Overview

The Flask Sample Application is a well-crafted representation of how to leverage the Flask web framework to create a Python-based web application. Designed for deployment on the OpenShift platform, this application showcases the seamless integration of Flask with gunicorn, ensuring robust performance for web services. It serves as a great starting point for developers looking to understand the deployment process of Python applications in a cloud environment.

By following this sample, users can gain insights into using the Source-to-Image (S2I) builder to manage app configurations, making it an excellent resource for both beginners and seasoned developers. The setup is straightforward, facilitating a smooth transition from local development to deploying applications in the cloud.

Features

WSGI Application Structure: Requires the WSGI application code to be organized with wsgi.py as the main file and application as the entry point, ensuring adherence to conventional web integration standards.
Gunicorn Integration: The application leverages the gunicorn WSGI server, which is specified in the requirements.txt file, providing a reliable and efficient server for hosting web applications.
Environment Variable Management: A .s2i/environment file allows flexibility in adjusting environment variables, offering customizable configurations for different deployment scenarios.
Version Compatibility: Supports multiple Python versions (2.7, 3.3, 3.4, and latest), allowing developers to choose their preferred environment while staying updated with the latest features.
Automatic Language Detection: When deploying via the oc command line tool, OpenShift can automatically identify the application type through a requirements.txt file, simplifying the setup process.
Smooth Deployment Steps: Clear instructions for both web console and command line deployments make it easy for users to get their application up and running on OpenShift.
