🔥 What I Implemented

✅ Go backend using net/http, HTML templates & local file storage
✅ Multi-stage Dockerfile with non-root user
✅ Minikube setup with real K8s cluster
✅ Kubernetes Deployment, Service, Ingress + NGINX Ingress Controller
✅ Domain mapping via hosts file (go-wiki.local) + minikube tunnel
✅ File permission fix using securityContext
✅ Helm Chart to package the app
✅ CI with GitHub Actions, CD via Argo CD (GitOps)
