the scripts will most probably be used in development environment where there might be also other local containers running, i don't think it's fine to stop and prune all containers, we should stop only the intended containers

interesting, so you actually use a lot of the existing testnet scripts configuration functions 🤔

yep, it's mostly the same configuration. The only difference in configuration are the ports and the ip addresses.

right, I've noticed that: the first question was: how was possible to function if all nodes run on the same ports. But then I've saw the IPs.
