How to get the list of dependent child images in Docker?

Question

I\'m trying to remove an image and I get:

# docker rmi f50f9524513f  
Failed to remove image (f50f9524513f): Error response from daemon: conflict: unable to

Based on slushy and Michael Hoffman answers, if you don't have a ton of images you can use this shell function:

docker_image_desc() {
  for image in $(docker images --quiet --filter "since=${1}"); do
    if [ $(docker history --quiet ${image} | grep ${1}) ]; then
      docker_image_desc "${image}"
    fi
  done
  echo "${1}"
}

and then call it using

docker_image_desc  | awk '!x[$0]++'
