Docker Cleanup Cheat Sheet

System Prune

Remove all unused data (containers, networks, images).

docker system prune

Remove everything including volumes:

docker system prune -a --volumes

docker system prune -f

Check Disk Usage

Show Docker disk usage.

docker system df

Verbose output:

docker system df -v

Remove Stopped Containers

Delete all stopped containers.

docker container prune

Remove specific container:

docker rm <container-id>

Remove all containers (stopped and running):

docker rm -f $(docker ps -aq)

Remove Images

Remove unused images.

docker image prune

Remove all unused images (not just dangling):

docker image prune -a

Remove specific image:

docker rmi <image-id>

Remove all images:

docker rmi $(docker images -q)

Remove Dangling Images

Remove untagged images.

docker image prune

List dangling images first:

docker images -f dangling=true

Remove Volumes

Delete unused volumes.

docker volume prune

Remove specific volume:

docker volume rm <volume-name>

Remove all volumes:

docker volume rm $(docker volume ls -q)

Remove Networks

Delete unused networks.

docker network prune

docker network rm <network-name>

Remove Build Cache

Clear Docker build cache.

docker builder prune

docker builder prune -a

Stop All Containers

Stop all running containers before cleanup.

docker stop $(docker ps -q)

Remove by Filter

Remove containers created before specific time.

docker container prune --filter "until=24h"

Remove images by label:

docker image prune --filter="label=deprecated=true"
