<p>I have a kuberenetes cluster and I am trying to gather logs from the containers in my cluster. I am using Filebeat to collect the logs and send it to elasctic search and then display it in Kibana. I deployed Kibana and elastic search and it works fine. I am using a DaemonSet to deploy FileBeat. 
Here is the YAML file that I am referencing to deploy Filebeat. 
I used the manifest file from here to deploy it and modified it a little.</p>

<p>I checked the pods running Filebeat and it stores the logs. But somehow it doesn't post it to elastic search. What should be my exact configuration to make it post to elasticsearch. I am stuck on it for a couple of days now and I am out of options. Any help would be greatly appreciated.</p>

<p>Your filebeat config is not picking up any input types.</p>

<p>The filebeat.yaml file input path must point to your filebeats-inputs.yaml instead of the logs location.  Which in turn delegates to docker input type.  Default containers.path is /var/lib/docker/containers.</p>
