迁移docker数据
[root@localhost ~]# systemctl stop docker
Warning: Stopping docker.service, but it can still be activated by:
docker.socket
[root@localhost ~]# systemctl stop docker.socket
[root@localhost ~]#
[root@localhost ~]# mkdir /data/docker
同步docker镜像数据
nohup rsync -avz /var/lib/docker/ /data/docker/ &
cp -r /var/lib/docker/ /data/docker/
编辑/etc/docker/daemon.json，添加参数，将docker的目录迁移绑定
"data-root ": "/data/docker"
[root@localhost ~]# systemctl restart docker
