Webhook receiver for Git deployments

Webhook receiver for Git deployments

This project started as a dirty & quick hack to perform some deployment actions triggered by a Git webhook.

I looked a little bit at other projects and didn't found any one that suited my needs, so I started this project... and then it grew a little bit and become something more versatile than the quick hack originally intended.

This project is aimed at DevOps or sysadmin that have git repositories, typically with a VIP-branch, and automatic deployment. You may want to have different branches for stage and production or set up push permissions differently to the different branches. This utility, when a webhook is received, will update the local Git repository and perform the commands in the settings.

Quickstart

• Create and activate a Virtual Environment:

virtualenv --python=/usr/bin/python3 /path/to/venv
source /path/to/venv/bin/activate

• Install the package: pip install webhooks_git_automata
• Create a settings.yaml
• Set up a service (e.g. a systemd service file) that does something along:

/path/to/venv/bin/wh-gitd /path/to/settings.yaml

Implementation details

This project contains a minimal Flask server that answers the POST webhooks sent by a Git server like GitLab, GitHub or Gogs. The server is started through the Flask's app.run method.

Not a lot of traffic is expected, but you may want to set up a reverse proxy in front of the Flask server, or add some fancier method like a WSGI or uWSGI or similar layer.

Typical git servers expect the webhook to send a quick reply (in general, HTTP connections are intended to be short lived) so there is a worker/tasks approach. There is a very simple implementation base on Threading and a shared Queue. More complex implementations may be added in the future (pull requests welcome).
