oh you ment with testnet tool? I will have to compile how to, and its kinda difficult you need to setup digitalocean also ssh ids in a file also request 11 nodes in the settings of digitalocean (new users got 10 nodes limit)
edit: theoretically I could make a script that you could run a network on any VPS with just one node! actually I got it ready! see GitHub - dreamerchris/sn_node_joiner: sets up multiple nodes in a debian/manjaro machine either join dreamnet/playground or launch your own net
