If you using Docker Toolbox then your installation include local instance of Docker Machine. Usually the instance use driver and instance of Oracle VirtualBox application.

Tune disk size

By default driver for VirtualBox create a virtual machine with 20GB of disk space. When developing a new image (Dockerfile or Docker Compose), this volume quickly ends and it makes sense to immediately allocate several times more space on your hard drive.

To change various parameters of VirtualBox for Docker check options: https://docs.docker.com/machine/drivers/virtualbox/#options

Let's create a new docker machine with increased amount of disk space.

Put content to /etc/systemd/system/limit-docker-memory.slice file. Then add a line "cgroup-parent": "limit-docker-memory.slice" to /etc/docker/daemon.json. Then restart the docker: systemctl daemon-reload; systemctl restart docker
