaults.py</span></tt>).</p> |
| 64 | <p>If you’ve installed <strong>reclass</strong> from source as per the <a class="reference internal" href="install.html"><em>installation |
| 65 | instructions</em></a>, try to run it from the source directory like this:</p> |
| 66 | <div class="highlight-python"><div class="highlight"><pre>$ reclass -b examples/ --inventory |
| 67 | $ reclass -b examples/ --nodeinfo localhost |
| 68 | </pre></div> |
| 69 | </div> |
| 70 | <p>This will make it use the data from <tt class="docutils literal"><span class="pre">examples/nodes</span></tt> and |
| 71 | <tt class="docutils literal"><span class="pre">examples/classes</span></tt>, and you can surely make your own way from here.</p> |
| 72 | <p>On Debian-systems, use the following:</p> |
| 73 | <div class="highlight-python"><div class="highlight"><pre>$ reclass -b /usr/share/doc/reclass/examples/ --inventory |
| 74 | $ reclass -b /usr/share/doc/reclass/examples/ --nodeinfo localhost |
| 75 | </pre></div> |
| 76 | </div> |
| 77 | <p>More commonly, however, use of <strong>reclass</strong> will happen indirectly, and through |
| 78 | so-called adapters. The job of an adapter is to translate between different |
| 79 | invocation paradigms, provide a sane set of default options, and massage the |
| 80 | data from <strong>reclass</strong> into the format expected by the automation tool in use. |
| 81 | Please have a look at the respective README files for these adapters, i.e. |
| 82 | for <a class="reference internal" href="salt.html"><em>Salt</em></a>, for <a class="reference internal" href="ansible.html"><em>Ansible</em></a>, and for <a class="reference internal" href="puppet.html"><em>Puppet</em></a>.</p> |
