Practice projects for DevOps Engineer
Automated CI/CD Pipeline with Docker and AWS ECR
Build a basic CI/CD pipeline using GitHub Actions that automatically builds a simple Python Flask application, runs unit tests, packages it into a Docker container, pushes the image to AWS ECR, and deploys it to a single-node Kubernetes cluster (minikube or EKS). Includes writing a basic Terraform script to provision the ECR repository and IAM roles.
Multi-Environment Infrastructure Deployment with GitOps and Auto-Scaling
Design and implement a production-grade multi-environment (dev, staging, prod) infrastructure on AWS using Terraform modules for EKS, VPC, RDS, and ALB. Set up a GitOps workflow using ArgoCD for Kubernetes deployments with Helm charts. Write Python Lambda functions for automated cost-optimization (e.g., scaling down non-prod environments at night via EventBridge). Implement Kubernetes HPA and cluster autoscaler with proper resource requests and limits, plus a CI/CD pipeline that enforces environment promotion gates with automated smoke tests.
