Ingress
In plain terms
A Kubernetes resource managing external access to services.
Going deeper
Ingress routes outside HTTP/HTTPS traffic to internal services with rules for hosts and paths, plus TLS. It's the cluster's smart front door.
Under the hood
Requires an ingress controller (NGINX, Traefik); consolidates routing and TLS termination.
Examples
HTTP routing, TLS termination, path-based routing, NGINX ingress.
Think of it like...
Like a building's reception that directs visitors to the right office based on who they're seeing.
