KinD, nGinx Ingress Controller & Secured gRPC server
summary
Demonstrates an end-to-end mTLS setup: a Golang gRPC server runs with server-side certificates behind an nginx ingress on a KinD cluster and a NodeJs gRPC client presents client certificates to complete mutual TLS. Walks through the exact Kubernetes manifests, nginx TLS passthrough/HTTP2 settings, certificate generation and client/server code changes, and a live demo that verifies successful encrypted calls and mutual authentication between pods. Includes configs and commands used to reproduce.
