mkdir -p /etc/systemd/system/docker.service.d
vi /etc/systemd/system/docker.service.d/docker.conf

 Add following into above file, but prior to that please check the storage driver used by your server by running :docker info |grep "Storage Driver" and put the output i.e.. "overlay or devicemapper" in below content

Code Block
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd --graphdata-root=<dir_having_enough_space> --storage-driver=<output of docker info |grep "Storage Driver">

sudo systemctl stop docker
sudo systemctl daemon-reload
