i have to check for mandatory values based on some condition.
my values.yaml is as below

id:3
test:
 id: 2
 test1:
  id: 1

In my template, i need to check if id is present at .Values.test.test1.id and assign that value. If not fall back to .Values.test.id and at last .Values.id. But id has to be mandatory and i need to use required function.

my template is as below

{{- if .Values.test.test1.id }}
<assign> {{ .Values.test.test1.id }}
{{- else }}
{{- $id := .Values.test.id }}
{{- $id2 := .Values.id }}
<assign> <need to check required with or of $id $id2> </assign>
{{- end }}

What is the best way to achieve this?
