I have a quick question, I'm using localstack in our local testing environment and I want to have Elasticsearch persist it's data across sessions.

I've noticed that running docker-compose down and docker-compose up in our environment causes the ES service deletes it's data every time on startup

https://github.com/localstack/localstack/blob/master/localstack/services/es/es_starter.py#L39

Services like S3 do seem to persist, is there a way around this for ES or was this done by design? In the latter case would you guys accept PR's to allow for persistance of ES data?

Kind regards,
