在Ubuntu中通过docker-compose部署MySQL时无法部署；docker-compose.yml文件如下：
version: '3'
services:
mysql:
restart: always
image: mysql:8.2
network_mode: bridge
container_name: mysql
environment:
MYSQL_ROOT_PASSWORD: root123
command:
--character-set-server=utf8mb4
--collation-server=utf8mb4_general_ci
--explicit_defaults_for_timestamp=true
--lower_case_table_names=1
--max_allowed_packet=128M
volumes:
- /etc/localtime:/etc/localtime:ro
- /data/docker/mysql/mysql:/var/lib/mysql
- /data/docker/mysql/etc:/etc/mysql:ro
ports:
- 3306:3306
我的步骤如下：
1.注释挂载，直接启动mysql 成功
2.复制容器中的/var/lib/mysql到宿主机我希望挂载的地方
3.复制/etc/mysql ，然后编写my.cnf放到宿主机/data/docker/mysql/etc/mysql/conf.d下
4.删除镜像
5.打开注释
错误如下：
