默認情況下docker的存放位置為:
/var/lib/docker
[root@iz2ze5ivwiz2bnwddc20k4z ~]# sudo mv /var/lib/docker /var/lib/docker.old 正常啟動docker
[root@iz2ze5ivwiz2bnwddc20k4z ~]# service docker start
Redirecting to /bin/systemctl start docker.service檢查是否能查看鏡像
[root@iz2ze5ivwiz2bnwddc20k4z ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE確認無誤后卸載臨時掛載點，刪除/var/lib/docker.old
[root@iz2ze5ivwiz2bnwddc20k4z ~]# rm -rf /var/lib/docker.old
