Provides the prune command to remove unused images, containers, volumes, and networks.
Prune images
docker image prune removes images that have no tags and are not referenced by containers. This image is called a dangling image.
Example 1: docker image prune
Redis removed, no tags and no references
#docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES # docker images REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest ae2feff98a0c 4 days ago 133MB redis <none> ef47f3b6dc11 8 days ago 104MB centos latest 300e315adb2f 12 days ago 209MB ubuntu latest f643c72bc252 3 weeks ago 72.9MB docs/ latest 32ed84d97e30 6 months ago 1GB # docker image prune # docker images REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest ae2feff98a0c 4 days ago 133MB centos latest 300e315adb2f 12 days ago 209MB ubuntu latest f643c72bc252 3 weeks ago 72.9MB docs/ latest 32ed84d97e30 6 months ago 1GB
Example 2: Remove all images that are not used by containers -a
docker image prune -a
Skip warning prompt: --force or -f
docker image prune -f
Example 3: Perform filtering and deletion:
Image created over 24 hours
docker image prune -a --filter "until=24h"
About the filter, viewdocker image prune manual
Remove containers
When the container is stopped, it will not be deleted automatically unless --rm is specified when docker run. A stop-writable container will still take up disk space, so clear it and use the docker container prune command.

Remove volume
The volume is used by one or more containers and takes up host space. Volumes are not automatically removed because they will corrupt data.
docker volume prune

Remove the network
Docker networks do not take up disk space, but they create iptables rules, bridge network services, and route entries. Clear networks that are not used by containers, do this
docker network prune

Remove Everything
The docker system prune command is a shortcut for removing images, containers, and networks.
In Docker 17.06.0 and earlier, volumes can also be removed. In Docker 17.06.1 or later, the parameter --volumes needs to be specified.
Example (the volume was not removed):
# docker system prune WARNING! This will remove: - all stopped containers - all networks not used by at least one container - all dangling images - all build cache Are you sure you want to continue? [y/N] y
Example (with the function of removing volume): Add --volumes
# docker system prune --volumes WARNING! This will remove: - all stopped containers - all networks not used by at least one container - all volumes not used by at least one container - all dangling images - all build cache Are you sure you want to continue? [y/N] y
