How To Remove All Images in Docker

Docker lets you build, ship, and run applications in lightweight containers. However, over time, your system can become clogged with unused images from builds, tests, or outdated versions that consume disk space and make container management harder.

This article shows how to remove all Docker images from your system using the latest Docker CLI commands. It also explains the difference between removing and pruning Docker images, and highlights a few tips to avoid common cleanup mistakes.

The Short Answer

# List all images
$ docker image ls

# Remove dangling images (untagged and unused images)
$ docker image prune -f

# Remove all unused images forcefully and without prompt
$ docker image prune -a -f

Commands to Remove Docker Image

Docker offers several commands for removing system resources, which serve different purposes.

• docker image remove [IMAGE...] or docker image rm [IMAGE...]: Deletes one or more images by ID or tag. Useful for manual cleanup.
• docker image prune: Removes dangling images (images that are both untagged and unused).
