What is an Ingress controller?

Ingress controllers play a crucial role in Kubernetes networking by providing an additional abstraction layer and functionality for managing external access to services within the cluster. Here’s why we need Ingress controllers:

• Single entry point: In Kubernetes, services typically expose applications within the cluster. However, managing access to these services from outside the cluster can become complex, especially as the number of services and routes increases. Ingress controllers act as a single entry point for external traffic, simplifying the management of inbound connections.
• HTTP and HTTPS routing: Ingress controllers can route HTTP and HTTPS traffic to different services based on the request’s path, host, or other attributes. This enables more sophisticated routing configurations, such as directing requests to specific services based on URL patterns or domain names.
• SSL/TLS termination: Ingress controllers...
