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 #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.

This error saying, u are missing an endpoint to be shown, when there is no route matched. i.e. 404 rule

I think this is related to kubernetes/kubernetes#107720
