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
