 ##################### Elasticsearch Configuration Example #####################

 # This file contains an overview of various configuration settings,
 # targeted at operations staff. Application developers should
 # consult the guide at <http://elasticsearch.org/guide>.
 #
 # The installation procedure is covered at
 # <http://elasticsearch.org/guide/en/elasticsearch/reference/current/setup.html>.
 #
 # Elasticsearch comes with reasonable defaults for most settings,
 # so you can try it out without bothering with configuration.
 #
 # Most of the time, these defaults are just fine for running a production
 # cluster. If you're fine-tuning your cluster, or wondering about the
 # effect of certain configuration option, please _do ask_ on the
 # mailing list or IRC channel [http://elasticsearch.org/community].

 # Any element in the configuration can be replaced with environment variables
 # by placing them in ${...} notation. For example:
 #
 # node.rack: ${RACK_ENV_VAR}

 # For information on supported formats and syntax for the config file, see
 # <http://elasticsearch.org/guide/en/elasticsearch/reference/current/setup-configuration.html>
 ################################### Cluster ###################################

 # Cluster name identifies your cluster for auto-discovery. If you're running
 # multiple clusters on the same network, make sure you're using unique names.
 #
 # cluster.name: elasticsearch

 cluster.name: ES_AAI

 #################################### Node #####################################

 node.name: ES_ONAP
 node.master: true
 node.data: true


 # Use the Cluster Health API [http://localhost:9200/_cluster/health], the
 # Node Info API [http://localhost:9200/_nodes] or GUI tools
 # such as <http://www.elasticsearch.org/overview/marvel/>,
 # <http://github.com/karmi/elasticsearch-paramedic>,
 # <http://github.com/lukas-vlcek/bigdesk> and
 # <http://mobz.github.com/elasticsearch-head> to inspect the cluster state.

 # By default, multiple nodes are allowed to start from the same installation location
 # to disable it, set the following:

 node.max_local_storage_nodes: 1


 #################################### Index ####################################
 # You can set a number of options (such as shard/replica options, mapping
 # or analyzer definitions, translog settings, ...) for indices globally,
 # in this file.
 #
 # Note, that it makes more sense to configure index settings specifically for
 # a certain index, either when creating it or by using the index templates API.
 #
 # See <http://elasticsearch.org/guide/en/elasticsearch/reference/current/index-modules.html> and
 # <http://elasticsearch.org/guide/en/elasticsearch/reference/current/indices-create-index.html>
 # for more information.

 # Set the number of shards (splits) of an index (5 by default):

 index.number_of_shards: 5

 # Set the number of replicas (additional copies) of an index (1 by default):

 index.number_of_replicas: 1

 # These settings directly affect the performance of index and search operations
 # in your cluster. Assuming you have enough machines to hold shards and
 # replicas, the rule of thumb is:
 #
 # 1. Having more *shards* enhances the _indexing_ performance and allows to
 #    _distribute_ a big index across machines.
 # 2. Having more *replicas* enhances the _search_ performance and improves the
 #    cluster _availability_.
 #
 # The "number_of_shards" is a one-time setting for an index.
 #
 # The "number_of_replicas" can be increased or decreased anytime,
 # by using the Index Update Settings API.
 #
 # Elasticsearch takes care about load balancing, relocating, gathering the
 # results from nodes, etc. Experiment with different settings to fine-tune
 # your setup.

 # Use the Index Status API (<http://localhost:9200/A/_status>) to inspect
 # the index status.


 #################################### Paths ####################################

 # Path to directory containing configuration (this file and logging.yml):
 #path.conf: /opt/app/elasticsearch/config

 # Path to directory where to store index data allocated for this node.
 # Use swm auto link to redirect the data directory if necessary.

 #path.data: /opt/app/elasticsearch/data

 # path.data: /path/to/data1,/path/to/data2

 # path.work: /path/to/work

 #path.logs: /opt/app/elasticsearch/logs

 #path.plugins: /opt/app/elasticsearch/plugins


 #################################### Plugin ###################################

 # If a plugin listed here is not installed for current node, the node will not start.
 #
 # plugin.mandatory: mapper-attachments,lang-groovy


 ################################### Memory ####################################

 # Elasticsearch performs poorly when JVM starts swapping: you should ensure that
 # it _never_ swaps.
 #
 # Set this property to true to lock the memory: default is true

 bootstrap.mlockall: true

 # Make sure that the ES_MIN_MEM and ES_MAX_MEM environment variables are set
 # to the same value, and that the machine has enough memory to allocate
 # for Elasticsearch, leaving enough memory for the operating system itself.
 #
 # You should also make sure that the Elasticsearch process is allowed to lock
 # the memory, eg. by using `ulimit -l unlimited`.


 ############################## Network And HTTP ###############################
 # Elasticsearch, by default, binds itself to the 0.0.0.0 address, and listens
 # on port [9200-9300] for HTTP traffic and on port [9300-9400] for node-to-node
 # communication. (the range means that if the port is busy, it will automatically
 # try the next port).

 # Set the bind address specifically (IPv4 or IPv6):
 network.bind_host: 0.0.0.0

 # Set the address other nodes will use to communicate with this node. If not
 # set, it is automatically derived. It must point to an actual IP address.

 # network.publish_host: 0.0.0.0

 # Set both 'bind_host' and 'publish_host':
 # network.host: 192.168.0.1


 # Set a custom port for the node to node communication (9300 by default):
 transport.tcp.port: {{ .Values.config.tcpPort }}

 # Enable compression for all communication between nodes (disabled by default):
 transport.tcp.compress: false

 # Set a custom port to listen for HTTP traffic:
 # http.port: 9200
 http.port: {{ .Values.service.internalPort }}

 # Set a custom allowed content length:
 # http.max_content_length: 100mb
 http.max_content_length: 100mb

 # Disable HTTP completely:
 # http.enabled: false
 http.enabled: true

 # This is specifically useful for permitting which front end Kibana Url's are permitted to access elastic search.
 http.cors.enabled: false
 http.cors.allow-origin: "/.*/"
 http.cors.allow-headers: X-Requested-With, Content-Type, Content-Length
 http.cors.allow-credentials: false
 ################################### Gateway ###################################

 # The gateway allows for persisting the cluster state between full cluster
 # restarts. Every change to the state (such as adding an index) will be stored
 # in the gateway, and when the cluster starts up for the first time,
 # it will read its state from the gateway.
 # There are several types of gateway implementations. For more information, see
 # <http://elasticsearch.org/guide/en/elasticsearch/reference/current/modules-gateway.html>.

 # The default gateway type is the "local" gateway (recommended):
 #
 #gateway.type: local
 #gateway.type: local

 # Settings below control how and when to start the initial recovery process on
 # a full cluster restart (to reuse as much local data as possible when using shared
 # gateway).

 # Allow recovery process after N nodes in a cluster are up:
 #
 # gateway.recover_after_nodes: 1
 gateway.recover_after_nodes: 1

 # Set the timeout to initiate the recovery process, once the N nodes
 # from previous setting are up (accepts time value):
 #
 #gateway.recover_after_time: 5m
 gateway.recover_after_time: 5m

 # Set how many nodes are expected in this cluster. Once these N nodes
 # are up (and recover_after_nodes is met), begin recovery process immediately
 # (without waiting for recover_after_time to expire):
 #
 # gateway.expected_nodes: 2
 gateway.expected_nodes: 2

 ############################# Recovery Throttling #############################

 # These settings allow to control the process of shards allocation between
 # nodes during initial recovery, replica allocation, rebalancing,
 # or when adding and removing nodes.

 # Set the number of concurrent recoveries happening on a node:
 #
 # 1. During the initial recovery
 #
 # cluster.routing.allocation.node_initial_primaries_recoveries: 4
 #
 # 2. During adding/removing nodes, rebalancing, etc
 #
 # cluster.routing.allocation.node_concurrent_recoveries: 2

 # Set to throttle throughput when recovering (eg. 100mb, by default 20mb):
 # indices.recovery.max_bytes_per_sec: 20mb
 indices.recovery.max_bytes_per_sec: 20mb

 # Set to limit the number of open concurrent streams when
 # recovering a shard from a peer:
 #
 # indices.recovery.concurrent_streams: 5
 indices.recovery.concurrent_streams: 5

 ################################## Discovery ##################################

 # Discovery infrastructure ensures nodes can be found within a cluster
 # and master node is elected. Multicast discovery is the default.

 # Set to ensure a node sees N other master eligible nodes to be considered
 # operational within the cluster. Its recommended to set it to a higher value
 # than 1 when running more than 2 nodes in the cluster.
 #
 discovery.zen.minimum_master_nodes: 1

 # Set the time to wait for ping responses from other nodes when discovering.
 # Set this option to a higher value on a slow or congested network
 # to minimize discovery failures:
 #
 # discovery.zen.ping.timeout: 3s
 discovery.zen.ping.timeout:

 # For more information, see
 # <http://elasticsearch.org/guide/en/elasticsearch/reference/current/modules-discovery-zen.html>

 # Unicast discovery allows to explicitly control which nodes will be used
 # to discover the cluster. It can be used when multicast is not present,
 # or to restrict the cluster communication-wise.
 #
 # 1. Disable multicast discovery (enabled by default):
 # discovery.zen.ping.multicast.enabled: false
 discovery.zen.ping.multicast.enabled: false


 # 2. Configure an initial list of master nodes in the cluster
 #    to perform discovery when new nodes (master or data) are started:
 #
 # discovery.zen.ping.unicast.hosts: ["host1", "host2:port"]
 discovery.zen.ping.unicast.hosts: ["0.0.0.0"]

 # EC2 discovery allows to use AWS EC2 API in order to perform discovery.
 #
 # You have to install the cloud-aws plugin for enabling the EC2 discovery.
 #
 # For more information, see
 # <http://elasticsearch.org/guide/en/elasticsearch/reference/current/modules-discovery-ec2.html>
 #
 #
 # See <http://elasticsearch.org/tutorials/elasticsearch-on-ec2/>
 # for a step-by-step tutorial.

 # GCE discovery allows to use Google Compute Engine API in order to perform discovery.
 #
 # You have to install the cloud-gce plugin for enabling the GCE discovery.
 #
 # For more information, see <https://github.com/elasticsearch/elasticsearch-cloud-gce>.

 # Azure discovery allows to use Azure API in order to perform discovery.
 #
 # You have to install the cloud-azure plugin for enabling the Azure discovery.
 #
 # For more information, see <https://github.com/elasticsearch/elasticsearch-cloud-azure>.
