Overview

A puppet module for installing and configuring elastic-curator. This module was forked from jlambert121-curator and updated for curator4

Module Description

Curator is used to manage and clean up time-series elasticsearch indexes, this module manages curator.

NOTE: If you are using curator < 4.0.0 use a previous version of this module.

The original module allowed you to create various cron jobs for curator.

The new module will only create the config file, one action file and ensure the last folder of the path. If there is more than one (folder-)level missing you will have to create that folders externally before this module runs. e.g. "/etc/curator/my_settings/" you have to ensure that "/etc/curator" is present.

Also, now it is your job to create the cron job:

  cron { "curator_run":
    ensure  => 'present',
    command => '/bin/curator /root/.curator/actions.yml >/dev/null',
    hour    => 1,
    minute  => 10,
    weekday => '*',
  }

Setup

What curator affects

• curator package
• curator config

Beginning with curator

    continue_if_exception => 'True',
    filters               => [
      {
        'filtertype' => 'age',
        'direction'  => 'older',
        'timestring' => '"%Y.%m.%d"',
        'unit'       => 'days',
        'unit_count' => '2',
        'source'     => 'name',
      }
    ]
  }

Delete logstash indexes older than a week

  curator::action { 'delete_indices':
    action                => 'delete_indices',
    continue_if_exception => 'True',
    filters               => [
      {
        'filtertype' => 'pattern',
        'value'      => 'logstash-',
        'kind'       => 'prefix',
      },
      {
        'filtertype' => 'age',
        'direction'  => 'older',
        'timestring' => '"%Y.%m.%d"',
        'unit'       => 'days',
        'unit_count' => '7',
        'source'     => 'name',
      }
    ]
  }

Currently this package supports installing curator via pip or your local package manager. RPM packages can easly be created by running:

fpm -s python -t rpm urllib3
fpm -s python -t rpm elasticsearch
fpm -s python -t rpm click
fpm -s python -t rpm elasticsearch-curator
