I can’t answer that, but, I have no need for Dockge. It’s just another thing to deal with. I greatly prefer the minimum software I need. Using this technique, I still get update notices, click update, and it rebuilds and downloads as needed. Can’t be simpler. I don’t want to do auto updates so that is not an issue either. I suspect it’s personal preference and some guides out there that people read. There’s nothing wrong with using it or portainer, etc. Whatever you prefer.
