Question 1

What is the primary role of the Kubernetes Ingress resource?

Accepted Answer

Expose HTTP/HTTPS routes from outside the cluster to Services

Answer

An Ingress resource defines rules that route external HTTP and HTTPS traffic to internal cluster Services based on host names and URL paths.

Question 2

What component actually processes Ingress rules and routes traffic accordingly?

Accepted Answer

Ingress Controller

Answer

An Ingress Controller (e.g., nginx-ingress or Traefik) is a pod that watches Ingress resources and configures the underlying proxy to fulfill the routing rules.

Question 3

In an Ingress spec, which field allows you to route traffic to different Services based on the URL path?

Accepted Answer

rules.http.paths

Answer

The rules[].http.paths array lets you map specific URL paths (e.g., /api, /static) to different backend Services within a single Ingress resource.

Question 4

How do you configure TLS termination for an Ingress resource?

Accepted Answer

Set spec.tls with a secretName referencing a TLS Secret

Answer

The spec.tls field references a Kubernetes Secret of type kubernetes.io/tls containing the certificate and key, enabling TLS termination at the Ingress.

Question 5

What happens when an Ingress resource has no matching rule for an incoming request?

Accepted Answer

The request is routed to the defaultBackend

Answer

Unmatched requests fall through to the defaultBackend defined in the Ingress (or the controller's global default), which typically returns a 404 response.
