Yeah, I think in this case a way to manage different cloudrons in a centralized way would be the way to go.
For me, the main objective would be to install an app from my admin interface and have it go up in a specific machine, with domains and certificates working accordingly and such.
Haven't been able to go on with the raspberry pi setup, as my provider only has NAS disks, and overlay doesn't support it, and the other storage drivers were such a pain to setup I couldn't get it to work.
Looking for a provider with a better setup (and closer to what one would have at home) to try.
Edit: I'm sorry for the raspberry pi talk, I got the threads mixed up. But yeah, my "dream" multi-node setup is basically being able to install apps on different machines from the same web/cli interface.
