Docker startup exception driver not supported

An error message appears when restarting the docker service using an Alibaba Cloud machine

[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.

 Use journalctl -xe for details

[root@iz2ze5ivwiz2bnwddc20k4z ~]# journalctl -xe

Solution: Modify the docker image and the container storage location.

By default, the storage location of docker is:

/var/lib/docker

[root@iz2ze5ivwiz2bnwddc20k4z ~]# sudo mv /var/lib/docker /var/lib/docker.old  

Start docker normally

[root@iz2ze5ivwiz2bnwddc20k4z ~]# service docker start
Redirecting to /bin/systemctl start docker.service

Check if the mirror can be viewed

[root@iz2ze5ivwiz2bnwddc20k4z ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

After confirmation, unmount the temporary mount point and delete /var/lib/docker.old

[root@iz2ze5ivwiz2bnwddc20k4z ~]# rm -rf /var/lib/docker.old
