使用 Pycharm 调试时如何让 Docker-compose 运行所有服务？

Question

我有一个简单的 dockerized Django gunicorn、nginx 和 postgress 项目（每个都是一个服务）。

当我使用 docker-compose up 运行它时，一切正常：

maximd@ubuntu ~/PycharmProjects/MyQ (master) $ docker-compose ps

     Name                    Command               State          Ports        
-------------------------------------------------------------------------------
myq_database1_1   docker-entrypoint.sh postgres    Up      5432/tcp            
myq_djangoapp_1   /bin/sh -c gunicorn --bind ...   Up      8000/tcp            
myq_nginx_1       nginx -g daemon off;             Up      0.0.0.0:8000->80/tcp

但是，当我使用 pycharm 调试器午餐时，它不会运行 nginx。

我怀疑由于 djangoapp 依赖于我的 docker-compose.yml 文件中的数据库服务，它只是创建了它们，但它不运行 nginx。

这是我在调试器中使用 pycharm 运行它后看到的：

maximd@ubuntu ~/PycharmProjects/MyQ (master) $ docker-compose ps
     Name                    Command               State                  Ports               
----------------------------------------------------------------------------------------------
myq_database1_1   docker-entrypoint.sh postgres    Up       5432/tcp                          
myq_djangoapp_1   python -u /opt/.pycharm_he ...   Up       0.0.0.0:55488->55488/tcp, 8000/tcp
myq_nginx_1       nginx -g daemon off;             Exit 0                                     

所以，我的问题是：有没有办法让 nginx 也成为 djangoapp 的依赖项？有没有办法让 pycharm 运行所有服务，而不仅仅是我要调试的服务？

这是我的 docker-compose.yml 文件：

version: '3'

services:

  djangoapp:
    build: .
    volumes:
      - .:/services/djangoapp
      - static_volume:/services/djangoapp/static
      - media_volume:/services/djangoapp/media
    networks:
      - nginx_network
      - database1_network
    depends_on:
      - database1

  nginx:
    image: nginx:1.13
    ports:
      - 8000:80
    volumes:
      - ./config/nginx/conf.d:/etc/nginx/conf.d
      - static_volume:/services/djangoapp/static
      - media_volume:/services/djangoapp/media
    depends_on:
      - djangoapp
    networks:
      - nginx_network

  database1:  # <-- IMPORTANT: same name as in DATABASES setting, otherwise Django won't find the database!
    image: postgres:10
    env_file:
      - config/db/database1_env
    networks:
      - database1_network
    volumes:
      - database1_volume:/var/lib/postgresql/data

networks:
  nginx_network:
    driver: bridge
  database1_network:
    driver: bridge

volumes:
  database1_volume:
  static_volume:
  media_volume:

这是我在图片中的调试配置和解释器配置。

终于解决了，解决方法是将docker-compose.yml改成这个：

version: '3'

services:

  djangoapp:
    build: .
    restart: always
    volumes:
      - .:/services/djangoapp
      - static_volume:/services/djangoapp/static
      - media_volume:/services/djangoapp/media
    networks:
      - nginx_network
      - database1_network
    depends_on:
      - database1
      - nginx

  nginx:
    image: nginx:1.13
    restart: always
    ports:
      - 8000:80
    volumes:
      - ./config/nginx/conf.d:/etc/nginx/conf.d
      - static_volume:/services/djangoapp/static
      - media_volume:/services/djangoapp/media
    networks:
      - nginx_network

  database1:  # <-- IMPORTANT: same name as in DATABASES setting, otherwise Django won't find the database!
    image: postgres:10
    env_file:
      - config/db/database1_env
    networks:
      - database1_network
    volumes:
      - database1_volume:/var/lib/postgresql/data

networks:
  nginx_network:
    driver: bridge
  database1_network:
    driver: bridge

volumes:
  database1_volume:
  static_volume:
  media_volume:

基本上让djangoapp依赖于nginx，并在nginx和djangoapp中添加restart:always。

也在运行/调试配置窗口中：

主机是：0.0.0.0

工作目录：/services/djangoapp（就像djangoapp里面的那个）

路径映射：/home/maximd/PycharmProjects/MyQ=/services/djangoapp

我怀疑你的 nginx 容器自己崩溃了，看看docker logs myq_nginx_1
