# ======================== OpenSearch Configuration =========================
|
|
#
|
|
# NOTE: OpenSearch 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.opensearch.org
|
|
# ---------------------------------- Cluster -----------------------------------
|
|
#
|
|
# Use a descriptive name for your cluster:
|
|
#
|
|
cluster.name: {{ opensearch_cluster_name }}
|
|
#
|
|
# ------------------------------------ Node ------------------------------------
|
|
#
|
|
# Use a descriptive name for the node:
|
|
#
|
|
node.name: {{ ansible_fqdn }}
|
|
#
|
|
{% if not opensearch_single_node %}
|
|
cluster.initial_master_nodes:
|
|
{% for n in opensearch_bootstrap_known_masters %}
|
|
- {{ n }}
|
|
{% endfor %}
|
|
|
|
#
|
|
# Add custom attributes to the node:
|
|
#
|
|
# node.rack: r1
|
|
{% endif %}
|
|
#
|
|
# ----------------------------------- Paths ------------------------------------
|
|
#
|
|
# Path to directory where to store the data (separate multiple locations by comma):
|
|
#
|
|
path.data: {% for data_dir in opensearch_data_dirs %}{{ data_dir }}{% if not loop.last %},{% endif %}{% endfor %}
|
|
|
|
#
|
|
# Path to log files:
|
|
#
|
|
path.logs: {{ opensearch_log_dir }}
|
|
#
|
|
# ----------------------------------- 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.
|
|
#
|
|
# OpenSearch performs poorly when the system is swapping the memory.
|
|
#
|
|
# ---------------------------------- Network -----------------------------------
|
|
#
|
|
# Set the bind address to a specific IP (IPv4 or IPv6):
|
|
#
|
|
network.host: {{ opensearch_bind_ip }}
|
|
#
|
|
# Set a custom port for HTTP:
|
|
#
|
|
http.port: {{ opensearch_http_port }}
|
|
|
|
# by default transport.host refers to network.host
|
|
transport.host: {{ opensearch_bind_ip }}
|
|
transport.tcp.port: {{ opensearch_transport_min_port }}-{{ opensearch_transport_max_port }}
|
|
#
|
|
# --------------------------------- Discovery ----------------------------------
|
|
#
|
|

#

|

{% if opensearch_real_cluster %}
