a script for doing an annoying job - removing unused docker containers

docker_cleanup.sh

# ! /bin/bash

if [ $# -eq 0 ]
then
    echo "the docker target is not provided, aborting..."
    exit 1
fi

target=$1

echo "starting looking up for docker containers of target $target"

containers_found=$(docker ps -a | grep $target | grep Exited | awk '{print $1}')

for container_id in $containers_found
do
    docker rm $container_id
done

echo "no docker containers need to remove, stopping..."

Apparently, I recently realized that the docker run cmd could be used with --rm flag which removes the container once it gets stopped.
So this script is useless :))
