That is very interesting (not to say wise): dokku uses the docker ip address instead of binding to localhost.

This way the machine will never have conflict with port :) (and because of that it is possible to "scale", it will be in the same host, but yet :P )

It is not possible of doing this manually (or using capistrano) because we will need to update nginx each time 🤔.
