A comprehensive end-to-end CI/CD infrastructure for containerized applications, featuring AWS infrastructure provisioning, automated configuration management, continuous integration, and GitOps-based deployment to Kubernetes.

This project implements a complete DevOps infrastructure with the following major components:

• EC2 Instance 1 (Master):
  • Hosts Jenkins Master that controls the CI pipeline
  • Configured with Ansible playbooks
• EC2 Instance 2 (Slave):
  • Jenkins Slave node for executing build jobs
  • Handles resource-intensive pipeline tasks
  • Configured with Ansible playbooks
• Supporting Services:
  • S3 Bucket for Terraform state backend
  • CloudWatch for monitoring and logging

• kubeadm Cluster:
  • kubeadm Kubernetes implementation with master + node1
  • Contains dedicated "iVolve" namespace
  • Manages Deployments, Services, and Ingress resources

• Core Components:
  • Application Controller for state management
  • Repository Server for cached repositories
  • API Server for RESTful operations
  • GitOps Engine for synchronization logic
• Workflow:
  • Monitors GitHub repository for manifest changes
  • Automatically syncs configurations to Kubernetes
  • Maintains desired state defined in Git

1. Code is pushed to GitHub repository
2. Jenkins Master detects changes and assigns build job to Slave
3. Jenkins Slave executes pipeline steps:
   • Runs unit tests
   • Creates Docker image
   • Pushes image to registry
   • Updates Kubernetes manifests
   • Commits changes back to Git repository
4. ArgoCD detects manifest changes in repository
5. ArgoCD syncs changes to Minikube cluster
6. Application is deployed/updated in the local environment

• AWS account with appropriate permissions
• Docker installed
• Kubernetes cluster (kubeadm master + node1)
• Git installed
• Basic knowledge of Terraform, Ansible, Jenkins, and Kubernetes
