Part 1: What is expected from this series?

🔹 Introduction

• Why CI/CD pipelines are critical for modern cloud deployments.

• The importance of integrating security checks, automation, and monitoring.

• A quick overview of the tools used: Jenkins, GitHub, OWASP, SonarQube, Trivy, Docker, Argo CD, Prometheus, and Grafana.

🔹 Architecture Overview

• Developer → GitHub → Jenkins CI/CD → AWS EKS.

• CI pipeline handles code quality, security scans, and image builds.

• CD pipeline handles deployment automation and monitoring.

• Monitoring stack (Prometheus + Grafana) ensures visibility.

• Notifications via email keep stakeholders updated.

🔹 CI Pipeline Stages

1. Code Checkout → Jenkins pulls code from GitHub.

2. Dependency Scanning (OWASP) → Detects vulnerable libraries.

3. Code Quality (SonarQube) → Enforces coding standards and quality gates.

4. Security Scan (Trivy) → Scans filesystem and Docker images for vulnerabilities.

5. Docker Build & Push → Builds container images and pushes to Docker Hub.

6. Version Update → Updates Kubernetes manifests with new image tags.

7. Commit Back to GitHub → Ensures GitOps workflow consistency.

🔹 CD Pipeline Stages

1. Trigger from CI → Jenkins CD job starts.

2. Argo CD Deployment → Syncs manifests from GitHub to AWS EKS.

3. Kubernetes Execution → Deploys updated pods/services.

4. Monitoring:

   • Prometheus → Collects metrics.

   • Grafana → Visualizes dashboards.

5. Notifications → Email alerts on pipeline completion.

🔹 Tools & Integrations

• Jenkins → CI/CD automation.

• GitHub → Source control + GitOps repo.

• OWASP Dependency Check → Security scanning.

• SonarQube → Code quality analysis.

• Trivy → Vulnerability scanning.

• Docker Hub → Image registry.

• Argo CD → GitOps deployment.

• AWS EKS → Managed Kubernetes cluster.

• Prometheus & Grafana → Monitoring and visualization.

• Email (SMTP) → Notifications.
