help request: How to use Ingress CRD with host and port

[Richard0706]

Description

About apisix's ingress crd,I know that it can be configured like this:

apiVersion: apisix.apache.org/v2
kind: ApisixRoute
metadata:
  name: httpbin-route
spec:
  http:
    - name: route-1
      match:
        hosts:
          - local.httpbin.org
        paths:
          - /*
      backends:
        - serviceName: httpbin
          servicePort: 80

But I need to configure my upstream node, it is not a k8s service，how can i do it，like this：

apiVersion: apisix.apache.org/v2
kind: ApisixRoute
metadata:
  name: httpbin-route
spec:
  http:
    - name: route-1
      match:
        hosts:
          - local.httpbin.org
        paths:
          - /*
      backends:
        - host: 192.168.1.80
          port: 8090

this can't possibly work！apisix.apache.org/v2，does it have the ability to configure endpoints?
I know I can define an upstream service with host and port ，and then use CRD, but I don't want to do that. I need your help.

Environment

• APISIX version (run apisix version):3.2 LTS
• Operating system (run uname -a):
• OpenResty / Nginx version (run openresty -V or nginx -V):
• etcd version, if relevant (run curl http://127.0.0.1:9090/v1/server_info):
• APISIX Dashboard version, if relevant:
• Plugin runner version, for issues related to plugin runners:
• LuaRocks version, for installation issues (run luarocks --version):

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

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
