Exercise 6.6 loadBalancer external IP in pending

Hello

During exercise 6.6 I am doing something wrong with my load balancer config; While the load balancer appears working correctly (I am able to access the nginx server from outside the node by web and by curl locally using both service and pod IPs), the service is listed as having a pending external IP and I dont know if this is normal (I don't see necesarly to specify the node IP as external IP in the yaml). Any help?

Yaml:
apiVersion: v1
kind: Service
metadata:
name: lb
spec:
selector:
type: nserver
ports:

• port: 80
  targetPort: 80
  protocol: TCP
  nodePort: 31000
  type: LoadBalancer

kubectl get svc:
lb LoadBalancer 10.111.157.39 <pending> 80:31000/TCP 9m18s

kubectl describe service lb
Name: lb
Namespace: default

Selector: type=nserver

NodePort: 31000/TCP

Thanks in advance!
