Changes applied to `NgrokModuleSet` do not propagate to managed `Edge`

[pmalek]

What happened

After applying NgrokModuleSet with e.g. oauth set to google email address and changing the email address there's no change in the managed Edge.

What you think should happen instead

After applying NgrokModuleSet with e.g. oauth set to google email address and changing the email address, managed Edge should be changed

How to reproduce

1. Apply (e.g. via kubectl apply ...) below listed manifest (substitute domain and email address with your own)

   apiVersion: v1
   kind: Service
   metadata:
     name: proxy
     namespace: infra
   spec:
     ports:
     - name: http
       port: 80
       targetPort: 80
     selector:
       app: httpbin
   ---
   apiVersion: apps/v1
   kind: Deployment
   metadata:
     name: httpbin
     namespace: infra
   spec:
     replicas: 1
     selector:
       matchLabels:
         app: httpbin
     template:
       metadata:
         labels:
           app: httpbin
       spec:
         containers:
         - image: kong/httpbin:0.1.0
           name: httpbin
           ports:
           - containerPort: 80
   ---
   apiVersion: networking.k8s.io/v1
   kind: Ingress
   metadata:
     name: proxy
     namespace: infra
     annotations:
       k8s.ngrok.com/modules: oauth
   spec:
     ingressClassName: ngrok
     rules:
     - host: <DOMAIN>.ngrok-free.app
       http:
         paths:
         - path: /
           pathType: Prefix
           backend:
             service:
               name: proxy
               port:
                 number: 80
   ---
   kind: NgrokModuleSet
   apiVersion: ingress.k8s.ngrok.com/v1alpha1
   metadata:
     name: oauth
     namespace: infra
   modules:
     oauth:
       google:
         emailAddresses:
         - <EMAIL>

2. Verify that you can access <DOMAIN> using <EMAIL> address via google authentication.

3. Change <EMAIL> to <EMAIL2> and apply the changes (e.g. kubectl apply ...)

4. Verify that you can still access <DOMAIN> using <EMAIL> address via google authentication and not via <EMAIL2>

Thank you for the report @pmalek ! Currently, the controller is watching NgrokModuleSet CRs for changes, but it is not triggering reconciliation. We’ll be looking into addressing this gotcha next, but for the time being, operators either need to restart the controller or change some of the ingress objects to trigger reconciliation. One neat way you could do this is to create and set a new NgrokModuleSet CR for your ingress, instead of updating the old CR.

Also, we are happy to look over a PR if you wanna explore the fix yourself.

Thanks for response. I'll wait until you provide the fix as it's not obvious to me where and how to change (ingress controller https://github.com/ngrok/kubernetes-ingress-controller/blob/main/internal/controllers/ingress_controller.go I suppose) the code to make it work.
