fabtools 0.5.1

Tools for writing awesome Fabric files

About

fabtools includes useful functions to help you write your Fabric files.

fabtools makes it easier to manage system users, packages, databases, etc.

fabtools includes a number of low-level actions, as well as a higher level interface called fabtools.require.

Using fabtools.require allows you to use a more declarative style, similar to Chef or Puppet.

Installing

Here is an example fabfile.py using fabtools:

from fabric.api import *
from fabtools import require
import fabtools

@task
def setup():

    # Require some Debian/Ubuntu packages
    require.deb.packages([
        'imagemagick',
        'libxml2-dev',
    ])

    # Require a Python package
    with fabtools.python.virtualenv('/home/myuser/env'):
        require.python.package('pyramid')

    # Require an email server
    require.postfix.server('example.com')

    # Require a PostgreSQL server
    require.postgres.server()
    require.postgres.user('myuser', 's3cr3tp4ssw0rd')
    require.postgres.database('myappsdb', 'myuser')

    # Require a supervisor process for our app
    require.supervisor.process('myapp',
        command='/home/myuser/env/bin/gunicorn_paster /home/myuser/env/myapp/production.ini',
        directory='/home/myuser/env/myapp',
        user='myuser'
        )

    # Require an nginx server proxying to our app
    require.nginx.proxied_site('example.com',
        docroot='/home/myuser/env/myapp/myapp/public',
        proxy_url='http://127.0.0.1:8888'
        )
