|
<p>cdist supports triggering for host installation/configuration using trigger command.
|
|
This command starts trigger server at management node, for example:</p>
|
|
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>$ cdist trigger -b -v
|
|
</pre></div>
|
|
</div>
|
|
<p>This will start cdist trigger server in verbose mode. cdist trigger server accepts
|
|
simple requests for configuration and for installation:</p>
|
|
<ul class="simple">
|
|
<li><strong>/cdist/install/.*</strong> for installation</li>
|
|
<li><strong>/cdist/config/.*</strong> for configuration.</li>
|
|
</ul>
|
|
<p>Machines can then trigger cdist trigger server with appropriate requests.
|
|
If the request is, for example, for installation (<strong>/cdist/install/</strong>)
|
|
then cdist trigger server will start install command for the client host using
|
|
parameters specified at trigger server startup. For the above example that means
|
|
that client will be installed using default initial manifest.</p>
|
|
<p>When triggered cdist will try to reverse DNS lookup for host name and if
|
|
host name is dervied then it is used for running cdist config. If no
|
|
host name is resolved then IP address is used.</p>
|
|
<p>This command returns the following response codes to client requests:</p>
|
|
<ul class="simple">
|
|
<li>200 for success</li>
|
|
<li>599 for cdist run errors</li>
|
|
<li>500 for cdist/server errors.</li>
|
|
</ul>
