feat: Add Hello World app with visitor counter for Kubernetes #131872
Conversation
This project creates a simple Python Flask web application that:
- Displays "Hello World!"
- Counts page visitors.
The visitor counter initially used an in-memory store and was later
updated to use Redis for persistence.
The project includes:
- `app.py`: The Flask application.
- `Dockerfile`: For containerizing the application.
- Kubernetes manifests:
- `deployment.yaml`: For the web app deployment.
- `service.yaml`: To expose the web app.
- `redis-deployment.yaml`: For Redis deployment.
- `redis-service.yaml`: For the Redis internal service.
This setup allows the application to be deployed to a Kubernetes
cluster, demonstrating containerization, deployment, service exposure,
and inter-service communication (app to Redis).
