Explain the meaning of "http", "host" and "backend" directives

Question

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: someapp-ingress
spec:
  rules:
  - host: my.host
    http:
      paths:
      - backend:
          serviceName: someapp-internal-service
          servicePort: 8080

Answer 1

host is the entry point of the cluster so basically a valid domain address that maps to cluster's node IP address

the http line used for specifying that incoming requests will be forwarded to the internal service using http.

backend is referencing the internal service (serviceName is the name under metadata and servicePort is the port under the ports section).
