Integrating CI/CD Pipeline on AWS EKS With Jenkins, Helm, Prometheus & Grafana, ArgoCD, and Trivy

Building a Secure, Monitored CI/CD Pipeline on AWS EKS with Jenkins, Helm, ArgoCD, Prometheus, Grafana & Trivy

Introduction

Continuous Integration and Continuous Deployment (CI/CD) pipelines are crucial for automating software delivery, but ensuring security and observability is just as important. By integrating Jenkins, Helm, ArgoCD, Prometheus, Grafana, and Trivy, you can build a robust, secure, and monitored GitOps-driven pipeline for Kubernetes applications running on AWS EKS.

This article walks through setting up a secure and fully monitored CI/CD pipeline on AWS EKS, leveraging GitOps principles, automated security scanning, and real-time observability. For an in-depth step-by-step guide, check out my blog: Integrating CI/CD Pipeline on AWS EKS.

Key Components of the CI/CD Pipeline

1. Jenkins: CI/CD Automation

• Automates the build, test, and deployment process.
• Integrates with Kubernetes and container registries.
• Supports plugins for integrating with AWS services, Helm, and GitOps tools.

2. Helm: Kubernetes Package Management

• Manages Kubernetes deployments using Helm charts.
• Simplifies versioning and rollbacks.
• Reduces deployment complexity by managing configuration templates.

3. ArgoCD: GitOps for Kubernetes

• Enables declarative GitOps-based deployments.
• Ensures Kubernetes manifests remain in sync with Git repositories.
• Supports multi-cluster application management and automatic rollbacks.

4. Prometheus & Grafana: Monitoring & Observability

• Prometheus collects Kubernetes and application metrics.
• Grafana visualizes metrics and alerts based on Prometheus data.
• Helps detect anomalies, optimize performance, and provide real-time insights.

5. Trivy: Security Scanning

• Scans container images and Kubernetes clusters for vulnerabilities.
• Provides automated security enforcement in CI/CD pipelines.
• Detects misconfigurations, exposed secrets, and outdated dependencies.

Step-by-Step Setup?

Step 1: Setting Up AWS EKS Cluster

1. Create an IAM Role for EKS: aws iam create-role --role-name eksClusterRole --assume-role-policy-document file://eks-trust-policy.json
2. Create an EKS Cluster: aws eks create-cluster --name secure-eks --role-arn <IAM_ROLE> --resources-vpc-config subnetIds=<SUBNET_IDS>,securityGroupIds=<SECURITY_GROUP_IDS>
3. Configure kubectl to Connect to EKS: aws eks update-kubeconfig --region <AWS_REGION> --name secure-eks

Step 2: Deploy Jenkins on EKS

1. Install Jenkins using Helm: helm repo add jenkins https://charts.jenkins.io helm install jenkins jenkins/jenkins --namespace jenkins --create-namespace
2. Retrieve Admin Password: kubectl get secret --namespace jenkins jenkins -o jsonpath="{.data.jenkins-admin-password}" | base64 --decode
3. Configure Jenkins Plugins: Install necessary plugins such as Kubernetes Plugin, Git Plugin, Docker Pipeline Plugin, and Helm Plugin for seamless integration.

Step 3: Implement GitOps with ArgoCD

1. Install ArgoCD on EKS: kubectl create namespace argocd kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml
2. Log into ArgoCD Web UI: kubectl port-forward svc/argocd-server -n argocd 8080:443
3. Sync Application Manifests from Git: argocd app sync my-k8s-app

Step 4: Integrate Monitoring with Prometheus & Grafana

1. Deploy Monitoring Stack: helm install prometheus prometheus-community/kube-prometheus-stack --namespace monitoring --create-namespace
2. Access Grafana for Visualization: kubectl port-forward svc/prometheus-grafana -n monitoring 3000:80
3. Set Up Alerts in Grafana to notify security and DevOps teams of anomalies.

Step 5: Automate Security Scanning with Trivy

1. Install Trivy Scanner: helm install trivy aquasecurity/trivy-operator --namespace security --create-namespace
2. Run Image Scanning: trivy image <AWS_ACCOUNT_ID>.dkr.ecr.us-west-2.amazonaws.com/my-app:v1

Real-World Use Cases

Use Case 1: Secure Banking Applications

Financial institutions require highly secure deployments with real-time monitoring. By integrating Trivy for security scanning and Prometheus/Grafana for monitoring, banks can ensure compliance with regulations like PCI-DSS.

Use Case 2: Scalable E-Commerce Platforms

E-commerce platforms rely on auto-scaling Kubernetes applications to handle high traffic. Helm simplifies application upgrades, and ArgoCD ensures a zero-downtime deployment strategy.

Use Case 3: Healthcare and Compliance

Healthcare providers need HIPAA-compliant security and continuous monitoring. AWS EKS, combined with RBAC (Role-Based Access Control) and Trivy security scanning, ensures data protection and system integrity.

Use Case 4: DevOps for SaaS Startups

Startups deploying SaaS applications need a cost-efficient, automated CI/CD pipeline. Jenkins automates deployments, ArgoCD maintains version control, and Prometheus alerts DevOps teams on performance bottlenecks.

Conclusion

By integrating Jenkins, Helm, ArgoCD, Prometheus, Grafana, and Trivy, organizations can build a secure, automated, and monitored CI/CD pipeline on AWS EKS. This approach enhances deployment efficiency while ensuring security and observability.
