This project challenged me to design and implement a full CI/CD pipeline using modern DevOps tools and best practices across provisioning, automation, containerization, orchestration, and deployment.

Here’s what I built:

✅ Infrastructure as Code with Terraform
- Designed modular infrastructure: VPC, subnets, and EC2 instances (Jenkins Master & Agent)
- Provisioned an Amazon EKS cluster for container orchestration
- Configured S3 as a remote backend for state management
- Integrated CloudWatch and SNS for centralized monitoring and alerting

✅ Configuration Management with Ansible
- Automated setup of Jenkins Master & Agent on EC2 instances
- Preconfigured Jenkins with required plugins, users, and BlueOcean UI
- Developed reusable Ansible roles for installing Docker, Git, and system packages
- Used dynamic EC2 inventory for scalable configuration management

✅ CI/CD Pipeline with Jenkins
- Multi-stage pipeline: Code Push → Test → Docker Build → Push → Manifest Update → Deploy
- Jenkins Agent handles builds; Master controls orchestration
- Automatically updates Kubernetes manifests after each build

✅ Containerization with Docker
- Dockerized a Flask web app using a lightweight Python Alpine base image
- Applied security scanning and image optimization using Trivy

✅ Kubernetes Deployment on AWS EKS
- Deployed workloads to EKS cluster using Kubernetes manifests
- Created a dedicated namespace (ivolve) for application isolation
- Exposed services with LoadBalancer

✅ GitOps with ArgoCD
- Implemented automated sync between GitHub and EKS cluster
- ArgoCD ensures the desired state is always reflected in production
- Full GitOps lifecycle with Application Controller and Repo Server

✅ Monitoring & Observability
- Set up CloudWatch dashboards, logs, and alarms
- Enabled email notifications via SNS for critical events

Here’s a quick breakdown of how to learn Kubernetes, broken down into key categories.

Same same but different🙂

📘 Master Kubernetes Core Components with This One Powerful Infographic

Ever felt overwhelmed by the Kubernetes ecosystem? Here's your cheat sheet – a Periodic Table of Kubernetes essentials! 🔍

This visual breakdown simplifies the building blocks of Kubernetes — from core components to networking, workload objects, observability, and more.

✅ Must-know categories for every DevOps/Platform Engineer:

⚙️ Core Components (API Server, etcd, Scheduler, Controller Manager)
📦 Workload Objects (Pods, Deployments, Jobs, DaemonSets)
🔐 Security & Access Control (RBAC, ServiceAccounts, Roles)
🔗 Networking (Services, Ingress)
🔍 Observability (Logging, Metrics Server)
🔧 Configuration & Storage (Secrets, ConfigMaps, PVs, SCs)

Whether you're deploying microservices or managing a hybrid cloud, understanding these elements is crucial for building a resilient, scalable, and secure Kubernetes environment.

🛠️ This periodic table makes it easier for DevOps engineers, SREs, and platform teams to visualize and navigate Kubernetes fundamentals.
