docker-compose启动mysql一直提示挂载目录存在文件

version: "3.8"
services:
  mysql:

    container_name: mysql

 上面的docker-compose.yml启动一直报错，实际挂载目录是干净的。

 解决方法，怀疑dokcer一直在使用什么缓存，读取旧的容器信息，存在脏数据

解决方法：

# 停止并删除容器
docker stop mysql
docker rm mysql

# 删除所有与 MySQL 相关的匿名卷（警告：这将删除所有 MySQL 容器的数据）
docker volume rm $(docker volume ls -qf dangling=true | grep mysql)

# 删除所有与 MySQL 相关的网络（谨慎操作，确保不删除其他服务需要的网络）
docker network prune
