Hi @zhouyp520,

the (<error: endpoints "default-http-backend" not found>) error is fine, we don't support default-http-backend. However we might implement this in the future https://github.com/nginxinc/kubernetes-ingress/issues/892

Your problem is in the demo-ingress.yaml file the servicePort is set to 80 but in the hello-node.yaml file the port is defined to 8000. Changing the servicePort: 80 to servicePort: 8000 in the demo-ingress.yaml file should fix your problem.
