Question

我正在为我的Django项目设置位桶管道，以便能够运行一些自动测试。我正在使用默认的python Docker映像和postgres docker映像作为服务，但是Django无法连接到PostgreSQL服务器。无论我尝试什么，我总是会收到错误消息：

psycopg2.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?

我尝试在Django设置文件中设置带有或不带有端口5432的localhost / posgres映像名称。还以为图像可能没有暴露端口。

我的bitbucket管道文件

# This is a sample build configuration for Python.
# Check our guides at https://confluence.atlassian.com/x/x4UWN for more examples.
# Only use spaces to indent your .yml configuration.
# -----
# You can specify a custom docker image from Docker Hub as your build environment.
image: python:3.7.3

definitions:
  services:
    postgres:
      image: postgres
      environment:
        POSTGRES_DB : 'my_db'
        POSTGRES_USER : 'my_user'
        POSTGRES_PASSWORD: 'my_pwd'
      expose:
        - "5432"
      ports:
        - "5432:5432"

pipelines:
  default:
    - step:
        caches:
          - pip
        script: # Modify the commands below to build your repository.
          - pip install -r requirements.txt
          # Run tests
          - python manage.py test --keepdb
      services:
        - postgres

我的Django数据库设置

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'my_db',
        'USER': 'my_user',
        'PASSWORD': 'my_pwd',
        'HOST': 'localhost',
        'PORT': '',
    },
    'TEST': {
        'NAME': 'my_db',
        'CHARSET': 'UTF8',
        'HOST': 'postgres',
        'PORT': '5432'
    },
}

我希望我的管道能够连接到运行posgresql的postgres映像。

无法为我的django项目从bitbucket管道中的python docker image连接到postgres docker image
