End-to-End-DevSecOps-Kubernetes

Advanced End-to-End DevSecOps Kubernetes 3-Tier Project using AWS EKS, ArgoCD, Prometheus, Grafana, and Jenkins

Project Overview: AWS DevOps Pipeline with Jenkins, EKS, and ArgoCD

This project involves setting up a comprehensive DevOps pipeline on AWS, leveraging Jenkins, EKS, and ArgoCD to automate and manage infrastructure and deployment processes. Below is a detailed plan covering each key aspect of the project:

1. IAM User Setup

Objective: Create an IAM user with permissions required for deploying and managing resources.

Steps:

• Log in to the AWS Management Console.
• Navigate to the IAM (Identity and Access Management) service.
• Create a new IAM user with programmatic access.
• Attach necessary policies (e.g., AmazonEC2FullAccess, AmazonEKSFullAccess, AmazonS3FullAccess, etc.) to the IAM user.
• Save the Access Key ID and Secret Access Key for future use.

2. Infrastructure as Code (IaC)

Objective: Use Terraform and AWS CLI to provision the Jenkins server on AWS.

Steps:

• Install Terraform and AWS CLI on your local machine.
• Write a Terraform script to create an EC2 instance for Jenkins.
• Define security groups, IAM roles, and key pairs within the Terraform script.
• Run terraform init, terraform plan, and terraform apply to provision the infrastructure.

3. Jenkins Server Configuration

Objective: Install and configure Jenkins and associated tools on the EC2 instance.

Steps:

• SSH into the EC2 instance.
• Install Docker: sudo apt-get install docker.io.
• Install Jenkins: Follow the Jenkins installation guide for Ubuntu.
• Install Sonarqube, Terraform, Kubectl, AWS CLI, and Trivy.
• Sonarqube: Use Docker to run Sonarqube.
• Terraform and AWS CLI: Install via package managers or manually.
• Kubectl: Follow the installation guide from Kubernetes.
• Trivy: Install Trivy using instructions from the Trivy website.

4. EKS Cluster Deployment

Objective: Create an Amazon EKS cluster using eksctl.

Steps:

• Install eksctl on the Jenkins server.
• Use eksctl create cluster to provision the EKS cluster.
• Verify cluster creation by running kubectl get nodes.

5. Load Balancer Configuration

Objective: Configure an AWS Application Load Balancer (ALB) for the EKS cluster.

Steps:

• Set up an ALB Ingress Controller in the EKS cluster.
• Define an Ingress resource in your Kubernetes configuration to manage routing.

6. Amazon ECR Repositories

Objective: Create private Docker repositories on Amazon ECR.

Steps:

• Navigate to the ECR service in the AWS Management Console.
• Create repositories for frontend and backend Docker images.
• Configure repository policies and permissions.

7. ArgoCD Installation

Objective: Install and configure ArgoCD for continuous delivery and GitOps.

Steps:

• Install ArgoCD using Helm or kubectl.
• Access the ArgoCD web UI and configure it with necessary permissions.
• Connect ArgoCD to your Git repository for application deployment.

8. Sonarqube Integration

Objective: Integrate Sonarqube for code quality analysis.

Steps:

• Configure Jenkins pipelines to include Sonarqube analysis steps.
• Set up Sonarqube scanner within Jenkins jobs.
• Review Sonarqube reports for code quality insights.

9. Jenkins Pipelines

Objective: Create Jenkins pipelines to deploy frontend and backend code.

Steps:

• Define Jenkinsfiles for backend and frontend applications.
• Set up stages for building, testing, and deploying Docker images to ECR.
• Configure deployment to the EKS cluster.

10. Monitoring Setup

Objective: Implement monitoring for the EKS cluster using Helm, Prometheus, and Grafana.

Steps:

• Install Helm on the Jenkins server.
• Deploy Prometheus and Grafana using Helm charts.
• Configure monitoring dashboards in Grafana for EKS metrics.

11. ArgoCD Application Deployment

Objective: Use ArgoCD to deploy a Three-Tier application.

Steps:

• Define ArgoCD application manifests for database, backend, frontend, and ingress components.
• Apply these manifests via ArgoCD to manage deployments and updates.

12. DNS Configuration

Objective: Configure DNS settings to make the application accessible via custom subdomains.

Steps:

• Set up Route 53 hosted zones and records for your domain.
• Configure DNS settings to point to the ALB or Ingress controller.

13. Data Persistence

Objective: Ensure data persistence for database pods using persistent volumes and claims.

Steps:

• Define PersistentVolume (PV) and PersistentVolumeClaim (PVC) resources in Kubernetes.
• Configure your database deployment to use these PVCs.

14. Conclusion and Monitoring

Objective: Summarize achievements and monitor the EKS cluster’s performance.

Steps:

• Review the project setup and highlight key accomplishments.
• Continuously monitor the EKS cluster’s performance using Grafana dashboards.
