imageName and registry vars problem : not always same behavior

To customize Helm Chart values file in addons, we could use these vars, for example for Nextcloud deployment :

  chart:
    repoUrl: https://nextcloud.github.io/helm
    version: 6.2.1
    registry: docker.io
    imageName: nextcloud
    imageTag: 28.0.11

In some addons default templates vars, we've got imageName defined like this :

imageName: hub.eole.education/eole3/screego-container-image/screego or

imageName: hub.eole.education/eole3/nextcloud-container-image/nextcloud

It should be defined like this :

registry: hub.eole.education/eole3/nextcloud-container-image
imageName: nextcloud

Is it possible to update this implementaion and adapt it on all Eole³ Tools addons please ?

To be functional, we need parse registry value. Example in addons/collabora/templates/collabora-values.yaml :

{%- set registry = get_value(config, "collabora", 'chart:registry') -%}
{%- set imageName = get_value(config, "collabora", 'chart:imageName') -%}
{%- set imageTag = get_value(config, "collabora", 'chart:imageTag') -%}
image:
  repository: {{ registry }}/{{ imageName }}
  tag: {{ imageTag }}

Not present in addons/nextcloud/templates/nextcloud-values.yaml :

nameOverride: "{{ config['nextcloud']['hostname'] }}"
fullnameOverride: "{{ config['nextcloud']['hostname'] }}"
image:
  repository: {{ config['nextcloud']['chart']['imageName'] }}

Incomplete or partially good in Screego ? (no image section)

{%- if get_value(config, "screego", "chart:registry") != "upstream" %}
{{ main_image(config, "screego", "screego", image_key="repository") }}
{%- endif %}

The best behavior should be :

image:
  repository: {{ config['nextcloud']['chart']['registry'] }}/{{ config['nextcloud']['chart']['imageName'] }}
  tag: {{ config['nextcloud']['chart']['imageTag'] }}
