Gitlab Django CI/CD postgres: 连接被拒绝

Gitlab Django CI/CD postgres: Connection refused

错误

我在使我的 Django CI/CD 工作时遇到了很多麻烦。 我正在使用 Django + postgres,我的测试用例都通过了,但我想实现持续集成。 请注意,以下输出 来自 Gitlab Runner.

我不断收到此错误:(... 是我遗漏了一些细节的地方,但它只是回溯或命名有关我的项目的特定内容等)

$ cd src
$ python manage.py makemigrations

配置文件

.gitlab-cl.yml

image: python:latest

services:
  - postgres:latest
variables:
  POSTGRES_DB: postgres
  POSTGRES_HOST: postgres
  POSTGRES_USER: postgres
  POSTGRES_PASSWORD: postgres

cache:
  paths:
    - ~/.cache/pip/

before_script:
  - python -V  # Print out python version for debugging
  - pip install -r requirements.txt

test:
  script:
    - python manage.py makemigrations
    - python manage.py migrate
    - python manage.py test --settings mysite.cicd_settings

settings.py

如您所见,我为 运行 我的测试指定了一个不同的设置文件 cicd_settings

from mysite.settings import *

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'postgres',
        'USER': 'postgres',
        'PASSWORD': 'postgres',
        'HOST': 'postgres',
        'PORT': '5432',
   },
}

它继承了我的普通 settings.py 文件的所有内容,但覆盖了数据库设置。

尝试过的解决方案

我尝试了以下解决方案:

Postgres Gitlab教程: https://docs.gitlab.com/ee/ci/services/postgres.html

类似的 Whosebug 问题:

使用 dj_database_url 包:

Django Gitlab 的默认设置 CI/CD https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/ci/templates/Django.gitlab-ci.yml

如您所见,我使用了非常简单的测试设置,但仍然无法正常工作。

脚本在 python manage.py makemigrations 行失败,因为您没有为它指定 --settings。但实际上,您甚至不需要为测试手动 运行 迁移 - 它会由测试 运行 自动完成,到测试数据库。

所以从测试块中删除 python manage.py makemigrationspython manage.py migrate,它应该 运行 成功。

此外,您永远不会希望 运行 makemigrations 自动。它是用于开发的工具,生成的迁移将包含在 VCS 中 (git)。
