Нужно убрать network_mode: host. И тогда не придётся разносить инстансы на разные порты.
Хардкодить ИПы тоже плохая практика, нет грантий что они всегда будут такими.
И параметры лучше передавать через переменные окружения.

Нет смысла разносить по портам, у тебя есть разные хосты с уникальными ИПами. И посмотри на каком адресе ты слушаешь подключения.
