Installing Python

Most Unix/Linux systems come with python pre-installed:

$ python -V

habbdt

#!/usr/bin/env python

import sys, paramiko

if len(sys.argv) < 5:
    print "args missing"
    sys.exit(1)

hostname = sys.argv[1]
password = sys.argv[2]

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!

Common Vagrant Commands

• vagrant up -- starts vagrant environment (also provisions only on the FIRST vagrant up)
• vagrant status -- outputs status of the vagrant machine
• vagrant halt -- stops the vagrant machine
• vagrant reload -- restarts vagrant machine, loads new Vagrantfile configuration
• vagrant provision -- forces reprovisioning of the vagrant machine
