Values.Yaml

env:
  isTest: 'true'
  hostData:
  - isActive: true
    name: a
    url: testA
  - isActive: true
    name: A
    url: testB

configmap.yaml

test:    
  {{- with .Values.env }}
  hostData: {{ .hostData | toJson}}
  isTest: {{ .isTest}}  
  {{- end }}

Now I want to update the url of hostData I tried to add

test:    
  {{- with .Values.env }}
  hostData: {{ .hostData | toJson}}
  isTest: {{ .isTest}}  
  {{- end }}
  {{- range .Values.env.hostData}}
  url: https://{{ .name}}//newName
  {{- end }}

But it add the url to the structure of the test

test:
  hostData: [{"isActive":true,"name":A","url":"testA"},{"isActive":true,"name":"B","url":"testB"}
  url AnewName
  url BnewName

and didn't update the hostData-> url This is the resuLT I want

test:
   hostData: [{"isActive":true,"name":AnewName","url":"testA"},{"isActive":true,"name":"BnewName","url":"testB"}]

I tried to create also tpl file and added my logic but the problem that I didn't succeed to return yaml from the tpl

{{/*
Create hostData
*/}}
{{- define "get-hostData" -}}
{{- range .Values.env.hostData}}
hostData:
  - isActive: {{ .isActive }}
    name: {{ .name }}
    url: {{ newUrlFromValues }}
{{- end }}

The problem that in the config it didn`t return yaml but string

{{- $test1 := include "get-hostData" . }}

maybe I need to return it as json array
