Django 失败的 CI/CD 管道

Question

我的 gitlab ci 管道不断失败。似乎被困在这里。实际上我对 CI 的东西还是新手，所以我不知道做错了什么。任何帮助将不胜感激以下是 .gitlab-ci.yml 文件

image: python:latest

services:
  - postgres:latest

variables:
  POSTGRES_DB: thorprojectdb
  POSTGRES_PASSWORD: $''
  POSTGRES_USER: $majesty
  POSTGRES_HOST_AUTH_METHOD: trust

# This folder is cached between builds
# http://docs.gitlab.com/ee/ci/yaml/README.html#cache
cache:
  paths:
    - ~/.cache/pip/

before_script:
  - python -V

connect:
  image: postgres
  script:
  # official way to provide password to psql: http://www.postgresql.org/docs/9.3/static/libpq-envars.html
  - export PGPASSWORD=$POSTGRES_PASSWORD
  - psql -h "postgres" -U "$POSTGRES_USER" -d "$POSTGRES_DB" -c "SELECT 'OK' AS status;"

build:
  stage: build
  script:
  - pip install -r requirements.txt
  - python manage.py migrate
  only:
    - EC-30

在我的 settings.py 文件中，我有以下设置

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'projectdb',
        'HOST': 'postgres',
        'PASSWORD': ''
    }
}

但是当我推送到 gitlab 时，构建过程一直失败。 - pip install -r requirements.txt 运行完美，但一旦到达 - python manage.py migrate，它就会失败。以下是我得到的错误

django.db.utils.OperationalError: could not connect to server: No such file or directory
    Is the server running locally and accepting
    connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
Cleaning up project directory and file based variables
ERROR: Job failed: exit code 1

分析.gitlab-ci.yml文件的描述，很明显你在文件（POSTGRES_DB）中声明了数据库，但是你缺少与凭据相关的信息，DB_USER， DB_PASS，如下面的链接所述：

gitlab-config-postgres

请记住，最好在存储库的 CI/CD 部分使用声明变量。欲了解更多信息：

ci-cd-gitlab-variables

带有配置示例的存储库：

repository-example-gitlab-postgres

services:
  - postgres

variables:
  # Configure postgres service (https://hub.docker.com/_/postgres/)
  POSTGRES_DB: custom_db
  POSTGRES_USER: custom_user
  POSTGRES_PASSWORD: custom_pass

connect:
  image: postgres
  script:
  # official way to provide password to psql: http://www.postgresql.org/docs/9.3/static/libpq-envars.html
  - export PGPASSWORD=$POSTGRES_PASSWORD
  - psql -h "postgres" -U "$POSTGRES_USER" -d "$POSTGRES_DB" -c "SELECT 'OK' AS status;"
