mysql - 如何在 docker-compose.yml 中使用多行命令标志配置 MySQL 实例

Question

我想使用 docker 镜像启动 MySQL 本地实例。

到目前为止，我的 docker-compose.yml 文件如下所示:

version: '3.3'

services:
   db:
     image: mysql:8
     command: --default-authentication-plugin=mysql_native_password
     volumes:
       - ./mysql-dump:/docker-entrypoint-initdb.d
     restart: always
     environment:
       MYSQL_ROOT_PASSWORD: admin
       MYSQL_DATABASE: sqlPractice
       MYSQL_USER: admin
       MYSQL_PASSWORD: admin
     ports:
      - '7142:3306'
     security_opt:
      - seccomp:unconfined

到目前为止，一切正常。我的数据库提供了数据，但在执行一次查询后，如:

SELECT DISTINCT surname, name, data FROM exams e JOIN students s ON e.`id-student` = s.`id-student` WHERE passed='Y' AND (data, `id-centre`) = (SELECT MIN(data), e.`id-centre` FROM exams e JOIN centers c ON e.`id-center` = c.`id-center` WHERE e.passed='Y' AND c.`center-name` = 'IT Institute') 

我收到如下错误:

ER_MIX_OF_GROUP_FUNC_AND_FIELDS: In aggregated query without GROUP BY, expression #2 of SELECT list contains nonaggregated column 'sqlPractice.e.id-center'; this is incompatible with sql_mode=only_full_group_by

根据这篇文章: click 我想在我的 docker-compose.yml 中设置一个参数 sql_mode 因为据称这会解决一个问题。

我的 docker-compose.yml 在命令标志中有两个参数看起来像:

version: '3.3'

services:
   db:
     image: mysql:8
     command: 
       - default-authentication-plugin=mysql_native_password 
       - sql_mode=""
     volumes:
       - ./mysql-dump:/docker-entrypoint-initdb.d
     restart: always
     environment:
       MYSQL_ROOT_PASSWORD: admin
       MYSQL_DATABASE: sqlPractice
       MYSQL_USER: admin
       MYSQL_PASSWORD: admin
     ports:
      - '7142:3306'
     security_opt:
      - seccomp:unconfined

但毕竟我在启动时收到错误

db_1  | /usr/local/bin/docker-entrypoint.sh: line 363: exec: default-authentication-plugin=mysql_native_password: not found

毕竟容器不能正常工作。

我想要实现的是通过 docker-compose.yml 配置 MySQL 实例，这两个参数在 command param in docker-compose.yml 使我的查询按预期工作。

对于如何实现目标的建议，我将不胜感激。

services:
  db:
    image: mysql:8
    command: ['--sql_mode=', '--default-authentication-plugin=mysql_native_password']
