<p>I have deployed my application image into Kubernetes.</p>
<p>I am trying to send application logs to Splunk. One option would be to use DeamonSet. But, due to some restrictions, I would like to use sidecar.</p>
<p>Is there any sidecar for sending logs from Kubernetes Docker to Splunk?</p>

<p>As you say, you could add a docker container to your pod with a shared volume, for example</p>

<pre><code>apiVersion: v1
kind: Pod
metadata:
  name: app-with-sidecar-logs
spec:
  volumes:
  - name: logs
    emptyDir: {}
  containers:
  - name: app
    image: nginx
    volumeMounts:
    - name: logs
      mountPath: /var/logs
  - name: fluentd
    image: fluent/fluentd
    volumeMounts:
    - name: logs
      mountPath: /var/logs
</code></pre>

<p>You could use the splunk plugin for fluentd configuring and running the docker container properly.</p>

<pre><code>&lt;match pattern&gt;
  type splunk
  host &lt;splunk_host&gt;
  port &lt;splunk_port&gt;
&lt;/match&gt;
</code></pre>
