Question

我想用gitlab ci中的mongo db访问来测试我的nodejs应用程序。因此，我设置了mongo服务并尝试连接到它。 Docs说，应该可以通过主机名访问它。但似乎我的应用程序找不到mongo服务。显式地图端口有可能吗？由于Dockerimage公开了27017，但我不知道gitlab的作用是什么。

.gitlab-ci.yml

test:
  stage: test
  image: docker:latest
  services:
    - docker:dind
    - mongo:latest
  variables:
    MONGO_INITDB_ROOT_USERNAME: test
    MONGO_INITDB_ROOT_PASSWORD: test
  before_script:
    - docker build -t app -f Dockerfile.test .
  script:
    - docker run app  npm run test

错误

您可以为mongo服务的主机名配置别名：

services:
  - name: docker:dind
  - name: mongo:latest
    alias: mongo

否则，您可以转发您的mongo端口：

  before_script:
    - apt install -y socat 
    - socat tcp-listen:27017,fork tcp:mongo:27017 &
    - docker build -t app -f Dockerfile.test .
