I have a setup kubernetes cluster with Elasticsearch and I need enable CORS on ES.

ES endpoint works fine it's searchable. But i'am using a plugin to call ES, and only request its made is with OPTIONS e that's it.

But i can't find the elasticsearch.yml.

I can see a bunch of .yml config, from cluster, pods, application, storage and services.

How can I change ES config with this setup?

I've already try going to Applications and change the .yaml, but seems my changes take no effect after I click on "save" button.
