sudo apt-get update
sudo apt-get install ca-certificates curl

sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
# If you use an Ubuntu derivative distro, such as Linux Mint, you may need to use UBUNTU_CODENAME instead of VERSION_CODENAME.

sudo service docker stop

# Copy the files to the new location
sudo rsync -axPS /var/lib/docker/ /new/path/to/docker-data
# -a, --archive             archive mode; equals -rlptgoD (no -H,-A,-X)
# -x, --one-file-system     don't cross filesystem boundaries
# -P                        show progress during transfer
# -S, --sparse              handle sparse files efficiently

sudo service docker start

# Check Docker has started up using the new location
docker info | grep 'Docker Root Dir'

# remove docker old storage directory
sudo rm -rf /var/lib/docker
