<p>I set up an EFK stack for gathering my different k8s pods logs based on <a href="https://mherman.org/blog/logging-in-kubernetes-with-elasticsearch-Kibana-fluentd/" rel="nofollow noreferrer">this tutorial</a> on a Microk8s single node cluster. Everything is up and working and I can connect kibanna to elasticsearch and see the indexes but in the discovery section of kibana there is no log related to my pods and there are kubelete logs.</p>

<p>When I checked the logs of fluentd I saw that it is full of backslashes:</p>

<pre><code>2019-08-05 15:23:17 +0000 [warn]: #0 [in_tail_container_logs] pattern not match: "2019-08-05T17:23:10.167379794+02:00 stdout P 2019-08-05 15:23:10 +0000 [warn]: #0 [in_tail_container_logs] pattern not match: \"2019-08-05T17:23:07.09726655+02:00 stdout P 2019-08-05 15:23:07 +0000 [warn]: #0 [in_tail_container_logs] pattern not match: \\\"2019-08-05T17:23:04.433817307+02:00 stdout P 2019-08-05 15:23:04 +0000 [warn]: #0 [in_tail_container_logs] pattern not match: \\\\\\\"2019-08-05T17:22:52.546188522+02:00 stdout P 2019-08-05 15:22:52 +0000 [warn]: #0 [in_tail_container_logs] pattern not match: \\\\\\\\\\\\\\\"2019-08-05T17:22:46.694679863+02:00 stdout F 
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
</code></pre>

<p>Can someone please tell me what I am doing wrong and where all those backslashes are coming from?</p>

<p>For posterity, I'm going to provide <a href="https://github.com/fluent/fluentd/issues/2407#issuecomment-747488004" rel="nofollow noreferrer">this solution</a>, which seems a lot more straight forward than anything else I've found:</p>
<pre><code>env:
    - name: FLUENT_CONTAINER_TAIL_PARSER_TYPE
      value: /^(?&lt;time&gt;.+) (?&lt;stream&gt;stdout|stderr) [^ ]* (?&lt;log&gt;.*)$/
</code></pre>
<p>Just place that in the env variables underneath your <code>fluentd</code> YAML configuration.</p>
