Only Django inside docker container and local database(postgres) is not in container

Create django project with localhost database

Acutally, this is example of my Dockerfile and docker-compose.yml. I worked on mac OS. I would like to run my django app inside docker container, but I didn't want to use container with postgres db inside docker. I have already installed and running postgres instance with all data I need. So django is in container, postgres is out.

• My Dockerfile:

FROM python:3.8-alpine
ENV PYTHONDONTWRITEBYTECODE=1
ENV PYTHONUNBUFFERED=1
WORKDIR /code
COPY requirements.txt /code/
RUN pip install -r requirements.txt
COPY . /code/

Nothing special here. Just create app, running requirements for environment.

• My docker-compose.yml:

version: "3.8"

services:
  web:
    build: .
    command: >
      sh -c "python manage.py migrate &&
             python manage.py runserver 0.0.0.0:8000"
    volumes:
      - .:/code
    ports:
      - "8008:8000"
    environment:
      - DB_NAME=YOUR_DB_NAME_HERE
      - DB_USER=YOUR_DB_USER_HERE
      - DB_PASSWORD=YOUR_DB_PASSWORD_HERE
      - DB_HOST=docker.for.mac.localhost

For me all magic was in line with docker.for.mac.localhost.
