Python bindings for interacting with Vagrant virtual machines.

Primary LanguagePythonMIT LicenseMIT

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 box (up).
  • Terminating a Vagrant box (destroy).
  • Halting a Vagrant box without destroying it (halt).
  • Querying the status of a box (status).
  • Getting ssh configuration information useful for SSHing into the box. (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 - up() accepts no_provision and there is a provision() method.
  • Using sandbox mode from the Sahara gem (https://github.com/jedi4ever/sahara).

This package is alpha 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.

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. -Todd DeLuca

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 (Currently tested with 1.1.5).
  • 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

Install from pypi.python.org

Download and install python-vagrant:

pip install python-vagrant

Install from github.com

Clone and install python-vagrant

cd ~
git clone git@github.com:todddeluca/python-vagrant.git
cd python-vagrant
python setup.py install

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")
