Docker is a useful container but by default all docker’s stuff will place in /var/lib/docker in many case this will share with root disk space. For easy to maintain disk space we just change docker’s directory to separate disk or path.
Install docker
wget https://get.docker.com -O- | bash -
Edit /etc/docker/daemon.json
{
...
"graph":"/path/to/target"
...
}
Stop dockerd
service docker stop
Move old docker data
rsync -aP /var/lib/docker/* /path/to/target/
Start dockerd
service docker start
