Does anyone have experience running Elasticsearch as a kubernetes deployment? Can you just spin up some big-RAM containers attached to persisted volumes?

Elastic Co. seems to have an offering specialized for k8s: https://www.elastic.co/elastic-cloud-kubernetes but I can't understand what it does exactly.

Our data is not crazy-big and it doesn't need to be super performant, but for operational simplicity I'd like to deploy as part of the production cluster like all our other app containers rather than some "special" type of container.
