How can I check how many shards I have for an index?

Elastic Stack Elasticsearch
1

I'm using this command

curl -X GET http://elasticsearch:9200/my-index-*/_settings?pretty

and I'm getting "number_of_shards": "1".

Which doesn't make much sense, because when the index is created on runtime, no settings related to shards are defined. And as far as I know the default number of shards is 5(correct if I'm wrong).

In recent versions the default number of primary shards is 1.

Could you please clarify in which version this changed(or provide me a link)?

Have a look at this:
