docker-kill() {
    # usage: docker-kill
    # kill all active docker processes
    local target="$(docker ps -q)"
    [[ -n "$target" ]] && {
        echo "$target" | xargs -i docker kill {}
    }
}
 
docker-clean() {
    # usage: docker-clean
    # kill all docker processes and delete all docker images
    docker-kill
    local dang_target="$(docker images -f "dangling=true" -q)"
    local target="$(docker images --format "{{.Repository}}:{{.Tag}}")"
    echo "dang_target: $dang_target"
    [[ -n "$dang_target" ]] && {
        echo "$dang_target" | xargs docker rmi -f
    }
    echo "target: $target"
    [[ -n "$target" ]] && {
        echo "$target" | xargs docker rmi -f
    }
    docker system prune -f
    docker volume prune -f
