A simple command line tool to nuke your docker

docker-nuke.rb

#!/usr/bin/env ruby
require 'docker'

actions = {
    "rmi" => lambda{|force|
        Docker::Image.all.map{|img| 
            puts img.id[0..12]
            img.remove(:force => force)}
    },
    "rm" => lambda{|force|
        Docker::Container.all(:all => true).map{|cont|
            puts cont.id[0..12]
            cont.delete(:force => force)}
    }
}

if ARGV[0].nil? or !ARGV[1].nil? and ARGV[1] != '-f'
    puts "Usage: #{__FILE__} <rm -f> <rmi -f> \n"\
        "\trm - Remove all containers\n"\
        "\trmi - Remove all images\n"\
        "\t-f - Force deletion\n"
    exit
end

force = (ARGV[1] == '-f') ? true : false
actions[ARGV[0]].call(force)

Be sure to chmod +x and put it in your ~/bin for the best nuking experience
