Modify Docker default storage path

The default file storage path of docker is placed under /var/lib/docker. You can view the return value of docker root through docker info

 

#systemctl stop docker
#cp -rf /var/lib/docker /data/
#mv/var/lib/docker/var/lib/docker.bak
#ln -sf /data/docker /var/lib/docker

 

[root@dock ~]#docker info | grep -i root
Docker Root Dir: /data/docker
