This is an Ansible playbook for Elasticsearch.

• Support for installing plugins
• Support for installing custom JARs in the Elasticsearch classpath (e.g. custom Lucene Similarity JAR)
• Support for installing the Marvel plugin

• Java (version 8 recommended)
• Maven (3.1 or higher)

• elasticsearch_version - Elasticsearch version to install (default: 1.5.2)
• elasticsearch_network_http_port - Elasticsearch http port (default: 9200)
• elasticsearch_service_startonboot - Make sure Elasticsearch service is running after system boot (default: yes)
• elasticsearch_service_state - Run Elasticsearch service (default: started)

You will need to define an array called elasticsearch_plugins in the host/group vars file, such that:

elasticsearch_plugins:
 - { name: '<plugin name>', url: '<[optional] plugin url>' }
 - ...

By default searchguard, head and analysis-icu plugins are installed (see defaults/main.yml).

Concerning searchguard plugin it is important to note that it didn't support Elasticsearcl 1.7 yet. Otherwise, for the >1.7 versions it is possible to build and/or install the plugin. Just set the elasticsearch_install_searchguard flag to tue (enabled by default). The search-guard plugin should not be specified within "elasticsearch_plugins" list as it will has a custom installation.

Custom jars are made available to the Elasticsearch classpath by being downloaded into the elasticsearch_home_dir/lib folder. You will need to define an array called elasticsearch_custom_jars in the corresponding playbook or inventory file, such that:

elasticsearch_custom_jars:
 - { uri: '<URL where JAR can be downloaded from: required>', filename: '<alternative name for final JAR if different from file downladed: leave blank to use same filename>', user: '<BASIC auth username: leave blank of not needed>', passwd: '<BASIC auth password: leave blank of not needed>' }
 - ...

Elasticsearch thread pools can be configured using the elasticsearch_thread_pools list variable:

elasticsearch_thread_pools:
  - "threadpool.bulk.type: fixed"
  - "threadpool.bulk.size: 50"
  - "threadpool.bulk.queue_size: 1000"

The following variables need to be defined in the playbook or inventory:

• elasticsearch_plugin_marvel_version

The following variables provide configuration for the plugin. More options may be available in the future (see http://www.elasticsearch.org/guide/en/marvel/current/#stats-export):

• elasticsearch_plugin_marvel_agent_enabled
• elasticsearch_plugin_marvel_agent_exporter_es_hosts
• elasticsearch_plugin_marvel_agent_indices
• elasticsearch_plugin_marvel_agent_interval
• elasticsearch_plugin_marvel_agent_exporter_es_index_timeformat

If you prefer to set the time zone, typically if you are not using ntp, use the elasticsearch_timezone parameter:

elasticsearch_timezone: "Europe/Paris"
