DevSecOps Pipeline

Project Overview

The project represents a comprehensive DevSecOps implementation for a Board Game Database web application, strategically deployed on a self-managed Kubernetes infrastructure using Google Cloud Platform (GCP). Leveraging Terraform for infrastructure provisioning, this solution transcends traditional deployment approaches by integrating advanced security, automation, and continuous monitoring practices.
