problem:
[root@localhost ~]# 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.
[root@localhost ~]# docker daemon
WARN[0000] Usage of loopback devices is strongly discouraged for production use. Please use `--storage-opt dm.thinpooldev` or use `man docker` to refer to dm.thinpooldev section.
FATA[0000] Error starting daemon: error initializing graphdriver: "/var/lib/docker" contains other graphdrivers: overlay; Please cleanup or explicitly choose storage driver (-s <DRIVER>)

resolve:
# rm /var/lib/docker/overlay/ -rf

--------------------------------
Docker not starting “ could not delete the default bridge network: network bridge has active endpoints”"

Run
sudo mv /var/lib/docker/network/files/ /tmp/dn-bak

to reset your networks. Then restart docker (sudo systemctl restart docker or sudo service docker restart depending on your OS). If everything works again you can delete the dn-bak directory.

--------------------------------

[root@localhost ~]# gedit /etc/sysconfig/docker
DOCKER_OPTS="--dns 8.8.8.8 --dns 75.75.75.76"
DOCKER_OPTS="--iptables=true --dns=10.20.100.1 --dns=8.8.8.8"

--------------------------------

On arch linux I needed
ip link set down docker0 instead of ifconfig docker0 down and
systemctl restart docker instead of service docker start.
To delete all images, I did
docker rmi $(docker images -q)

++++++++++++++++
docker tag c8a648134623 docker.io/centos:core

/etc/sysconfig/docker-storage这个配置文件
