There are 4 kubernetes Services in the cluster:
-es-data ClusterIP None <none> 9200/TCP 22h
-es-http ClusterIP 172.20.88.236 <none> 9200/TCP 22h
-es-internal-http ClusterIP 172.20.255.73 <none> 9200/TCP 22h
-es-master ClusterIP None <none> 9200/TCP 22h
What are the use cases for them? Which one should be used for EFK logging? Which one should I use to add / update the _template?
