<p>I'm deploying ELK on k8s but getting error on <code>Filebeat</code></p>
<p><code>kubectl describe pod filebeat-filebeat-rpjbg -n elk</code> ///</p>
<p><strong>Error:</strong></p>
<pre><code>Warning  Unhealthy  8s (x5 over 48s)  kubelet            Readiness probe failed: logstash: logstash:5044...

</code></pre>
<p>In logstash <code>values.yaml</code> may be this causing error?</p>

Breaking News
<p>Filebeat is trying to resolve &quot;logstash&quot;, but you don't have a service with that name. You have &quot;logstash-logstash&quot;. Try to change filebeat config (line 49 and 116 in filebeat values.yaml) or change the name of your logstash service accordingly.</p>
