Running multiple isolated DeepStack instances

I can run multiple DeepStack instances on the same host, they use the same data. For example, if I register faces on one instances, they are ‘visible’ in all the others.
How can I make the data of these instances isolated from each other?

Maybe an overkill solution, but you could run them in Docker containers.

You probably want to mount in different volumes to the two instances, or else they will be accessing the same sqlite files
