Il est possible d'explicite la conf dans Docker-compose

networks:
  backend:

networks:
  backend:
    ipam:
      driver: default
      config:
        - subnet: 192.168.10.0/24

Il est possible de faire :

networks:
  hostnw:
    external:
      name: host

Mais il est mieux de faire

services:
  webapp:
    build: .
    network_mode: "host"
