Overriding elasticsearch.yml

[Yitaek]

If I want to override elasticsearch.yml (for example, increasing the thread pool queue size), is there an easy way to do so using values.yaml?

pires/kubernetes-elasticsearch-cluster README seems to suggest that I need to mount my own file and add the ES_PATH_CONF env variable. Could you provide some more detail on how I can accomplish that using this helm chart?

Thanks in advance!

See #39 and pires/kubernetes-elasticsearch-cluster#71
Either way you need an elasticsearch.yml with the setting you want, perhaps using variable substitution like above. ${ENV_VARIABLE_NAME}
I like the configmap approach in links above, but haven't tested the pull requests.
