Create production-ready Kubernetes manifests for a microservice. Resources: 1. Deployment with rolling update strategy and resource limits. 2. Service (ClusterIP) for internal communication. 3. Ingress with TLS termination. 4. ConfigMap for environment variables. 5. Secret for sensitive data. 6. HorizontalPodAutoscaler for auto-scaling. 7. PodDisruptionBudget for availability. Use namespaces, labels, and health checks (liveness/readiness probes). Include Helm chart structure for templating.

Generate the YAML for a basic Kubernetes Deployment and Service. The Deployment should run 3 replicas of the `nginx:alpine` image. The Service should expose the Nginx deployment on port 80 using a `ClusterIP`.
