Setting heap size and jvm parameters on elastic docker image

Elastic Stack Elasticsearch
1

Hi

I am using elasticsearch.k8s.elastic.co/v1 to deploy Elasticsearch defined here

When I have deployed to Kubernetes, I notice that the heap size is set to 1GB. I would like to increase it to 4GB.

How can I set the java override options and "-Xms1g -Xmx1g " via this yaml?

Thanks

Joe

How do I do it using this configuration? I notice that that spec uses a container.

apiVersion: elasticsearch.k8s.elastic.co/v1
kind: Elasticsearch

      podTemplate:
