【问题描述】：
我是 Docker 新手，不太了解 Linux。我正在尝试使用 Docker 构建自己的本地开发环境。我正在使用 docker-compose 实用程序。我想将 MySQL 数据存储在本地卷中。当我第一次运行docker-compose build 和docker-compose up -d 命令时，没有错误。 MySQL 容器中的数据进入本地文件夹。一切都很好，除了一个：当我想更改我的 docker-compose.yml 文件并重建容器时，我得到一个错误
vo@vo-ThinkPad-Edge-E330:~/www/test$ docker-compose build
mysql uses an image, skipping
nginx uses an image, skipping

我发现该文件夹的所有者是来自root 组的systemd-coredump。所以我有两种方法：
sudo docker-compose build- 删除具有
sudo权限的/home/vo/www/test/docker/mysql/dbdata 文件夹并再次运行docker-compose build。
所以，我的问题是：这应该是这样还是有可能解决权限问题？
