Vagrant Cheat Sheet

Typing vagrant from the command line will display a list of all available commands.

Be sure that you are in the same directory as the Vagrantfile when running these commands!

Creating a VM

  • vagrant init -- Initialize Vagrant with a Vagrantfile and ./.vagrant directory, using no specified base image. Before you can do vagrant up, you'll need to specify a base image in the Vagrantfile.
  • vagrant init <boxpath> -- Initialize Vagrant with a specific box. To find a box, go to the public Vagrant box catalog. When you find one you like, just replace it's name with boxpath. For example, vagrant init ubuntu/trusty64.

Starting a VM

  • vagrant up -- starts vagrant environment (also provisions only on the FIRST vagrant up)
#!/bin/bash
echo 'Starting Provision: web'$1
sudo apt-get update
sudo apt-get install -y nginx
echo "<h1>Machine: web"$1"</h1>" >> /usr/share/nginx/html/index.html
echo 'Provision web'$1 'complete'
#!/bin/bash
echo 'Starting Provision: lb1'
sudo apt-get update
sudo apt-get install -y nginx
sudo service nginx stop
sudo rm -rf /etc/nginx/sites-enabled/default
sudo touch /etc/nginx/sites-enabled/default
echo "upstream testapp {
server 10.0.0.11;

Python merge sort in place, so space complexity is O(1)
import random
def merge_sort(xs):
"""Inplace merge sort of array without recursive. The basic idea
is to avoid the recursive call while using iterative solution.
The algorithm first merge chunk of length of 2, then merge chunks
of length 4, then 8, 16, .... , until 2^k where 2^k is large than
the length of the array
