I using NodePort service (with kubeadm) to create ingress, the result show below.

NAME          HOSTS                ADDRESS          PORTS   AGE
app-ingress   example.com          10.110.161.218   80      12m

Any detail in ingress.

Name:             app-ingress
Namespace:        default
Address:          10.110.161.218
Default backend:  default-http-backend:80 (<none>)
Rules:
  Host                Path  Backends
  ----                ----  --------
  example.com
                      /my-api   user-api:3000 (172.10.118.201:3000)

How to let the host name example.com accessible on internet?
