Django server not running from docker-compose?

Question

Django

I'm trying to run a django application through docker with a base on postgres
docker-compose.yml:

version: '3.7'

services:
    db:
        image: postgres:latest
        environment: 
            POSTGRES_PASSWORD: 'password'
        volumes:
            - postgres_data:/var/lib/postgresql/data/
    web:
        build: .
        command: python /usr/src/dm_rest/manage.py runserver 0.0.0.0:8000
        volumes:
            - .:/usr/src/dm_rest
        ports: 
            - 8000:8000
        depends_on:
            - db
volumes: 
    postgres_data:

Dockerfile

FROM python:3.8

ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

WORKDIR /usr/src/dm_rest

COPY ./req.txt /usr/src/dm_rest
RUN pip install -r /usr/src/dm_rest/req.txt

COPY . /usr/src/dm_rest/

settings.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'postgres',
        'USER': 'postgres',
        'PASSWORD': 'password',
        'HOST': 'db',
        'PORT': '5432',
    }
}

As a result, the answer from postgres is this:

And dzhanga refuses to start the server


. What is written incorrectly?

Answer 1

In general, for some reason, the server was not at 127.0.0.1:8000, but at the ip of the virtual machine

Answer 2

I would start by checking that Popstgres is running and that the database is correct.
