Advanced Features of Ingress Controllers

SSL/TLS Termination

Ingress Controllers often provide the ability to terminate SSL/TLS encryption at the controller level, offloading the decryption process from individual services. This is achieved by specifying TLS settings in the Ingress resource.

...
tls:
  - hosts:
      - example.com
    secretName: example-tls-secret
...

Path-based Routing and Rewrites

Ingress Controllers support path-based routing, allowing you to direct requests to different services based on the specified paths. Additionally, URL rewrites can be configured to modify the requested path before forwarding it to the backend service.

...
paths:
  - path: /v1
    pathType: Prefix
    backend:
      service:
        name: v1-service
        port:
          number: 80
...

In the dynamic landscape of containerized applications, efficiently orchestrating and managing services is critical. As an effective platform for container orchestration, Kubernetes offers a stable foundation for launching, growing, and overseeing containerized applications. The Ingress controller is a crucial part of Kubernetes that helps with efficient service administration.

We’ll examine the nuances of Kubernetes Ingress controllers in this extensive post, including how they function in service load balancing and routing. To assist you in understanding the principles and implementation specifics, we’ll go over the essentials, explore their functioning mechanisms, and offer practical examples.
