Kubernetes Ingress & Routing
Configure Ingress resources to provide external access to services, enabling advanced routing and TLS termination.
Get External Access with Ingress
So far, we've used Services like NodePort or LoadBalancer to expose our applications outside the Kubernetes cluster.
While effective, these have limitations for complex routing, host-based rules, or managing TLS certificates for multiple applications.
This is where Ingress comes in! It acts as an entry point for external traffic, offering more advanced routing capabilities.
Ingress vs. Services: Key Differences
Let's clarify the roles:
- Service: Provides stable networking for Pods within the cluster and can expose a single application externally (e.g.,
NodePort,LoadBalancer). - Ingress: Manages external access to multiple Services, offering features like URL routing, host-based routing, and SSL/TLS termination.
Think of Ingress as a smart traffic controller for your external requests.
