Hi,

Assuming I have a lot of index templates and I want to update the same setting on all of them (change the number of primary or replica shards for example) is there a way to update all of the templates using a simple call to api?

the only way I know for the template update is to get the current template, change what I want and then PUT the updated template with the same name so it will override.

is there a better way?

many thanks!

Hi,

it depends how you have specified your templates but it is possible that [multiple index templates match an index](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-templates.html#multiple-templates). This means you could define a "base template" that matches all indices that you are interested in and then more specific templates that only match certain indices.
