mysql - Docker-compose 在 CircleCI 中复制 MySQL 配置时出现问题

Question

以下内容在本地计算机上运行良好，但在 checkin CircleCI 时失败:

mysql:
  image: mysql:5.7
  ports:
    - 3306:3306
  environment:
    - MYSQL_ALLOW_EMPTY_PASSWORD=true
    - MYSQL_ROOT_HOST=%
  restart: always
  volumes:
    - ./docker/mysql/mysqld.cnf:/etc/mysql/conf.d/mysql.cnf

checkout 的项目下有./docker/mysql/mysqld.cnf文件。

CircleCi 上显示的错误是:

ERROR: for proj-server_mysql_1 Cannot start service mysql: b'oci runtime error: container_linux.go:265: starting container process caused "process_linux.go:368: container init caused \"rootfs_linux.go:57: mounting \\\"/home/circleci/max/proj-server/docker/mysql/mysqld.cnf\\\" to rootfs \\\"/var/lib/docker/aufs/mnt/4a9af90d342b491ae92af5a88360d2e34fce0d21c15f8a648767e89fb51aa\\\" at \\\"/var/lib/docker/aufs/mnt/4a9af90d342b491ae92af5a88360d2e34fce0d21c15f8a648767e89fb51aa/etc/mysql/conf.d/mysql.cnf\\\" caused \\\"not a directory\\\"\""\n: Are you trying to mount a directory onto a file (or vice-versa)?

It's not possible to use volume mounting with the docker executor, but with using the machine executor it's possible to mount local directories to your running Docker containers. You can learn more about the machine executor here on our docs page.
