Secure Deployment of Containerized App to Kubernetes using Harbor & TLS

Description

This project showcases a secure end-to-end container deployment to Kubernetes using a self-hosted Harbor registry over HTTPS. It includes TLS certificate generation, Docker and Minikube trust setup, and Kubernetes secret-based authentication. The goal was to demonstrate practical DevOps skills in secure image delivery, private registry integration, and production-ready deployment workflows.

Tools & Technologies

• Harbor (Private Registry)
• Kubernetes (Minikube)
• Docker (with cert trust)
• TLS/SSL (OpenSSL)
• NodePort Services
• YAML + kubectl
• Ubuntu 24.04

Project Walk-through

1. Define a Simple Web App


2. Optimize with Multi-Stage Dockerfile
