Rollover

action: rollover
description: >-
  Rollover the index associated with alias 'aliasname', which should be in the
  form of prefix-000001 (or similar), or prefix-YYYY.MM.DD-1.
options:
  name: aliasname
  conditions:
    max_age: 1d
    max_docs: 1000000
    max_size: 5gb

This action uses the Elasticsearch Rollover API to create a new index, if any of the described conditions are met.

The extra_settings option allows the addition of extra index settings (but not mappings). An example of how these settings can be used might be:
