In my attempt to optimize the GreenBlue Controller's code based on the suggestions from issue #46, I realized that the modifications I implemented were excessively substantial. Consequently, I am exploring ways to streamline the code, and I am in search of appropriate design patterns that could facilitate this simplification. Should you have any valuable suggestions, please do not hesitate to share.

Hi @Chever-John

Thanks for your PR. I believe you were trying to tackle #46, correct?

I that's the case we'd rather see a small PR changing concrete pieces of code rather than introduce a whole new file.

You might want to try looking into changing the signature of the Reconcile() func and then using it like so

builder.ControllerManagedBy(manager).
	For(&corev1.ConfigMap{}).
	Complete(reconcile.AsReconciler(client, &MyObjectReconciler{}))

If you still need a hand don't hesitate to ask.
