I have three nodes, and I want to maintain 3 primary shards and 1 replica for each index on the cluster. I know that I can specify a template by setting a template and logstash output, but is there a way to do it once and for all?

I suppose [index templates](https://www.elastic.co/guide/en/elasticsearch/reference/current/index-templates.html) is a good choice.
