KubeOps: Enterprise Microservices GitOps & Service Mesh Deployment Pipeline

---

🚀 Enterprise Resume Project Overview

KubeOps is an end-to-end, production-grade DevOps & Cloud Infrastructure project demonstrating Infrastructure as Code (IaC) via Terraform, automated microservice containerization, CI/CD automation via GitHub Actions, continuous delivery with ArgoCD GitOps, service mesh canary deployment with Istio, Helm Chart packaging, security governance via OPA Gatekeeper & HashiCorp Vault, stateful database orchestration with PostgreSQL StatefulSets, and full observability using Prometheus & Grafana.

---

📌 CV / Resume Bullet Points

• Provisioned Cloud Infrastructure via Terraform (IaC): Automated multi-AZ VPC, subnets, IAM OIDC roles, and AWS EKS cluster deployment with automated Helm operator bootstraps.
• Containerized Multi-Service Architecture: Orchestrated Node.js Express & Python Flask microservices alongside PostgreSQL StatefulSets and Redis caching on Kubernetes.
• Configured Service Mesh & Canary Traffic Management (Istio): Defined VirtualService and DestinationRule specs to execute zero-downtime 90/10 traffic shifting and enforced strict mTLS encryption.
• Automated CI/CD Pipeline & Security Scanning: Integrated GitHub Actions for Docker Buildx multi-arch compilation, Trivy vulnerability audits, and automated GitOps state syncs.
• Enforced Security & Policy Governance (OPA Gatekeeper): Designed ConstraintTemplates disallowing root execution and injected dynamic secrets via HashiCorp Vault.
• Observability & Health Telemetry: Created custom Prometheus Alertmanager rules (High CPU, CrashLoopBackOff) and dynamic Grafana cluster dashboards.
