# ======================== 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: {{ elasticsearch_cluster_name }} cluster.name: {{ elasticsearch_cluster_name }}
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: {{ elasticsearch_node_name }} node.name: {{ elasticsearch_node_name }}
#
# 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: /var/lib/elasticsearch path.data: /var/lib/elasticsearch
#
# Path to log files:
#
path.logs: /var/log/elasticsearch path.logs: /var/log/elasticsearch
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
bootstrap.memory_lock: true 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 -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: {{ elasticsearch_network_host }} network.host: {{ elasticsearch_network_host }}
#
# Set a custom port for HTTP: {% if single_node %}
# discovery.type: single-node
#http.port: 9200 {% elif elasticsearch_bootstrap_node %}
# cluster.initial_master_nodes:
# For more information, consult the network module documentation. {% for item in elasticsearch_cluster_nodes %}
# - {{ item }}
# --------------------------------- Discovery ---------------------------------- {% endfor %}
# {% elif elasticsearch_master_candidate %}
# Pass an initial list of hosts to perform discovery when new node is started: discovery.seed_hosts:
# The default list of hosts is ["127.0.0.1", "[::1]"] {% for item in elasticsearch_cluster_nodes %}
# - {{ item }}
#discovery.zen.ping.unicast.hosts: ["host1", "host2"] {% endfor %}
# {% endif %}
# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
#
#discovery.zen.minimum_master_nodes: 3
#
# For more information, consult the zen discovery module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true
