새로운 Docker 컨테이너에서 기존 Django 프로젝트 사용 image: nginx:latest

같은 디렉토리에서 Django 프로젝트를 사용하여 Docker 컨테이너를 시작하려고합니다.

이 자습서 (
https://docs.docker.com/compose/django/#create-a-django-project )에 따라 사용할 수 있습니다

docker-compose run web django-admin startproject newproject .

docker-compose.yml에 정의 된 docker 컨테이너 내부에서 프로젝트를 시작하려면

version: '3'

services:
  db:
    image: postgres
  web:
    build: .
    #command: python3 manage.py runserver 0.0.0.0:8000
    command: bash -c "python manage.py makemigrations && python manage.py migrate && gunicorn things.wsgi -b 0.0.0.0:8000"
    volumes:
      - .:/code
    expose:
      - "8000"
    depends_on:
      - db
  nginx:
    image: nginx:latest
    container_name: NGINXDOCKERNAME
    ports:
      - "8000:8000"
    volumes:
      - .:/code
      - ./config/nginx:/etc/nginx/conf.d
    ports:
      - "8000:8000"
    depends_on:
      - web

및 dockerfile

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

django-admin startproject newproject를 어떻게 사용합니까? 컨테이너 외부에서 (즉, docker-machine 명령 줄에서) 프로젝트를 컨테이너에 복사합니까?

이제 컨테이너 내부에서 프로젝트를 시작하면 서버가 시작되고 올바른 포트에서 프로젝트를 볼 수 있지만 컨테이너 외부에서 프로젝트를 시작하면 (하지만 동일한 디렉토리에서 로컬로) 웹 및 nginx 컨테이너가 올바르게 시작되지 않습니다.

Windows 10 버전 1709에서 도커 머신을 실행 중입니다.

웹 컨테이너 시작의 출력은 아래에 있으며 요청시 서버의 출력이 이어집니다.

답변

귀하의 질문에 대한 답변은 https://docs.docker.com/compose/django/#connect-the-database 에서 찾을 수 있습니다 . 링크에 설명 된대로 데이터베이스를 실제로 설정하면 DATABASE 구성이 다음과 같이됩니다.

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

아무 문제가 없을 것입니다.

listen_addresses = '*'vim을 사용하여 설정할 수도 있습니다 . 이에 대한 자세한 내용은 http://www.mozmorris.com/2011/11/15/configure-postgresql-to-accept-tcpip-connections.html 링크를 시도하십시오.
