android - How to make docker-compose django server run on local wifi network, so our iOS developer can test the API from the iPhone device?

Question

I'm trying to serve django on our local wifi IP, so our client developer can use his iOS device to test the API. The problem is that when I run the containers, it's only accessible from my chrome browser as localhost(=chrome browser run on the same macbook that is used to run the containers)

My docker-compose file:

version: '3'

volumes:
  dev_postgres_data: {}
  dev_postgres_data_backups: {}

services:
  django:
    build:
      context: .
      dockerfile: ./compose/dev/django/Dockerfile
    image: apps_dev_django
    container_name: django
    depends_on:
      - postgres
    volumes:
      - .:/app:z
    env_file:
      - ./.envs/.dev/.django
      - ./.envs/.dev/.postgres
    ports:
      - "8000:8000"
    command: /start

  postgres:
    build:
      context: .
      dockerfile: ./compose/production/postgres/Dockerfile
    image: apps_production_postgres
    container_name: postgres
    volumes:
      - dev_postgres_data:/var/lib/postgresql/data:Z
      - dev_postgres_data_backups:/backups:z
    env_file:
      - ./.envs/.dev/.postgres
    # ports must be set to use postgres container alone
    ports:
      - "5432:5432"

If I run the django server locally(=not using docker-compose)with the command python manage.py runserver 192.168.0.255:8000, the client who is using the same wifi as me can access the API. I got the 192.168.0.255 with the command ifconfig | grep "inet " | grep -v 127.0.0.1 | cut -d -f6(something I got after some googling).

If I run ifconfig, I get,

...
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        options=400<CHANNEL_IO>
        ether a4:5e:60:f1:cb:5b
        inet6 fe80::85:51dd:e37a:5435%en0 prefixlen 64 secured scopeid 0x4
        inet 192.168.0.17 netmask 0xffffff00 broadcast 192.168.0.255
        nd6 options=201<PERFORMNUD,DAD>
        media: autoselect
        status: active
...

Is there a way to run the docker-compose on my local wifi, so I can let the client developers who's on the same wifi to access the API? Thanks.

(Edited) The following does not seem to work neither :(

Thanks for the help. But this configuration does not seem to work.

```docker
...
services:
  django:
    ...
    networks:
      lan:
        ipv4_address: 192.168.0.10

  postgres:
    ...  
    networks:
      lan:
        ipv4_address: 192.168.0.11

networks:
  lan:
    ipam:
      driver: default
      config:
        - subnet: "192.168.0.0/24"
          gateway: "192.168.0.1"

Answer 1

192.168.0.255 is broadcast address, so it's not the right way to bind your server on this address.

I expect you run server bind to 0.0.0.0 and from iOS device you should connect to your IP: 192.168.0.17
