Deploying BoardGame on Kubernetes through a CI/CD Pipeline

The primary purpose of this project is to automate the software delivery lifecycle, from code compilation to deployment, thereby accelerating time-to-market, enhancing product quality, and reducing manual errors. The key objectives include:

• Establishing a seamless CI/CD pipeline using Jenkins to automate various stages of the software delivery process.
• Integrating essential DevOps tools such as Maven, SonarQube, Trivy, Nexus Repository, Docker, Kubernetes, Prometheus, and Grafana to ensure comprehensive automation and monitoring.
• Improving code quality through static code analysis and vulnerability scanning.
• Ensuring reliable and consistent deployments on a Kubernetes cluster with proper load balancing.
• Facilitating timely notifications and alerts via email integration for efficient communication and incident management.
• Implementing robust monitoring and alerting mechanisms to track system health and performance.

Tools Used

• Jenkins: Automation orchestration for CI/CD pipeline.
• Maven: Build automation and dependency management.
• SonarQube: Static code analysis for quality assurance.
• Trivy: Vulnerability scanning for Docker images.
• Nexus Repository: Artifact management and version control.
• Docker: Containerization for consistency and portability.
• Kubernetes: Container orchestration for deployment.
• Gmail Integration: Email notifications for pipeline status.
• Prometheus and Grafana: Monitoring and visualization of system metrics.
• AWS: Creating virtual machines.

Deployment Phases

Phase 1: Infrastructure Setup

• Built a robust network environment for seamless communication.
