Single shell script to remove all containers, images and volumes used by containers. The script first tries to stop containers if there is any running, then remove the containers, followed by images removal and finally the container volumes.

clear-images.sh

#!/bin/bash
###########################################
#
# Simple Shell script to clean/remove all container/images
#
# The script will 
#  - first stop all running containers (if any),
#  - remove containers
#  - remove images
#  - remove volumes
#

# stop all running containers
echo '####################################################'
echo 'Stopping running containers (if available)...'
echo '####################################################'
docker stop $(docker ps -aq)

# remove all stopped containers
echo '####################################################'
echo 'Removing containers ..'
echo '####################################################'
docker rm $(docker ps -aq)


# remove all images
echo '####################################################'
echo 'Removing images ...'
echo '####################################################'
docker rmi $(docker images -q)

# remove all stray volumes if any
echo '####################################################'
echo 'Revoming docker container volumes (if any)'
echo '####################################################'
docker volume rm $(docker volume ls -q)

sweet. added -f after rmi.

TY for this!

Glad to be helpful

And adding to the end as an option: docker system prune -f
... would clear the docker internal networks too; maybe not needed by all users

Thank you for the script!

I have docker volume rm $(docker volume ls -f dangling=true -q) in a script. If I run it just in the shell and not in the script, it works as expected. when I run the script it gives me:

Any idea why it does not work in the script?

@fromage9747 docker volume ls -f dangling=true -q is returning nothing.

#!/bin/bash
