<p>I am using fluent-bit version 1.4.6 and I am trying to collect logs from a tomcat/logs folder, but I receive:</p>
<p><code>[error] [input:tail:tail.0] read error, check permissions</code>
These files inside the logs folder are all &quot;rw-r-----&quot; (640).</p>
<p>I tried to confirm whether it can read it at all by changing the permissions of a file inside the logs folder and it works, but that does not solve the overall problem.</p>
<p>My question is, is this something that should be set on the tomcat level or it can be done via fluent-bit? Can I start that as a different user?</p>
<p>Thanks in advance!</p>

<p>You didn't specify 👀 how you deployed fluent-bit.</p>
<p>But yes you can run it as a different user specifying a <a href="https://kubernetes.io/docs/tasks/configure-pod-container/security-context/" rel="nofollow noreferrer">SecurityContext</a> in Kubernetes.</p>
<p>For example:</p>
<pre class="lang-yaml prettyprint-override"><code>apiVersion: apps/v1
kind: DaemonSet
metadata:
  name: fluent-bit
  namespace: logging
  labels:
    k8s-app: fluent-bit-logging

      annotations:
