Kubernetes Ingress and Service Diagram

Kubernetes Ingress to Service

This Kubernetes diagram traces a web request from the internet to an application. A load balancer receives HTTPS traffic and sends it to an ingress controller. The ingress controller applies a host rule and directs the request to a Kubernetes service. The service selects two web pod endpoints, which use a shared database. This picture helps distinguish ingress routing from service-to-pod routing. It is useful for explaining an application deployment to developers or reviewers. Add namespaces, network policies, or TLS certificates if those details change how traffic is handled. Keep the diagram current when equipment, cable paths, service ownership, or security boundaries change, so it remains useful for planning and operations.
