batou 1.12.2

A utility for automating multi-host, multi-environment software builds and deployments.

batou helps you to automate your application deployments:

• You create a model of your deployment using a simple but powerful Python API.
• You configure how the model applies to hosts in different environments.
• You verify and run the deployment with the batou utility.

Getting started with a new project is easy:

$ mkdir myproject
$ cd myproject
$ curl https://bitbucket.org/flyingcircus/batou/raw/tip/src/batou/bootstrap-template -o batou
$ chmod +x batou
$ ./batou

Here's a minimal application model:

$ mkdir -p components/myapp
$ cat > components/myapp/component.py
from batou.component import Component
from batou.lib.python import VirtualEnv, Package
from batou.lib.supervisor import Program

    class MyApp(Component):

        def configure(self):
            venv = VirtualEnv('2.7')
            self += venv
            venv += Package('myapp')
            self += Program('myapp',
                command='bin/myapp')

And here's a minimal environment:

$ mkdir environments
$ cat > environments/dev.cfg
[environment]
connect_method = local

[hosts]
localhost = myapp

To deploy this, you run:

$ ./batou deploy dev

Features

• Separate your application model from environments
• Supports idempotent operation for incremental deployments
• Deploy to multiple hosts simultaneously
• Automated dependency resolution for multi-host scenarios
• No runtime requirements on your application
• Encrypted secrets with multiple access levels: store your SSL certificates, SSH keys, service secrets and more to get true 1-button deployments.
• Deploy to local machines, Vagrant, or any SSH host
• Broad SSH feature support by using OpenSSH through execnet
• Only few dependencies required on the remote host
• Ships with a library of components for regularly needed tasks
• self-bootstrapping and self-updating - no additional scripting needed
