Store docker images in /home/ filesystem (linux)

1. Stop docker service

sudo systemctl stop docker.service docker.socket

2. Create a directory in home filesystem for docker images

mkdir /home/docker

3. If you want to preserve current images rsync them over to the new directory

rsync -avxP /var/lib/docker/ /home/docker

4. Add "data-root": "/home/docker" to /etc/docker/daemon.json

{
+ "data-root": "/home/docker"
}

5. Reload and start docker service

sudo systemctl daemon-reload
sudo systemctl start docker.socket docker.service

6. Verify the changes

Run docker images and grab an IMAGE ID

docker inspect <image_id> --format='{{.GraphDriver.Data.WorkDir}}'

Check the output of the above to ensure it's in /home/docker
