Update docker containers’ default storage location on Ubuntu

The storage location of Docker images and containers [1]

A Docker container consists of network settings, volumes, and images. The location of Docker files depends on your operating system:

• Ubuntu: /var/lib/docker/

Change storage location [2]

Another often posted solution is to stop Docker:

sudo systemctl stop docker

Edit the /etc/default/docker file by adding the new location with the -g in the DOCKER_OPTS line:

DOCKER_OPTS="-dns 8.8.8.8 -dns 8.8.4.4 -g /mnt/newlocation"

Then start Docker again:

sudo systemctl start docker=
