##https://stackoverflow.com/questions/67380335/how-to-fetch-a-value-inside-an-array-using-helm-template
so the values.yaml looks something like
########values.yaml########
ep:
staging:
ricochet:
ash: val1
mini: val2
pikachu:
ash: val3
production:
ricochet:
ash: val4
mini: val5
pikachu:
ash: val6
#####another-values.yaml#########
doraemon:
gadget1: ricochet
gadget2: ash
env: staging
##Endgoal: how to get val1 dynamically?
##this works,
####{{ (index .Values "ep" "staging" "ricochet" "ash")
##but how to derive staging from values.yaml itself?
##this fails,
{{ (index .Values "ep" .Values.doraemon.env .Values.doraemon.gadget1 .Values.doraemon.gadget2) }}

{{ (index .Values "ep" (index .Values.doraemon "env") (index .Values.doraemon "gadget1") (index .Values.doraemon "gadget2")) }}

This is how it works

For readability can use the following as well

{{- with $doraemon := .Values.doraemon -}}
{{- (index .Values "ep" $doraemon.env $doraemon.gadget1 $doraemon.gadget2) -}}
