wercker.com连接到MySQL数据库

背景

我正在尝试使用http://wercker.com为Yii2应用程序构建一些自动化测试.我创建了自己的Docker存储库https://hub.docker.com/r/consynki/yii2/,该存储库提供了一个简单的LAMP堆栈.

我将Docker存储库用作wercker.yml文件中的框,并通过一些简单的步骤来设置我的应用,初始化数据库,然后运行phpunit测试

box: consynki/yii2

build:
  steps:

- script:
    name: Update enviroment dependencies
    code: |-
      curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/bin/ --filename=composer

- script:
    name: Install Composer dependencies
    code: |-
      rm -rf ./vendor
      /usr/bin/composer install --no-interaction --prefer-source

- script:
    name: Apache site install
    code: |-
      sudo chmod -R 755 /var/www
      sudo cp -r ./ /var/www/example.lan/
      sudo chown -R $USER:$USER /var/www/example.lan/
      sudo cp ./config/example.lan.conf /etc/apache2/sites-available/example.lan.conf
      sudo a2ensite example.lan.conf
      sudo cp -fr ./config/hosts /etc/hosts
      sudo service apache2 restart

- script:
    name: Create database
    code: |-
      mysql -uroot -e "SHOW DATABASES;"
      mysql -uroot -e "CREATE DATABASE IF NOT EXISTS test"

- script:
    name: PHPUnit integration tests
    code: |-
      ./vendor/bin/phpunit --configuration phpunit.xml

问题

问题是,当我使用wercker CLI wercker构建运行我的构建时,它无法连接到mysql.我不断收到以下连接错误ERROR 2002(HY000)：尝试运行“创建数据库”步骤时,无法通过套接字’/var/run/mysqld/mysqld.sock'(2)连接到本地MySQL服务器.

 - script:
    name: Create database
    code: |-
      mysql -uroot -e "SHOW DATABASES;"
      mysql -uroot -e "CREATE DATABASE IF NOT EXISTS test"

我知道docker容器具有mysql连接,因为我可以SSH进入它并运行mysql -uroot -e“ SHOW DATABASES;”.

编辑我当前进行中的巫师灯模板可在https://github.com/levi-putna/php-cli-template获得

请求

我知道wercker.com相对较新,并且没有很多文档.但我希望有人能提供一个示例,说明如何在wercker测试运行中使用mysql.

编辑-使用Wercker服务

我还尝试使用Wercker MariaBD服务进行连接,因为它并非完全是MySQL,因此不是对我的生产环境的真实测试,但应该足以开始测试.

我更新了wercker.yml以添加mariadb服务.简化了使数据库连接正常工作的步骤.

box: consynki/yii2

services:
    - id: mariadb

      # your credentials for Docker Hub
      username: $USERNAME
      password: $PASSWORD
      tag: latest

      # set the required environment variable
      env:
        MYSQL_ROOT_PASSWORD: mypassword
        MYSQL_DATABASE: test_database
        MYSQL_USER: admin
        MYSQL_PASSWORD: test123

build:

  steps:

    - script:
        name: Create database
        code: |-
          mysql -h $MARIADB_PORT_3306_TCP_ADDR -P $MARIADB_PORT_3306_TCP_PORT -u $MYSQL_USER -p test123 -v
          mysql -h $MARIADB_PORT_3306_TCP_ADDR -P $MARIADB_PORT_3306_TCP_PORT -u $MYSQL_USER -p test123 -e "SHOW DATABASES;"

我似乎仍然遇到与原始方法相同的错误.错误2002(HY000)：无法通过套接字’/var/run/mysqld/mysqld.sock'(2)连接到本地MySQL服务器

在wercker步骤退出后,我还看到了一些其他日志消息.

最佳答案

您可以使用由Wercker准备的现成的MySQL服务器,而不用自行设置.这将确保它在两次调用之间仍然存在.
