Defined Type: elasticsearch::plugin

Defined in:
manifests/plugin.pp

Overview

This define allows you to install arbitrary Elasticsearch plugins either by using the default repositories or by specifying an URL

All default values are defined in the elasticsearch::params class.

Examples:

install from official repository

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

installation using a custom URL

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

Parameters:

  • ensure (String) (defaults to: 'present') —

    Whether the plugin will be installed or removed. Set to ‘absent’ to ensure a plugin is not installed

  • instances (Enum[String, Array]) (defaults to: undef) —

    Specify all the instances related

  • module_dir (String) (defaults to: undef) —

    Directory name where the module has been installed This is automatically generated based on the module name Specify a value here to override the auto generated value

  • proxy_host (String) (defaults to: undef) —

    Proxy host to use when installing the plugin

  • proxy_password (String) (defaults to: undef) —

    Proxy auth password to use when installing the plugin

  • proxy_port (Integer) (defaults to: undef) —

    Proxy port to use when installing the plugin

  • proxy_username (String) (defaults to: undef) —

    Proxy auth username to use when installing the plugin

  • source (String) (defaults to: undef) —
