How to relocate Docker Data Directory
Relocated the Docker Data Directory on my workstation (laptop).
One was the size of the partition.
The second was the security.
It went to be on a resized and encrypted partition.
$ du -sh /var/lib/docker
5.1G /var/lib/docker
$ sudo systemctl stop docker
$ sudo vim /etc/docker/daemon.json
{
"graph": "/path/to/your/docker"
}
$ sudo rsync -aP /var/lib/docker/ /path/to/your/docker
$ sudo mv /var/lib/docker /var/lib/docker.old
