Description Maysa Macedo 2020-09-03 11:34:54 UTC
Description of problem:

If a loadBalancerIP is defined on the Service it should be associated
to the created Load Balancer. However, that is not happening as
the LB CRD can be missing the lb_ip field definition, consequently
a new Floating IP, different from the one specified on the Service spec,
is allocated to the Load Balancer.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Create a service with loadbalancerIP defined and pointing to an existing FIP, like:

apiVersion: v1
kind: Service
metadata:
  labels:
    run: demo
  name: demo
  namespace: default
spec:
  ports:
  - nodePort: 31089
    port: 80
    protocol: TCP
    targetPort: 8080
  selector:
    run: demo
  type: LoadBalancer
  loadBalancerIP: 172.24.4.73

2. Check the LB is associated to that loadBalancerIP
3.

Actual results:


Expected results:
