Introduction

Python-vagrant is a python module that provides a thin wrapper around the vagrant command line executable, allowing programmatic control of Vagrant virtual machines (boxes). This module is useful for:

• Starting a Vagrant virtual machine (VM) (up).
• Terminating a Vagrant VM (destroy).
• Halting a Vagrant VM without destroying it (halt).
• Querying the status of a VM or VMs (status).
• Getting ssh configuration information useful for SSHing into the VM. (host, port, ...)
• Running vagrant commands in a multi-VM environment (http://vagrantup.com/v1/docs/multivm.html) by using vm_name parameter.
• Initializing the VM based on a named base box, using init().
• Adding, Removing, and Listing boxes (box add, box remove, box list).
• Provisioning VMs - up() accepts options like no_provision, provision, and provision_with, and there is a provision() method.
• Using sandbox mode from the Sahara gem (https://github.com/jedi4ever/sahara).

This project begain because I wanted python bindings for Vagrant so I could programmatically access my vagrant box using Fabric. Drop me a line to let me know how you use python-vagrant. I'd love to share more use cases. -Todd DeLuca

Versioning and API Stability

This package is beta and its API is not guaranteed to be stable. The API attempts to be congruent with the vagrant API terminology, to facilitate knowledge transfer for users already familiar with Vagrant. Over time, the python-vagrant API has changed to better match the underling vagrant CLI and to evolve with the changes in that CLI.

The package version numbering is in the form 0.X.Y. The initial 0 reflects the beta nature of this project. The number X is incremented when backwards-incompatible changes occur. The number Y is incremented when backwards-compatible features or bug fixes are added.

Contribute

If you use python and vagrant and this project does not do what you want, please open an issue or a pull request on github at https://github.com/todddeluca/python-vagrant.

Please see CHANGELOG.md for a detailed list of contributions and authors.

When making a pull request, please include unit tests that test your changes and make sure any existing tests still work. One can test with:

cd /path/to/python-vagrant
nosetests

Requirements

• Vagrant 1.1 or greater (urrently tested with 1.5). Using the latest version of Vagrant is strongly recommended.
• Vagrant requires VirtualBox (e.g. VirtualBox 4.2.10) or another provider.
• Python 2.7 (the only version this package has been tested with.)
• The Sahara gem for Vagrant is optional. It will allow you to use SandboxVagrant.

Installation

Usage

A contrived example of starting a vagrant box (using a Vagrantfile from the current directory) and running a fabric task on it:

import vagrant
from fabric.api import env, execute, task, run

@task
def mytask():
    run('echo $USER')


v = vagrant.Vagrant()
v.up()
env.hosts = [v.user_hostname_port()]
env.key_filename = v.keyfile()
env.disable_known_hosts = True # useful for when the vagrant box ip changes.
execute(mytask) # run a fabric task on the vagrant host.

Another example showing how to use vagrant multi-vm feature with fabric:

import vagrant
from fabric.api import *

@task
def start(machine_name):
   """Starts the specified machine using vagrant"""
   v = vagrant.Vagrant()
   v.up(vm_name=machine_name)
   with settings(host_string= v.user_hostname_port(vm_name=machine_name),
                 key_filename = v.keyfile(vm_name=machine_name),
                 disable_known_hosts = True):
        run("echo hello")
