gitlab运行器: mysqld:无法读取'/etc/mysql/conf.d/‘的目录

Question

我在docker中使用gitlab runners。

它使用我们自己的php图片和mysql:5.7图片。它以前是有效的，但现在我们可以在CI作业启动时看到这个错误：

Running with gitlab-runner 10.4.0 (857480b6)

设置变量：

variables:
  MYSQL_DATABASE: test
  MYSQL_ROOT_PASSWORD: password

我应该做什么来调试和解决这个问题？

您需要更改您的docker组成文件，您应该添加privileged: true我的如下所示：

  mysql:
    build: ./DockerFiles/Mysql
    ports:
    - ${LOCAL_PHP_IP}:${MYSQL_PORT}:3306
    privileged: true
    environment:
      MYSQL_ROOT_PASSWORD: root
    volumes:
    - /opt/mysql_data:/var/lib/mysql
