Not sure all the hate with Docker. It works and has a good ecosystem.

The DB command in the first approach seems like something docker got rid of a long time back when they deprecated the —link stuff. Just create a network and attach containers to it and then you get DNS for free.

Flockport uses a standard networking bridge served by a Dnsmasq instance that all containers connect to. They all get their IP by DHCP unless you set static IPs and can be discovered by their name on local systems.

The DB command basically rolls out a fresh Mysql or Postgresql container instance and sets up the databases. The discovery happens over dns.
