How to run Filebeat on Kubernetes?
You can use Filebeat Docker images on Kubernetes to retrieve and ship container logs. You deploy Filebeat as a DaemonSet to ensure there’s a running instance on each node of the cluster. Filebeat DaemonSet deployed in Kube-system namespace by default. you can change the namespace by modifying the manifest files.

curl -L -O https://raw.githubusercontent.com/elastic/beats/6.6/deploy/kubernetes/filebeat-kubernetes.yaml
Change the default configuration for Elasticsearch in the manifest file if your Elasticsearch is not running on the default ports and localhost.
- name: ELASTICSEARCH_HOSTvalue: elasticsearch.example.com --> host fqdn or ip- name: ELASTICSEARCH_PORTvalue: "9200"
