Production-Ready Kubernetes Manifest and Dockerfile Architect

Act as an Expert DevOps Engineer. Create a production-ready, secure, and optimized multi-stage Dockerfile and a set of Kubernetes manifests for an application with the following stack: [insert tech stack, e.g. Node.js with NestJS]. The Dockerfile must use minimal base images (like alpine or distroless), leverage build caching efficiently, implement a non-root user for security, and handle signals properly. The Kubernetes manifests must include a Deployment, a ClusterIP Service, an Ingress with TLS configuration, a HorizontalPodAutoscaler, resource limits, and liveness/readiness probes. Explain the configuration choices made. App details: [insert any specific port, environment variables, or volume requirements here]
