I am trying to create a service on kubernetes on openstack cluster with type = LoadBalancer but it fails to create Loadbalancer saying neutron error (below exact error snippet) .

Below is the web.yaml file :

[root]#kubectl create -f web.yaml

apiVersion: v1

 name: web
labels:
  name: web
spec:
 type: LoadBalancer
 ports:
 - port: 80
   targetPort: 3000
   protocol: TCP
selector:
 name: web

[root]#kubectl describe svc web
