Overview

In all versions between 8.3 to alpha-8.8, we assume that auth via username and password is for external Elasticsearch only, which is not always correct.

Here is an example from Optimize config:

{{- if .Values.global.elasticsearch.external }}
authentication:
  username: {{ .Values.global.elasticsearch.auth.username | quote }}
{{- end }}

Actions

• Support auth for any ES instance even for the embedded with the chart.

Sub-tasks

• sub-task

Given all of the bitnami issues we've had in the past year and our future plans to only support external elasticsearch, I think it's best to close this as wontfix.
