GitLab CI-使用Mysql服务

我尝试在symfony的web项目上使用GitLab CI

要执行一些测试，我需要有一个数据库并从应用程序访问它，但它不起作用。似乎无法访问mysql服务。。。实际上，我只是在

gitlab ci.yml

文件的顶部声明服务，并设置变量来配置它。是否有可能将该服务链接到我自己的应用程序服务以使用它

My gitlab-ci.yml：

image: docker:latest

services:
- docker:dind
- name: mysql:5.7.21
  alias: db

stages:
- build
- test
- release

variables:
  MYSQL_ROOT_PASSWORD: collection-manager
  MYSQL_USER: collection-manager
  MYSQL_PASSWORD: collection-manager
  MYSQL_DATABASE: collection-manager
  CONTAINER_IMAGE: registry.gitlab.com/$CI_PROJECT_PATH
  CONTAINER_TEST_IMAGE: registry.gitlab.com/$CI_PROJECT_PATH:$CI_COMMIT_REF_NAME
  CONTAINER_RELEASE_IMAGE: registry.gitlab.com/$CI_PROJECT_PATH:latest
  DOCKER_DRIVER: overlay2

before_script:
- docker login -u gitlab-ci-token -p $CI_JOB_TOKEN registry.gitlab.com

build:
  stage: build
  script:
    - docker pull $CONTAINER_RELEASE_IMAGE || true
    - docker build --cache-from $CONTAINER_RELEASE_IMAGE -t $CONTAINER_TEST_IMAGE .
    - docker push $CONTAINER_TEST_IMAGE

cs-test:
  stage: test
  script:
    - docker pull $CONTAINER_TEST_IMAGE
    - docker run $CONTAINER_TEST_IMAGE bash -c "composer install --no-progress --no-suggest --optimize-autoloader --no-interaction; ./vendor/bin/php-cs-fixer fix --diff --dry-run -v"
    - docker run $CONTAINER_TEST_IMAGE bash -c "composer install --no-progress --no-suggest --optimize-autoloader --no-interaction; ./bin/console lint:yaml app"
    - docker run $CONTAINER_TEST_IMAGE bash -c "composer install --no-progress --no-suggest --optimize-autoloader --no-interaction; ./bin/console lint:twig app/Resources"
    - docker run $CONTAINER_TEST_IMAGE bash -c "composer install --no-progress --no-suggest --optimize-autoloader --no-interaction; composer validate --strict"

release-image:
  stage: release
  script:
    - docker pull $CONTAINER_TEST_IMAGE
    - docker tag $CONTAINER_TEST_IMAGE $CONTAINER_RELEASE_IMAGE
    - docker push $CONTAINER_RELEASE_IMAGE
  only:
    - master

在job cs测试中，我得到如下回报：

docker run $CONTAINER_TEST_IMAGE bash -c "composer install --no-progress --no-suggest --optimize-autoloader --no-interaction; ./vendor/bin/php-cs-fixer fix --diff --dry-run -v"

我不明白为什么。。。应用程序在以下位置具有默认连接：

- host: db
- db name: collection-manager
- db user: collection-manager
- db pass: collection-manager

在我使用MySQL进行集成测试的项目中，我有以下环境变量：

MYSQL_USER: 'your_user'
MYSQL_PASSWORD: 'your_pass'
MYSQL_HOST: 'mysql__mysql-server'
MYSQL_PORT: 3306
MYSQL_DATABASE_NAME: 'testdb'
MYSQL_DATABASE: 'testdb'
MYSQL_ROOT_HOST: '%'
MYSQL_ROOT_PASSWORD: 'your_rootpw'

---

我记得我花了很多时间来计算主机名，我发现您的配置中也缺少它。

将网络模式设置为主机（在macOS下不起作用），并添加自定义主机到IP映射：

services:
  - docker:dind
  - mysql:5.7
script:
  - export # just for debugging
  - docker build --network=host --add-host mysql:${MYSQL_PORT_3306_TCP_ADDR} .
