+# ======================== 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 -----------------------------------
+#
+# Name of the Elasticsearch cluster.
+# A node can only join a cluster when it shares its cluster.name with all the other nodes in the cluster. 
+# The default name is elasticsearch, but you should change it to an appropriate name which describes the 
+# purpose of the cluster. 
+#
+cluster.name: $cluster.name
+#
+# ------------------------------------ Node ------------------------------------
+#
+# It is better to provide different meaningfull names fot different elastic nodes.
+# By default, Elasticsearch will take the 7 first character of the randomly generated uuid used as the node id. 
+# Note that the node id is persisted and does not change when a node restarts
+#
+#node.name: $node.name
+#
+#
+# ----------------------------------- Paths ------------------------------------
+#
+# The location of the data files of each index / shard allocated on the node. Can hold multiple locations separated by coma.
+# In production, we should not keep this fixed, as on upgrading Elasticsearch, directory structure 
+# may change & can deal to data loss.
+path.data: /usr/share/elasticsearch/data
+#
+# Elasticsearch's log files location. In production, we should not keep this default to "/elasticsearch/logs", 
+# as on upgrading Elasticsearch, directory structure may change.
+path.logs: /usr/share/elasticsearch/logs
+#
+# ----------------------------------- Memory -----------------------------------
+#
+# It is vitally important to the health of your node that none of the JVM is ever swapped out to disk. 
+# 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 -----------------------------------
+# This IP is published for TCP & HTTP communications.
+# HTTP is used for REST communications.
+# TCP is used for communication between Elasticsearch cluster nodes
+# If you have different different IPs for TCP & HTTP, you have to declare "transport.publish_host" & "http.publish_host"
+# More info: https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html
+network.publish_host: $network.publish_host
+#
+# Set the bind address to a specific IP (IPv4 or IPv6):
+# In order to communicate and to form a cluster with nodes on other servers, your node will need to bind to a 
+# non-loopback address. 
+#network.host: "0.0.0.0"  
+#
+# Set a custom port for HTTP: If required, default is 9200-9300
+# This is used for REST APIs
+http.port: $http.port
+#
+# Port to bind for communication between nodes. Accepts a single value or a range. 
+# If a range is specified, the node will bind to the first available port in the range.
+# Defaults to 9300-9400.
+# More info: 
+transport.tcp.port: $transport.tcp.port
+#
+# For more information, consult the network module documentation.
+#
+# --------------------------------- Discovery ----------------------------------
+#
+# Pass an initial list of hosts to perform discovery when new node is started:
+# To form a cluster with nodes on other servers, you have to provide a seed list of other nodes in the cluster 
+# that are likely to be live and contactable. 
+# By default, Elasticsearch will bind to the available loopback addresses and will scan ports 9300 to 9305 to try 
+# to connect to other nodes running on the same server.
+#
+discovery.zen.ping.unicast.hosts: $discovery.zen.ping.unicast.hosts
+#
+# This setting tells Elasticsearch to not elect a master unless there are enough master-eligible nodes  
+# available. Only then will an election take place.
+# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
+discovery.zen.minimum_master_nodes: 2
+#
+# For more information, consult the zen discovery module documentation.
