Deploying a Web Application over Kubernetes

Deploying applications consistently across environments requires containerization and orchestration to manage scalability, availability, and fault tolerance. Docker packages applications into isolated containers, while Kubernetes automates deployment, scaling, and lifecycle management.

In this project, we'll deploy a containerized web application using Docker and Kubernetes, demonstrating the complete workflow from containerization to production exposure. We'll use Docker to create container images, push them to Docker Hub for centralized storage, then deploy the application on a Kubernetes cluster using Pods and Deployments. The system will handle automatic restarts, load balancing across replicas, and external traffic routing through Kubernetes services.

We'll containerize the application with Dockerfile configurations, create and test Kubernetes Pods for single-instance deployments, then scale up using Deployment objects for replica management. Finally, we'll expose the application externally with a Kubernetes Service and verify accessibility. By the end, we'll have hands-on experience with Docker containerization, Kubernetes deployment, Pod management, service networking, and container orchestration applicable to any cloud-native application or microservices deployment.
