By default the command displays a summary of the In this tutorial, I've taken a generic Linux based approach to show you how to find out disk space occupancy of Docker images, containers and volumes residing on your Linux server at the With containerized applications running in isolated environments, it can be harder than usual to track down problems with applications using too much storage space. I've encountered containers that have a >10GB rootfs by default, so it can also be set on build if you're building those containers. basesize=20G (that would be applied to any newly created container). Copy-on-write is a strategy of sharing and copying files for maximum efficiency. TL;DR - How can I attribute more hard disk space to docker containers?
