Configuring index template to set number of shards

Elastic Stack Elasticsearch
1

Hi

I was wondering how one would be able to change the default index template. For instance, I would like to configure the number of primary and replica shards for each index.

Is there a way to do it without the API? This is because Logstash is listening in on a live Kafka outlet, so data is almost immediately ingested when my ELK stack boots up.

Any help or direction appreciated.

Thanks!

you can define the index template on the es output in logstash
https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-template
and following options

so that logstash will automatically install the index template on startup
