Tunic

A Python library for deploying code on remote servers.

Tunic is designed so that you can make use of as much or as little of its functionality as you’d like, the choice is yours.

It only requires the Fabric library as a dependency and can be installed from the Python Package Index (PyPI) using the pip tool like so.

$ pip install tunic

You could then make use of it in your deploy process like so.

from fabric.api import task
from tunic.api import get_release_id, ReleaseManager, VirtualEnvInstallation

APP_BASE = '/srv/www/myapp'

@task
def deploy():
    stop_my_app()
    release = get_release_id()

    installer = VirtualEnvInstaller(APP_BASE, ['myapp'])
    release_manager = ReleaseManager(APP_BASE)

    installer.install(release)
    release_manager.set_current_release(release)

    start_my_app()

The above snippet is just the start, take a look around the code base for more methods that can save you work in your deploy process.
