Elasticsearch Index Lifecycle Management based on index name

Question

Is it possible to set up ES Index Lifecycle Management to delete an index based on the name that has a date in it, i.e. my_index_yyyy_MM_dd, instead of index age?

Answer 1

Unfortunately, no - ILM only supports age-based phase transitions, which is (to my knowledge) determined by the index creation_date.

To support pattern matching deletes, I'd recommend using the delete_indices action of Curator (https://www.elastic.co/guide/en/elasticsearch/client/curator/current/delete_indices.html) with the appropriate filters for your use-case.
