pathType field

As explained in Acing the Certified Kubernetes Administrator Exam, Second Edition

A path type is an Ingress rule setting that specifies how a URL path is matched.

Use pathType in an Ingress rule to control how an HTTP URL path matches before traffic is forwarded to a Service. section 6.3

Choose the matching behavior required by the route:

Host-specific path rules

Set pathType: ImplementationSpecific for hello.com at /, routing to hello-svc on port 80; set pathType: Exact for app.hello.com at /, routing to nginx on port 8080.
