Clean up a vagrant box before packaging

package-vagrant-box.sh

#!/bin/bash

# We’re now going to clean up disk space on the VM so when we package it into a new Vagrant box, it’s as clean as possible. First, remove APT cache
sudo apt-get clean

# Then, “zero out” the drive (this is for Ubuntu):
sudo dd if=/dev/zero of=/EMPTY bs=1M
sudo rm -f /EMPTY

# Lastly, let’s clear the Bash History and exit the VM:
cat /dev/null > ~/.bash_history && history -c && exit

# We’re now going to repackage the server we just created into a new Vagrant Base Box. It’s very easy with Vagrant:
vagrant package --output mynew.box
