docker啟動異常driver not supported

使用阿里雲機器重啟docker服務出現錯誤提示信息

[root@iz2ze5ivwiz2bnwddc20k4z ~]# systemctl restart docker
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

 使用 journalctl -xe 查看詳情

[root@iz2ze5ivwiz2bnwddc20k4z ~]# journalctl -xe

解決方案：修改docker鏡像，容器存放位置。

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
