Hi,

I'm running minikube on one Centos server, and create kubernetes cluster for running Seldon-server.

I tried to expose the seldon-server service to the static public IP address (10.32.42.214 as shown above) by exposing on nodePort but it doesn't seem to work. Seems like it pertains to the 172.17.0.15 IP instead:

# kubectl describe service seldon-server

Name: seldon-server

Namespace: default

Labels: name=seldon-server

service=seldon

Selector: name=seldon-server

Type: NodePort

IP: 10.0.0.20

External IPs: 10.32.42.214

Port: api 80/TCP

NodePort: api 30015/TCP

Endpoints: 172.17.0.15:8080

Port: rpc 5000/TCP

NodePort: rpc 30017/TCP

Endpoints: 172.17.0.15:5000

Session Affinity: None

No events.

# kubectl get -o template po seldon-server-2669694256-tf60n --template={{.status.podIP}}

172.17.0.15

Can anyone help on this? It would be greatly appreciated!

Thanks,

James
