puppet-elasticsearch

A puppet module for managing elasticsearch nodes

http://www.elasticsearch.org/

Usage

Installation, make sure service is running and will be started at boot time:

 class { 'elasticsearch': }

Install a certain version:

 class { 'elasticsearch':
   version => '0.90.3'
 }

This assumes an elasticsearch package is already available to your distribution's package manager. To install it in a different way:

To download from http/https/ftp source:

 class { 'elasticsearch':
   package_url => 'https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-0.90.7.deb'
 }

To download from a puppet:// source:

 class { 'elasticsearch':
   package_url => 'puppet:///path/to/elasticsearch-0.90.7.deb'
 }

Or use a local file source:

 class { 'elasticsearch':
   package_url => 'file:/path/to/elasticsearch-0.90.7.deb'
 }

Automatic upgrade of the software ( default set to false ):

 class { 'elasticsearch':
   autoupgrade => true
 }

Removal/decommissioning:

 class { 'elasticsearch':
   ensure => 'absent'
 }

Install everything but disable service(s) afterwards:

 class { 'elasticsearch':
   status => 'disabled'
 }

Disable automated restart of Elasticsearch on config file change:

 class { 'elasticsearch':
   restart_on_change => false
 }

For the config variable a hash needs to be passed:

 class { 'elasticsearch':
   config                   => {
     'node'                 => {
       'name'               => 'elasticsearch001'
     },
     'index'                => {
       'number_of_replicas' => '0',
       'number_of_shards'   => '5'
     },
     'network'              => {
       'host'               => $::ipaddress
     }
   }
 }

Short write up of the config hash is also possible.

Instead of writing the full hash representation:

 class { 'elasticsearch':
   config                 => {
     'cluster'            => {
       'name'             => 'ClusterName',
       'routing'          => {
         'allocation'     => {
           'awareness'    => {
             'attributes' => 'rack'
           }
         }
       }
     }
   }
 }

You can write the dotted key naming:

 class { 'elasticsearch':
   config => {
     'cluster' => {
       'name' => 'ClusterName',
       'routing.allocation.awareness.attributes' => 'rack'
     }
   }
 }

Manage templates

Add a new template

This will install and/or replace the template in Elasticearch

 elasticsearch::template { 'templatename':
   file => 'puppet:///path/to/template.json'
 }

Delete a template

 elasticsearch::template { 'templatename':
   ensure => 'absent'
 }

Host

Default it uses localhost:9200 as host. you can change this with the 'host' and 'port' variables

 elasticsearch::template { 'templatename':
   host => $::ipaddress,
   port => 9200
 }

Bindings / clients

Install a variety of clients/bindings:

Python

 elasticsearch::python { 'rawes': }

Ruby

 elasticsearch::ruby { 'elasticsearch': }

Plugins

Install a variety of plugins:

From official repository:

 elasticsearch::plugin{'mobz/elasticsearch-head':
   module_dir => 'head'
 }

From custom url:

 elasticsearch::plugin{ 'elasticsearch-jetty':
   module_dir => 'jetty',
   url        => 'https://oss-es-plugins.s3.amazonaws.com/elasticsearch-jetty/elasticsearch-jetty-0.90.0.zip'
 }

Java install

For those that have no separate module for installation of java:

 class { 'elasticsearch':
   java_install => true
 }

If you want a specific java package/version:

 class { 'elasticsearch':
   java_install => true,
   java_package => 'packagename'
 }

Service providers

Currently only the 'init' service provider is supported but others can be implemented quite easy.

init

Defaults file

You can populate the defaults file ( /etc/defaults/elasticsearch or /etc/sysconfig/elasticsearch )

hash representation

 class { 'elasticsearch':
   init_defaults => { 'ES_USER' => 'elasticsearch', 'ES_GROUP' => 'elasticsearch' }
 }

file source

 class { 'elasticsearch':
   init_defaults_file => 'puppet:///path/to/defaults'
 }
