Hi

I am using [elasticsearch.k8s.elastic.co/v1](http://elasticsearch.k8s.elastic.co/v1) to deploy Elasticsearch defined here

> **[Deploy an Elasticsearch cluster | Elastic Cloud on Kubernetes \[1.2\] | Elastic](https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-deploy-elasticsearch.html)**

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.

```auto
