[Bug]: unable to create ingress object in openshift

[alexlionnel]

Describe the bug
Ingress resource is not created when i create a grafana instance using grafana operator

Version
I am using grafana-operator v5.8.0 and openshift 4.12.53

To Reproduce
Steps to reproduce the behavior:

1. Install grafana-operator from openshift interface
2. create a grafana ressource using this yml config

apiVersion: grafana.integreatly.org/v1beta1
kind: Grafana
metadata:
  name: grafana
  labels:
    dashboards: "grafana"
  namespace: grafana-project
spec:
  config:
    log:
      mode: "console"
    auth:
      disable_login_form: "false"
    security:
      admin_user: root
      admin_password: secret
  ingress:
    spec:
      ingressClassName: openshift-default
      rules:
        - host: <my_domain.com>
          http:
            paths:
              - backend:
                  service:
                    name: grafana-service
                    port:
                      number: 3000
                path: /
                pathType: Prefix

Expected behavior
Ingress resource should be created but it isn't
Same result with ingressClassName: nginx

@alexlionnel do you want to use ingress, or do you actually want to use OCP routes?
There is a root object that you can use instead grafana.spec.route

If I remember correctly, we have more or less removed the possibility to create an ingress from OCP users without thinking of it.

In fact, i want to use an ingress with tls config, using cert manager

 ingress:
    metadata:
      cert-manager.io/cluster-issuer: letsencrypt-issuer
    spec:
      ingressClassName: openshift-default
      tls:
        - hosts:
          - <my_domain.com>
        secretName: secret-cert-tls
      rules:
        - host: <my_domain.com>
          http:
            paths:
              - backend:
                  service:
                    name: grafana-service
                    port:
                      number: 3000
                path: /
                pathType: Prefix

But ingress is not created

[NissesSenap]

With our current implementation, that is not possible.
We did an assumption that anyone using OCP would only want to use routes.

grafana-operator/controllers/reconcilers/grafana/ingress_reconciler.go

Lines 35 to 45 in e43aff9

	func (r *IngressReconciler) Reconcile(ctx context.Context, cr *v1beta1.Grafana, status *v1beta1.GrafanaStatus, vars *v1beta1.OperatorReconcileVars, scheme *runtime.Scheme) (v1beta1.OperatorStageStatus, error) {
	logger := log.FromContext(ctx).WithName("IngressReconciler")
	if r.isOpenShift {
	logger.Info("reconciling route", "platform", "openshift")
	return r.reconcileRoute(ctx, cr, status, vars, scheme)
	} else {
	logger.Info("reconciling ingress", "platform", "kubernetes")
	return r.reconcileIngress(ctx, cr, status, vars, scheme)
	}
	}

As a workaround, I recommend that you setup an ingress separately from the operator.
I will mark this as a bug, if you or someone else have time to create a fix for this, that would be great.
The maintainers have lots to do, and I don't think this will be a priority one thing for us to solve.

Sorry for the inconvenience.
