Metricbeat modules.d as hostpath

[Pavan_Kumar2 (Pavan Kumar)]

Hi,

I new to elastic beats. I have a question regarding metricbeat.. Whenever I try to use hostpath for modules.d for metricbeat, the data in modules.d in pod gets removed and replaced by nothing (modules.d folder becomes empty)..

apiVersion: extensions/v1beta1
kind: DaemonSet
metadata:
name: metricbeat
spec:
selector:
matchLabels:
name: metricbeat
template:
metadata:
labels:
name: metricbeat
spec:
nodeSelector:
zone: default
containers:

• image: metricbeat image
  name: metricbeat
  env:
• name: ES_HOST
  value: elasticsearch
• name: ES_PORT
  value: "9200"
  resources: {}
  terminationMessagePath: /dev/termination-log
  volumeMounts:
• mountPath: /usr/share/metricbeat/modules.d #this becomes empty
  name: metricbeat-modules-claim
  readOnly: true
  serviceAccount: default
  terminationGracePeriodSeconds: 10
  volumes:
• name: metricbeat-modules-claim
  hostPath:
  path: /opt/metricbeat-modules

If I remove the volumes and volumeMounts the data in the pod in directory (/usr/share/metricbeat/modules.d) has the data that I put while creating docker image..

Can someone help me how to use hostPath for modules.d? All examples are showing using configMap for modules.d..

Thanks
