Ingresses

🚀 What It Does

Ingress is a Kubernetes API object that manages external access to services within a cluster, typically over HTTP or HTTPS. It acts as a smart router that directs incoming traffic to the appropriate service based on rules you define.

🧩 Key Features

• Path-based routing: Route traffic based on URL paths (e.g., /api → service A, /web → service B).
• Host-based routing: Route based on domain names (e.g., api.example.com → service A).
• TLS termination: Handle HTTPS traffic and manage SSL certificates.
• Centralized access control: Apply authentication, rate limiting, and other policies at the edge.

⚙️ How It Works

1. You define an Ingress resource with routing rules.
2. An Ingress Controller (like Nginx, Traefik, or cloud-native ones) watches for these rules and configures the underlying load balancer or proxy.
3. External traffic hits the Ingress Controller, which then routes it to the correct Service, which in turn forwards it to the appropriate Pods.
