Docker connect host mysql for django

I am trying to connect to my host mysql from docker container but I don't know how to connect. I have a django project for that I followed Django Docker I am using this tutorial this one is working fine for djnago and postgres.

I am using mac and I am using mamp server I want to connect my djnago app to my host mysql.

My docker file code is:

    FROM python:3
    ENV PYTHONUNBUFFERED 1
    RUN mkdir /code
    WORKDIR /code
    ADD requirements.txt /code/
    RUN pip install -r requirements.txt
    ADD . /code/

And my docker compose file is:

 version: '3'

services:
  db:
    image: postgres
  web:
    build: .
    command: python3 manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    depends_on:
      - db

This one is working fine but I am trying to connect my django app to my host mysql.

I don't know how to connect host mysql from my docker.

I think you can use "host.docker.internal" host if you are using mac. But this is only for development in your machine only

first with bellow command create a network named hostnetwork to have fixed host ip inside containers

docker network create -d bridge --subnet 192.168.0.0/24 --gateway 192.168.0.1 hostnetwork

then change your docker-compose config to connect your containers to hostnetwork

services:
    db:
        image: image_name
        networks:
            - hostnetwork
networks:
    hostnetwork:
        external: true

now you can set django admin db config to your host mysql engine like bellow sample:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'db_name',
        'USER': 'username',
        'PASSWORD': '',
        'HOST': '192.168.0.1',
        'PORT': '3306'
    }
}
