I am trying to deploy production grade Elastic Search 6.3.0 on Kubernetes.

Came across few articles, but still not sure what is the best approach to go with.

1. https://github.com/pires/kubernetes-elasticsearch-cluster

It doesnt use stateful set.

2. https://anchormen.nl/blog/big-data-services/elastic-search-deployment-kubernetes/

This is pretty old.

Using elastic search for App search.

Images from ElasticSearch are

docker pull docker.elastic.co/elasticsearch/elasticsearch:6.3.0
docker pull docker.elastic.co/elasticsearch/elasticsearch-oss:6.3.0

I would like to go with -oss image and it is the core apache one.

Is there any good documentation on setting up production grade 6.3.0 version on Kubernetes.

Thanks
