[FEATURE] CRD to add data-streams and indices

[moglitsch]

Is your feature request related to a problem?

It would be nice to have the possibility to create data-streams/indices by CRD.

What solution would you like?

The CRD can manage which data-streams/indices will be deployed.

What alternatives have you considered?

Run an ansible-job.

Do you have any additional context?

None

You can already do that by using the templates :) https://github.com/opensearch-project/opensearch-k8s-operator/blob/main/charts/opensearch-operator/files/opensearch.opster.io_opensearchindextemplates.yaml

Thanks for the quick response.

I was already aware of the option using the index template.

The problem with the index template is that the index/data stream is only created when an event is received from OpenSearch for the first time.

However, the wish would be to create the indices/data stream in advance.

Might be worth trying creating your indexes with the "curator" like this :
