A server-oriented auto-deployment utility for any type of program or script

Project description

# Huddle

`Huddle` is an application that allows one or more programs to be started, monitored, stopped, updated, and
restarted from one or more configuration files. This program works in Windows and Linux.

More complete documentation may be found on [GitHub Pages](

## Configuration File Format

The purpose of this program is to auto-deploy any arbitrary program in a fashion that is more suited to auto-scaling
servers. Instead of having a git hook that pushes to a known set of servers, a running server continually polls
the git at specified intervals and - when there is an update - the server will pull the new data and re-deploy.

All of this is done using a configuration file, so no Python knowledge is required.

The simplest example of a configuration file will simply check for updates for a set of files every 60s:

"repository": {
"remote path": "",
"local path": "/home/ubuntu/git_example",

A more comprehensive configuration file:

"repository": {
"remote": "origin",
"remote path": "",
"local path": "/home/ubuntu/git_example",
"branch": "develop",
"executable": "/usr/bin/git"

"timing": {
"minimum": 60,
"maximum": 600

"application": {
"start": "/home/ubuntu/py3env/bin/python -m"

This file will initially start the application using the command under `start`, and check for application updates
every 60s to 600s (random). When an update to the `develop` branch is detected, the application will be halted, the
local file updated, and the application re-started automatically.

Note that INI is also supported. The above equivalent configuration:

remote = origin
remote path:
local path: C:/_code/_git_example
branch: develop
executable: /usr/bin/git

minimum = 60
maximum = 600

start = /home/ubuntu/py3env/bin/python -m

The current flow chart for each application is:

This program, at initialization, should be all that is required to clone a remote repository, verify test status,
sync changes, and stop/start/reboot the application.

## Configuration Files

All configuration files should be saved within a particular directory with `.json` extensions. Any file that is
prefixed with an underscore `_` will be ignored.


Or, in windows:


Note that `_app3.json` will be ignored.

## Running the Application

To execute huddle, simply pass it the path to your configuration files using the `-c` or `--config` options:

python -m huddle -c /home/ubuntu/config_files
python -m huddle -c C:\config_files

Depending on the install location for huddle (virtual environments, etc.), the `python -m` may not be required:

huddle -c /home/ubuntu/config_files
huddle -c C:\config_files

# Status

The interface is stable enough to depend on. Testing is at about 60% on unit tests and I have verified basic
functionality on windows and on linux (Debian). Currently, the 'check tests' portion of the API is not implemented
and - if attempted - will raise a `NotImplementedError`.

# Installation

Install with `pip install huddle` or simply download the most recent version of this repository and
`python install`.
