Remove dangling Docker images. Useful when you often use `docker compose pull` and your disk gets clogged with old images.

docker-rm-dangling-imgs.sh

#!/bin/bash

set -euo pipefail

echo "These images are gonna be removed:"

docker images -f "dangling=true"

echo
read -p "Do you want to continue? [yN]" -n 1 -r
echo

if [[ $REPLY =~ ^[Yy]$ ]]
then
  echo "Removing dangling images..."
  docker rmi $(docker images -f "dangling=true" -q)
  echo "All done"
