Route resource issues

[wiiaam]

There are a couple of issues with the current Route template, specifically the implementation of https redirects.

helm-charts/charts/open-webui/templates/route.yaml

Lines 54 to 64 in 71222d2

	parentRefs:
	{{- range .Values.route.parentRefs }}
	- {{ toYaml (omit . "sectionName") | nindent 4 | trim }}
	{{- if $.Values.route.httpsRedirect }}
	sectionName: https
	{{- else if not .sectionName }}
	sectionName: http
	{{- else }}
	sectionName: {{ .sectionName }}
	{{- end }}
	{{- end }}

1. If sectionName is not specified in parentRefs, the template will force sectionName: http to be applied. parentRefs should instead be left untouched unless httpsRedirect is enabled, as it's common to not specify a sectionName and allow the route to bind to all listeners.

2. With httpsRedirect: true, the sectionName in the main https route is not configurable, and is hardcoded to https. Configuration of sectionName in what you would assume to be the main route configuration is actually reflected in the new redirect route.

I can see the benefit in having an httpsRedirect option, but right now the current implementation is restrictive. A configuration option should be available to change either sectionName or parentRefs in the redirect route. parentRefs in the main route should be left as is, unless sectionName is omitted, where a default of https can be used.

The better approach for this, which a lot of charts are doing, is to allow individual configuration of separate routes in the route: section, similar to this:

route:
  main:
    # main route, including parentRefs pointing to https listener
  redirect:
    # redirect route, including parentRefs pointing to http listener
    httpsRedirect: true

Unfortunately this will likely be a breaking change but I would consider making it now before GatewayAPI starts to overtake Ingress.
