help request: How to use Ingress CRD with host and port about apisix HOT 3 OPEN

you can write custom k8s service and ep at your own.

from apisix.

AFAIK, it's not possible to do this. @zlhgo's suggestion seems right.

EDIT:

seems like there is a way: https://apisix.apache.org/docs/ingress-controller/1.6.0/tutorials/external-service/#external-domain-upstream

Thanks for your suggestion, but it doesn't solve my problem. When I configure ApisixUpstream using ip and port it is wrong:
Domain must match lowercase RFC 1123 subdomain. a lowercase RFC 1123 subdomain must consist of lower case alphanumeric characters,
This does not comply with the DNS specification. Can you give me a demo of the upstream service configuration IP and port, like this:

spec:
  externalNodes:
  - type: Domain
    name: 192.168.1.80:8080

from apisix.
