Docker Housekeeping

Some simple housekeeping commands for Docker.


Problem: no space left on device when trying to build an image, but there is apparently lots of disk space left?

Cleanup Commands

docker system prune

This will remove:

  • all stopped containers
  • all networks not used by at least one container
  • all dangling images
  • all dangling build cache

docker image prune

This will remove:

  • all dangling images

docker volume prune

This will remove:

  • all local volumes not used by at least one container

docker buildx prune

Removes build cache.

Using Until Filter

These commands accept an until.

Relative times are allowed e.g.

docker image prune --filter "until=48h"

in addition to absolute date e.g.

docker image prune --filter "until=2021-07-01"

This page is a web-friendly rendering of my project notes shared in the LittleCodingKata GitHub repository.

LittleCodingKata is my collection of programming exercises, research and code toys broadly spanning things that relate to programming and software development (languages, frameworks and tools).

These range from the trivial to the complex and serious. Many are inspired by existing work and I'll note credits and references where applicable. The focus is quite scattered, as I variously work on things new and important in the moment, or go back to revisit things from the past.

This is primarily a personal collection for my own edification and learning, but anyone who stumbles by is welcome to borrow, steal or reference the work here. And if you spot errors or issues I'd really appreciate some feedback - create an issue, send me an email or even send a pull-request.
