proxy-public is none

[bpfrd]

Hi I tried to deploy the basic scripts. But the proxy-public external IP is always none. Shouldn't be the the same as the address of ingress service? I'm wondering how we can fix it?

[centos@master-01 basic]$ kubectl get svc
NAME           TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)    AGE
kubernetes      ClusterIP   ip1       <none>        443/TCP    8m7s
proxy-public   ClusterIP   ip2    <none>        80/TCP     56s
proxy-api        ClusterIP   ip3   <none>        8001/TCP   56s
hub                 ClusterIP   ip4   <none>        8081/TCP   56s
[centos@master-01 basic]$ kubectl get ingress
NAME              CLASS     HOSTS   ADDRESS     PORTS   AGE
jupyter-ingress   traefik   *       ip5   80      7s

What version of k3s are you using? I haven't updated this in a while, I'll check & respond.

Thanks for your response. I'm using

[centos@master-01 z2jh]$ k3s -v
k3s version v1.28.4+k3s2 (6ba6c1b6)
go version go1.20.11

Just a general question: even with the default z2jh config file (except for replacing proxy->service->LoadBalancer with NodePort) I have the below services running:

[centos@master-01 z2jh]$ kubectl get svc
NAME           TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)        AGE
kubernetes     ClusterIP   10.43.0.x       <none>        443/TCP        15m
hub            ClusterIP   10.43.70.x    <none>        8081/TCP       8m47s
proxy-api      ClusterIP   10.43.187.x    <none>        8001/TCP       8m47s
proxy-public   NodePort    10.43.164.x   <none>        80:31533/TCP   8m47s

If i do curl http://nodeportip/hub on the server it creates a new line in the logs

kubectl logs pod/hub-55c994b5b5-xh7l6 | tail
>[I 2023-12-13 17:23:16.088 JupyterHub log:191] 301 GET /hub -> /hub/

or my master node IP curl my-master-node-ip:31533/hub/xxxxxx also works too.
So it's working locally.
But I can't access jupyterhub in my local browser using http://my_public_ip:31533. I'm not familiar with networking but there seems to be a problem there. I was wondering how I can fix it?

Thanks
