Two OH instances on Docker on Synology NAS possible?

I have OH3 on my Synology NAS on a test basis via Docker.
Basically, I followed these instructions:

… i.e. I have created / mounted extra paths:

My question (… and once again its clear that i’m a simple user) is the following: if I want to install a second instance (e.g. after Milestone4 and Milestone5 in parallel) - can this work? The two Openhab instances surely can’t share common paths, can they?

Thanks in advance

Yes, this can and will work…
… If you change the ports to avoid conflicts
… If you create individual shared folders for each container
… If you think about interaction between the 2 instances when running in parallel and writing to the same physical devices… This can get a little bit messy depending on the technology
