Google Container Registry images lifecycle

Question

I would like to know if there is a way to setup an objects lifecycle in GCP Container Registry?

I would like to keep the last n versions of an image, automatically deleting the older ones as new ones are pushed online.

I can't work directly on the Cloud Storage bucket because, having multiple images saved, the storage objects are not recognizable.

Seth Vargo, a Google Cloud developer advocate has release GCRCleaner.

Follow the instruction for setting up a scheduler and a Cloud Run for cleaning the GCR.

The GCRCleaner functionality is now baked in to the GCR Registry itself. It's disclamed in the GCRCleaner homepage, and refers here:
