Python Placeholder App

This repository contains a simple Python Flask application that serves as a placeholder or dummy app for testing purposes. The application simply returns a "Hello, world!" message in JSON format when accessed. It can be containerized using Docker, making it suitable for testing pipeline processes.

You can deploy it to a test environment, then send HTTP requests to it and check the responses to verify that your pipeline is working correctly.
