MongoDB 服务器不会使用 gitlab-ci 从 gitlab 运行程序启动

Question

现在我正在使用 Ruby 和 Mongo 开发应用程序。 但是当我使用 gitlab-ci 部署应用程序时我陷入了困境，其中 mongo 服务器似乎没有在 gitlab runner 的测试环境中启动。

这是我的 gitlab-ci.yml

stages :
- test
- deploy

services:
  - mongo:latest

unitTest:API:
  image: ruby:2.6.10
  stage: test
  cache: 
    paths:
      - API/vendor/
  before_script:
    - ruby -v
    - gem install bundler --no-ri --no-rdoc
    - bundle install --gemfile=API/Gemfile --path vendor
  script:
    - RAILS_ENV=test rspec API/spec
    - RAILS_ENV=test rubocop API
  artifacts:
    paths:
      - coverage/

deploy_coba:
  stage: deploy
  before_script:
    - cd API
  script: 
    - gem install dpl
    - dpl --provider=heroku --app=exhibisi-cobacoba --api-key=68b12c2b-cfbc-4478-b943-f26552fb907e
  only:
    - coba_coba

staging:
  stage: deploy
  before_script:
    - cd API
  script: 
    - gem install dpl
    - dpl --provider=heroku --app=exhibisi-staging --api-key=68b12c2b-cfbc-4478-b943-f26552fb907e
  only:
    - sit_uat

production:
  stage: deploy
  before_script:
    - cd API
  script:
    - gem install dpl
    - dpl --provider=heroku --app=exhibisi-prod --api-key=68b12c2b-cfbc-4478-b943-f26552fb907e
  only:
    - master

pages:
  stage: deploy
  script:
    - mv coverage/ public/
  artifacts:
    paths:
      - public
    expire_in: 30 days

这是 gitlab runner 错误的结果

这是我的 mongoid.yml 文件：

development:
  options:
    raise_not_found_error: false
  clients:
    default:
      database: mongoid_dev
      hosts:
        - localhost:27017
test:
  options:
    raise_not_found_error: false
  clients:
    default:
      database: mongoid_dev
      hosts:
        - localhost:27017

谁能告诉我我错过了什么。 我到处搜索有关 gitlab-ci 和数据库的信息，但只有 mysql 和 postgre sql 显示了这一点。 我错过了在测试中运行 mongo 服务器吗？ 或者我应该从代码本身运行服务器。 或者这是另一个问题？

Answer 1

您的 MongoDB 很可能在 GitlabCI 上运行，但它在单独的 Docker 容器中执行。 必须使用mongo:27017而不是localhost:27017从测试中访问它。

在这里查看： https : //docs.gitlab.com/ee/ci/docker/using_docker_images.html#accessing-the-services

所以你应该适当地修复你的配置（mongoid.yml）。

Answer 2

问题出在 MongoDB 数据库的连接字符串上。 由于您使用了 mongo 服务，并且没有放置别名，因此 Gitlab 将“mongo”作为其主机名。 根据 Gitlab：服务主机名的默认别名是根据以下规则从其映像名称创建的：

• 冒号 (:) 之后的所有内容都被删除。
• 斜线 (/) 替换为双下划线 (__) 并创建主别名。
• 斜线 (/) 替换为单个破折号 (-) 并创建辅助别名（需要 GitLab Runner v1.1.0 或更高版本）。

因此，您必须使用mongo:27017而不是 localhost

Your connection string will be like: mongodb://mongo:27017/${databaseName}
