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
git init
curl -sL https://raw.githubusercontent.com/flyingcircusio/batou/main/bootstrap | sh
git commit -m "Start a batou project."
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/environment.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

Hacking
- Make sure
mercurial
and subversion
are installed and in $PATH
. - Run
./develop.sh
to create a local virtualenv with everything set up. - Run the test suite using:
bin/tox
- Build the documentation using:
cd doc; make
- Set up GPG for the examples with
export GNUPGHOME=<DIRECTORY OF BATOU HERE>/src/batou/secrets/tests/fixture/gnupg
- Make sure age is installed and in
$PATH
for age encryption support.
Development and release process
- Changes should be accompanied with a changelog entry. Use
./changelog.sh
to create one. - Releasing will create a tag and publishes the package to pypi. Use
./release-this.sh
to create a release.
