# ======================== 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 see the documentation for further information on configuration options:
|
||
|
|
# <http://www.elastic.co/guide/en/elasticsearch/reference/current/setup-configuration.html>

# ---------------------------------- Cluster -----------------------------------
|
||
|
|
#
|
||
|
|
# Use a descriptive name for your cluster:
|
||
|
|
#
|
||
|
|
cluster.name: {{ elasticsearch_cluster_name }}
|
||
|
|
#
|
||
|
|
# ------------------------------------ Node ------------------------------------
|
||
|
|
#
|
||
|
|
# Use a descriptive name for the node:
|
||
|
|
#
|
||
|
|
node.name: {{ ansible_fqdn }}
|
||
|
|
#
|
||
|
|
# Add custom attributes to the node:
|
||
|
|
#
|
||
|
|
# node.rack: r1
|
||
|
|
#

|

|
#
|

|
|
# Make sure that the `ES_HEAP_SIZE` environment variable is set to about half the memory
|
||
|
|
# available on the system and that the owner of the process is allowed to use this limit.
|
||
|
