I made an es-deploy.yml file then I typed the path.log and path.data values.
After creating the pod, I checked that directory then there was nothing.
The setting did not work!
How can I edit path.data and path.log for elasticsearch on Kubernetes!
I also tried using PATH_DATA

volumeMounts:
- mountPath: /data/elk/Those values path.data and path.logs are not environment variables. They are config options.
The default path.data for the official elasticsearch image is /usr/share/elasticsearch/data based on the default value of ES_HOME=/usr/share/elasticsearch/ If you don't want to use that path you have to override it in the elasticsearch.yaml config.
You will have to create a ConfigMap containing your elasticsearch.yaml with something like this:
apiVersion: v1
kind: ConfigMap
metadata:
name: elasticsearch-config
namespace: es
data:
elasticsearch.yml: |
cluster:
name: ${CLUSTER_NAME:elasticsearch-default}
node:
master: ${NODE_MASTER:true}
data: ${NODE_DATA:true}
name: ${NODE_NAME}
ingest: ${NODE_INGEST:true}
max_local_storage_nodes: ${MAX_LOCAL_STORAGE_NODES:1}
processors: ${PROCESSORS:1}
network.host: ${NETWORK_HOST:_site_}
path:
data: ${DATA_PATH:"/data/elk"}
repo: ${REPO_LOCATIONS:[]}
bootstrap:
memory_lock: ${MEMORY_LOCK:false}
http:
enabled: ${HTTP_ENABLE:true}
compression: true
cors:
enabled: true
allow-origin: "*"
discovery:
zen:
ping.unicast.hosts: ${DISCOVERY_SERVICE:elasticsearch-discovery}
minimum_master_nodes: ${NUMBER_OF_MASTERS:1}
xpack:
license.self_generated.type: basic(Note that the above ConfigMap will also allow you to use the DATA_PATH environment variable)
Then mount your volumes in your Pod with something like this:
volumeMounts:
- name: storage
mountPath: /data/elk
- name: config-volume
mountPath: /usr/share/elasticsearch/config/elasticsearch.yml
subPath: elasticsearch.yml
volumes:
- name: config-volume
configMap:
name: elasticsearch-config
- name: storage
<add-whatever-volume-you-are-using-for-data>
