# ======================== Elasticsearch Configuration =========================

#

# NOTE: Elasticsearch comes with reasonable defaults for most settings.

#       Before you set out to tweak and tune the configuration, make sure you

#       understand what are you trying to accomplish and the consequences.

#

# The primary way of configuring a node is via this file. This template lists

# the most important settings you may want to configure for a production cluster.

#

# Please consult the documentation for further information on configuration options:

# https://www.elastic.co/guide/en/elasticsearch/reference/index.html

#

# ---------------------------------- Cluster -----------------------------------

#

# Use a descriptive name for your cluster:

#

#cluster.name: my-application

#

# ------------------------------------ Node ------------------------------------

#

# Use a descriptive name for the node:

#

#node.name: node-1

#

# Add custom attributes to the node:

#

#node.attr.rack: r1

#

# ----------------------------------- Paths ------------------------------------

#

# Path to directory where to store the data (separate multiple locations by comma):

#

#path.data: /path/to/data

#

# Path to log files:

#

#path.logs: /path/to/logs

#

# ----------------------------------- Memory -----------------------------------

#

# Lock the memory on startup:

#

#bootstrap.memory_lock: true

#

# Make sure that the heap size is set to about half the memory available

# on the system and that the owner of the process is allowed to use this

# limit.

#

# Elasticsearch performs poorly when the system is swapping the memory.

#

# ---------------------------------- Network -----------------------------------

#

# By default Elasticsearch is only accessible on localhost. Set a different

# address here to expose this node on the network:

#

#network.host: 192.168.0.1

#

# By default Elasticsearch listens for HTTP traffic on the first free port it

# finds starting at 9200. Set a specific HTTP port here:

#

http.port: 9200

#

# For more information, consult the network module documentation.

#

# --------------------------------- Discovery ----------------------------------

#

# Pass an initial list of hosts to perform discovery when this node is started:

# The default list of hosts is ["127.0.0.1", "[::1]"]

#

#discovery.seed_hosts: ["host1", "host2"]

#

# Bootstrap the cluster using an initial set of master-eligible nodes:

#

#cluster.initial_master_nodes: ["node-1", "node-2"]

#

# For more information, consult the discovery and cluster formation module documentation.

#

# --------------------------------- Readiness ----------------------------------

#

# Enable an unauthenticated TCP readiness endpoint on localhost

#

#readiness.port: 9399

#

# ---------------------------------- Various -----------------------------------

#

# Allow wildcard deletion of indices:

#

#action.destructive_requires_name: false

http.cors.enabled: true

http.cors.allow-origin: "*"

#----------------------- BEGIN SECURITY AUTO CONFIGURATION -----------------------

#

# The following settings, TLS certificates, and keys have been automatically

# generated to configure Elasticsearch security features on 15-07-2022 05:45:57

#

# --------------------------------------------------------------------------------

# Enable security features

xpack.security.enabled: false

xpack.security.enrollment.enabled: true

# Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents

xpack.security.http.ssl:

enabled: true

keystore.path: certs/http.p12

# Enable encryption and mutual authentication between cluster nodes

xpack.security.transport.ssl:

enabled: true

verification_mode: certificate

keystore.path: certs/transport.p12

truststore.path: certs/transport.p12

# Create a new cluster with the current node only

# Additional nodes can still join the cluster later

# Allow HTTP API connections from anywhere

# Connections are encrypted and require user authentication

http.host: 127.0.0.1

# Allow other nodes to join the cluster from anywhere

# Connections are encrypted and mutually authenticated

#transport.host: 0.0.0.0

#----------------------- END SECURITY AUTO CONFIGURATION -------------------------
