Tech stack:

• Fullstack: JavaScript, React, Node.js (Express), SQL (PostgreSQL)
• Devops: Amazon EKS (Kubernetes), Amazon ECR, Docker, Github Actions (CI/CD)

Instructions

• Use npm run create-cluster to create EKS cluster (eksctl create cluster --name <cluster-name> --region <region_mame> --fargate)
• Make changes to your code
• When code is committed to the main branch:
  • Git commit hash code is used to tag docker image
  • Docker images are built from Dockerfiles (runs npm run build to build app): tagged, built and pushed to ECR repository
  • Kubeconfig file is updated (organize information about clusters, users, namespaces, and authentication mechanisms)
  • Finally changes to application are deployed to Kubernetes cluster by applying the Service and Deployment Manifests
• To delete Kubernetes cluster: npm run delete-cluster
