Using Elasticsearch Curator to Reindex Data

Today I was using Elasticsearch Curator to reindex indices that was created on a daily basis, to reindex all the data to one index. I used this route as the old data will not be accessed frequently.

Install Elasticsearch Curator

1
2
$ docker run -it python:2.7-alpine sh
$ pip install elasticsearch-curator

Create Configs:

Create the curator config:

config.yml

# Remember, leave a key empty if there is no value.  None will be a string,
# not a Python "NoneType"
client:
  hosts:
    - es.endpoint.com
  port: 443
  use_ssl: True
  ssl_no_validate: False
  http_auth: admin:pass
  timeout: 30
  master_only: False

logging:
  loglevel: INFO
  logfile:
  logformat: default
  blacklist: ['urllib3']

Create the action config:

# 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:
    description: "Reindex index-2017.10.{30,31} into new-index-2017.10"
    action: reindex
    options:
      disable_action: False
      wait_interval: 9
      max_wait: -1
      request_body:
        source:
          index: ['index-2017.10.*']
        dest:
          index: new-index-2017.10
    filters:
    - filtertype: none

Create the Elasticsearch Index:

Create the Index where we will reindex the data to:

1
$ curl -XPUT http://es.endpoint.com/new-index-2017.10 -d '{"settings": {"number_of_shards": 5, "number_of_replicas": 1}}'

Run the Curator:

$ curator --config curator.yml action-reindex.yml
