切换到 postgresql 后 - 连接被对等重置

Question

根据this教程我切换到postgresql代码。

# django_project/settings.py
DATABASES = {
    "default": {
        "ENGINE": "django.db.backends.postgresql",
        "NAME": "postgres",
        "USER": "postgres",
        "PASSWORD": "postgres",
        "HOST": "db",  # set in docker-compose.yml
        "PORT": 5432,  # default postgres port
    }
}

这里是

docker-compose.yml

# docker-compose.yml
version: "3.9"

services:
  web:
    build: .
    command: python /code/manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - 8000:8000
    depends_on:
      - db
  db:
    image: postgres:13
    volumes:
      - postgres_data:/var/lib/postgresql/data/
    environment:
      - "POSTGRES_HOST_AUTH_METHOD=trust"

volumes:
  postgres_data:

编辑

DATABASES

部分之前一切正常。

当我跑步时

$ curl 127.0.0.1:8000
curl: (56) Recv failure: Connection reset by peer

尝试使用数据库凭据 -

# docker-compose.yml
version: "3.9"

services:
  web:
    build: .
    command: python /code/manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - 8000:8000
    depends_on:
      - db
  db:
    image: postgres:13
    volumes:
      - postgres_data:/var/lib/postgresql/data/
    environment:
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=postgres
      - POSTGRES_DB=postgres

volumes:
  postgres_data:

你可以使用 env 文件 -

db:
    image: postgres:13
    volumes:
      - postgres_data:/var/lib/postgresql/data/
    env_file:
      - ./.env.dev.db

这里是环境

#.env.dev.db
POSTGRES_USER=hello_django
POSTGRES_PASSWORD=hello_django
POSTGRES_DB=hello_django_prod
