Stop the Docker daemon.

sudo service docker stop

Create a file called daemon.json under the /etc/docker directory with the following content:

{
        "data-root": "<path to your Docker folder>"
  }

Copy the current data directory to the new one.

sudo rsync -aP /var/lib/docker/ <path to your Docker folder>

Rename the old docker directory.

sudo mv /var/lib/docker /var/lib/docker.bkp

After confirming that the change was successful, you can remove the backup file.

sudo rm -rf /var/lib/docker.bkp

Start the Docker daemon.

sudo service docker start
