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/，它提供了一个简单的 LAMP 堆栈。

我将 Docker 存储库用作 wercker.yml 文件中的框，通过几个简单的步骤来设置我的应用程序，初始化数据库，然后运行我的 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 运行构建时wercker build，它无法连接到 mysql。ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)尝试运行“创建数据库”步骤时，我不断收到以下连接错误。

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

我知道 docker 容器有一个 mysql 连接，因为我可以 ssh 进入它并运行mysql -uroot -e "SHOW DATABASES;"

编辑我当前正在进行的工作 wercker 灯模板可在https://github.com/levi-putna/php-cli-template获得

要求

我知道 wercker.com 相对较新，并且没有很多文档。但我希望有人可以为我提供一个如何在 wercker 测试运行中使用 mysql 的示例。

编辑 - 使用 Wercker 服务

我也尝试使用 Wercker MariaBD 服务进行连接，它不完全是 MySQL，所以不是对我的生产环境的真正测试，但应该足以开始测试。

我更新了 wercker.yml 以添加 mariadb 服务。简化了我让数据库连接工作正常的步骤。

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;"

我似乎仍然遇到与我原来的方法相同的错误。ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

在 wercker 步骤退出后，我还看到了一些额外的日志消息。

您可以使用 Wercker 准备的现成 MySQL 服务器，而不是自己设置。这将确保它在调用之间持续存在。

看看这个文件。

解释

好的，我设法使用@Tal 的建议使数据库连接正常工作。Wercker 码头只提供了一个使用 MariaDB 的示例，幸运的是 MySQL 有一个 docker 容器，其工作方式与 MariaDB 版本几乎完全相同。

我将新容器作为服务添加到我的 wercker.yml。

services:
  - id: mysql

    # 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

然后，我能够在 Wercker 步骤中使用 MySQL 服务公开的环境变量连接到数据库。

  - script:
    name: Create database
    code: mysql -h$MYSQL_PORT_3306_TCP_ADDR -P$MYSQL_PORT_3306_TCP_PORT -uroot -p$MYSQL_ENV_MYSQL_ROOT_PASSWORD -e "CREATE DATABASE IF NOT EXISTS test;"

我还可以使用 PHP 中的环境变量来连接数据库。

class SampleTest extends PHPUnit_Framework_TestCase
{

    public function testSetupWorking()
    {
        $this->assertEquals(true, true);
        $this->assertFalse(false);
    }

    public function testDatabase()
    {

        $hostname = $_SERVER["MYSQL_PORT_3306_TCP_ADDR"];
        $username = 'root';
        $password = $_SERVER["MYSQL_ENV_MYSQL_ROOT_PASSWORD"];
        $database = $_SERVER["MYSQL_ENV_MYSQL_DATABASE"];

        try {
            $dbh = new PDO("mysql:host=$hostname;dbname=$database", $username, $password);
            $this->assertFalse(false);

        } catch (PDOException $e) {
            echo $e->getMessage();
            $this->assertFalse(true, $e->getMessage());
        }
    }

}

我完整的 wercker.yml 看起来像这样，你可以在https://github.com/levi-putna/php-cli-template看到我的完整模板。这只是一个示例，您可能希望清理 PHP 连接到数据库的步骤和方式，但这是一个很好的起点。

答案 - 完整的 wercker.yml

        - id: mysql

          # 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

我已经完成使用以下配置连接到 mysql：

box: ruby:2.1.9
build:
    services:
      - id: mysql
        # your credentials for Docker Hub
        username: $USERNAME

        tag: 5.5.55
        # set the required environment variable
        env:
          MYSQL_ROOT_PASSWORD: roo
          MYSQL_USER: testuser
          MYSQL_PASSWORD: testuser
          MYSQL_DATABASE: testdb
    steps:
      - bundle-install
      - rails-database-yml
      - script:
          name: echo ruby information
          code: |
              echo "ruby version $(ruby --version) running!"
              echo "from location $(which ruby)"
              echo -p "gem list: $(gem list)"
      - script:
          name: Set up db
          code: |
              touch db/schema.rb
              bundle exec rake db:migrate RAILS_ENV=test
      - script:
          name: rspec
          code: bundle exec rspec
