elasticsearch-changer-index-template

This script can automate change indexes templates for all index in cluster and put pre settings for new indecies

Case: You have 2 data nodes and 2 primary shard in index template. You add third data nodes and you need to increase primary shard in all index templates.

Usually we set index name, ilm policy, index template, index aliases names the same as index name

Scripts get all index template in ElasticSearch (except system indices started from .*), set new settings, compare between old template and new and put changed template to ElasticSearch
