从零搭建基于树莓派5和X1009扩展板的OMV 8 nas系统——docker 环境配置
1、新建appdata,data,backup_compose,docker共享文件夹
2、点击服务→Compose→设置，依次填写相关文件路径，其中Docker 存储地址从共享文件夹页面复制而来，保存应用
3、迁移原docker 配置文件/var/lib/docker/ 到hhd下的新建docker配置文件路径/srv/dev-disk-by-uuid-7acbde88-ba3d-4696-b6ba-d86356bddb33/docker/
root@R-PI5:/# rsync -avz /var/lib/docker/* /srv/dev-disk-by-uuid-7acbde88-ba3d-4696-b6ba-d86356bddb33/docker/

删除原文件
root@R-PI5:/# rm -rf /var/lib/docker/*
4、创建docker 用户appuser,shell选择nologin,保存并应用
在右上角图标中选择UID,GID
5、给appdate 文件夹的访问控制列表添加 appdata 用户的读写权限，保存并应用
6、至此完成docker 环境配置，接下来就可以部署容器了
