我的django应用程序无法连接到postgresql . 我正在使用Dockerfile进行django并使用docker-compose和postgres官方图像进行构建 .
泊坞窗，compose.yml
version: '2'
services:
db:
image: eg_postgresql
expose:
- 5432
environment:
- POSTGRES_PASSWORD=docker
- POSTGRES_USER=docker
- POSTGRES_DB=postgres
web:
build: .
command: python3 manage.py runserver 0.0.0.0:8000
volumes:
- .:/test_application
ports:
- "8000:8000"
links:
- "db:db"
environment:
- DATABASE_URL=postgres://docker:docker@db:5432/postgres
- DJANGO_SECRET_KEY=x7-g-xu^h5k%h8860!7ksn=@)7q9frn9_l6tmefvf)y=0)d!uh
输出：
conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
django.db.utils.OperationalError: could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?
could not connect to server: Cannot assign requested address
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5432?
docker-compose ps
ubuntu@ip-172-31-7-117:~/dj1/helloworld$ sudo docker-compose ps
Name Command State Ports
----------------------------------------------------------------------------------
helloworld_db_1 /usr/lib/postgresql/9.3/bi ... Up 5432/tcp
helloworld_web_1 python3 manage.py runserve ... Up 0.0.0.0:8000->8000/tcp
在app settings.py中
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'postgres',
'USER': 'docker',
'PASSWORD': 'docker',
'HOST': 'db',
'PORT': '5432',
}
}
我试过很多方法来连接，但问题是一样的......

尝试替换公开： - 5432用于带端口的数据库服务 - "5432:5432"
