I am ignorant of Dockers and virtualization, so this question might be silly. I have a single RPi. I got to run a Pi-hole project based on BalenaOS on it. Now, I want to run another BalenaCloud application or project alongside on the same device. However, all the tutorials for projects spins up a new image to be flashed per application. Does it mean I can only run one application on a device? If not, how can I run two or more stuff on the same device?
Update: I did read the Multiple Containers doc page. Unfortunately I do not understand it at all.
