airflow-deploy-softwrd 0.0.9

A Flask application to handle postman webhooks for deploying and taking down repositories.

Airflow Deploy Softwrd

This is a Flask application that handles GitHub webhook POST requests for deploying and taking down repositories using Docker Compose. It is designed for managing Airflow deployments of softwrd in-house hosted repositories.

Features

• Deploy specified branches of a repository on push events (via /payload).
• Bring down specified branches of a repository (via /putdown).
• Retrieve secrets from AWS Secrets Manager for environment and Airflow variables.
• Automatically configure environment variables from secrets.
• Supports both HTTPS and SSH cloning (configurable).
• Runs deployment and takedown logic in background threads for responsiveness.

Prerequisites

• Python 3.9 or higher
• Docker and Docker Compose
• AWS credentials setup if using Secrets Manager

Installation

You can install the package from PyPI:

pip install airflow_deploy_softwrd

Configuration

AWS Credentials Setup

Set up your AWS credentials using the following command:

$Env:AWS_ACCESS_KEY_ID = "your-access-key-id"
$Env:AWS_SECRET_ACCESS_KEY = "your-secret-access-key"

you must have to set up your AWS credentials in your environment variables before running the application.

Usage

To run the server, use the following command:

airflow_deploy_softwrd /path/to/your/working/directory /path/to/config.json

Command Line Arguments

• /path/to/your/working/directory: The base directory where repositories will be cloned and operated.
• /path/to/config.json: Path to the configuration file containing allowed branches.

Configuration File

Create a JSON configuration file, e.g., config.json, with the following contents to specify allowed branches and SSH support: Set "SSH": true if you want to clone repositories using SSH instead of HTTPS.

{
  "allowed_branches": ["develop", "main", "Airflow-Changelog"],
  "SSH": false
}

Required AWS Secrets

Set up the following secrets in AWS Secrets Manager:

• airflow_deployment_env: Secret containing environment variables for deploying Airflow (as a JSON object).
• airflow_variables_env: Secret containing Airflow variable configurations (as a JSON object).

POSTMAN Webhooks

Set up your webhook sender (e.g., GitHub or POSTMAN) to point to the following endpoints of your running Flask application:

• Deploy a branch:

  • http://localhost:6969/payload

• Bring down a branch:

  • http://localhost:6969/putdown

Example Webhook Payloads

Deploy a Branch

The webhook payloads for both endpoints should include the following fields:

Branch Name Format:

• You can provide the branch name as either just the branch name (e.g., main) or prefixed with refs/heads/ (e.g., refs/heads/main).
• Other formats such as refs/<branch_name> or heads/<branch_name> are not supported and will break the application.

{
  "ref": "refs/heads/main",
  "repository": {
    "clone_url": "https://github.com/yourusername/yourrepo.git",
    "name": "yourrepo"
  },
  "head_commit": {
    "message": "Your commit message"
  }
}

Bring Down a Branch

The webhook for bringing down a branch should contain similar information:

{
  "ref": "refs/heads/main",
  "repository": {
    "clone_url": "https://github.com/yourusername/yourrepo.git",
    "name": "yourrepo"
  },
  "head_commit": {
    "message": "Your commit message"
  }
}

Additional Notes

• The application must be started with two arguments: the base path for repositories and the path to the config file.
• Only branches listed in allowed_branches in your config file will be processed.
• If SSH is set to true in the config, repositories will be cloned using SSH URLs.
• All deployment and takedown operations are run in background threads for non-blocking webhook responses.
