Django 服务器启动不上 docker-compose

Question

我将我的 django 后端应用程序码头化。 我正在使用 posgresql 作为数据库。 在做 docker-compose 之后，最后的日志是：

db_1       | 2021-12-21 18:39:58.213 UTC [1] LOG:  listening on IPv4 address "0.0.0.0", port 5432
db_1       | 2021-12-21 18:39:58.213 UTC [1] LOG:  listening on IPv6 address "::", port 5432
db_1       | 2021-12-21 18:39:58.310 UTC [1] LOG:  listening on Unix socket "/var/run/postgresql/.s.PGSQL.5432"
db_1       | 2021-12-21 18:39:58.476 UTC [42] LOG:  database system was shut down at 2021-12-21 18:39:58 UTC
db_1       | 2021-12-21 18:39:58.678 UTC [1] LOG:  database system is ready to accept connections

我没有收到任何其他日志，我不知道问题可能是由于 postgresql 引起的。 但是 django 服务器没有启动。 我做了 docker ps 我得到了以下结果

CONTAINER ID   IMAGE                    COMMAND                  CREATED          STATUS          PORTS                                       NAMES

我认为容器已启动，但 Django 服务器仍未启动可能是什么问题？

docker-compose.yml

version: "3.9"

services:
  db:
    image: postgres:11.2-alpine
    volumes:
      - ./postgres-data:/var/lib/postgresql/data
    environment:
      - HOST=localhost
      - POSTGRES_DB=prodler
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=admin123
    ports:
      - 5432:5432
  prodler:
    build:
      context: .
      dockerfile: Dockerfile
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    depends_on:
      - db

您需要在配置中更改连接详细信息以连接到 postgres:5432
