Menghapus Elasticsearch Indices dengan Curator Bag (2)

Dulu pernah menggunakan curator_cli untuk menghapus indices. Namun config yang lama tidak bisa digunakan untuk ES 5.2.x. Mari kita coba cara baru ini (ndak baru-baru amat sih).

1. Install curator (via pip)

   $ pip install elasticsearch-curator
   

2. Perintah dasar curator adalah:

   $ curator [--config CONFIG.YML] [--dry-run] ACTION_FILE.YML
   

3. Atur configurasi dalam file config.yml

   $ cd ~
   $ vim config.yml
   

   Isinya kira-kira begini:

   ---
   # Remember, leave a key empty if there is no value.  None will be a string,
   # not a Python "NoneType"
   client:
     hosts:
       - 192.168.33.201 #ip publish es
     port: 9200
     url_prefix:
     use_ssl: False
     certificate:
     client_cert:
     client_key:
     ssl_no_validate: False
     http_auth:
     timeout: 30
     master_only: False
   
   logging:
     loglevel: INFO
     logfile:
     logformat: default
     blacklist: ['elasticsearch', 'urllib3']
   

4. Atur aksi yang akan dilakukan dalam file delete_indices.yml

   $ vim delete_indices.yml
   

   Isinya kira-kira begini:

   ---
   # Remember, leave a key empty if there is no value.  None will be a string,
   # not a Python "NoneType"
   #
   # Also remember that all examples have 'disable_action' set to True.  If you
   # want to use this action as a template, be sure to set this to False after
   # copying it.
   actions:
     1:
       action: delete_indices
       description: >-
         Delete indices older than 7 days (based on index name), #for filebeat-
         prefixed indices. Ignore the error if the filter does not result in an
         actionable list of indices (ignore_empty_list) and exit cleanly.
       options:
         ignore_empty_list: True
         disable_action: False
       filters:
       #- filtertype: pattern
       #  kind: prefix
       #  value: filebeat-
       - filtertype: age
         source: name
         direction: older
         timestring: '%Y.%m.%d'
         unit: days
         unit_count: 7
   

5. Testing konfigurasi curator.

   $ curator --config config.yml delete_indices.yml
   

6. Atur penjadwalan curator dalam crontab

   $ crontab -e
   

   Isi cron kira-kira begini:

   0 6 * * * /usr/local/bin/curator --config /home/user/config.yml /home/user/delete_indices.yml
   

Selesai.
