问题描述：

闲来无事就在开发电脑上执行了下sudo apt-get upgrade 升级下软件, 升级后docker启动失败.

使用 journalctl -xeu docker.service 查看docker执行日志：

解决方法：

从运行日志里找到关键错误信息：

Mar 04 16:48:10 pop-os dockerd[39273]: time="2023-03-04T16:48:10.399328995+08:00" level=error msg="[graphdriver] prior storage driver devicemapper is deprecated and will be removed in a future release; update the the daemon configuration and explicitly choose this storage driver to continue using it; visit https://docs.docker.com/go/storage-driver/

大致意思就是先前使用的storage driver类型devicemapper现在不推荐使用了，以后有可能以后就废弃掉了。现在都有哪些storage driver呢？可以点开后面给的链接自己看。如果要继续使用devicemapper需要显示指定。我现在就想让docker现在能运行起来先，找到对应配置项storage-driver添加到/etc/docker/dameon.json文件中.
