elasticsearch

Install Elasticsearch.

Tasks

Tasks are extracted in several files, included in tasks/main.yml :

packages.yml : install packages ;
configuration.yml : configure the service;
bootstrap_checks.yml : deal with bootstrap checks;
datadir.yml : data directory customization ;
tmpdir.yml : temporary directory customization ;

Available variables

elasticsearch_cluster_name: cluster name ;
elasticsearch_node_name: node name, defaults to hostname ;
elasticsearch_network_host: which interfaces to bind to ;
elasticsearch_network_publish_host: which interface to publish ;
elasticsearch_custom_datadir: custom datadir
elasticsearch_custom_tmpdir: custom tmpdir

By default, Elasticsearch will listen to the public interfaces (_site_ cf. https://www.elastic.co/guide/en/elasticsearch/reference/5.0/important-settings.html#network.host), so you will have to secure it, with firewall rules for example.
