we are running our automation over cluster setup regularly from actual status of the branch.
Even though there is no change in configuration (manifest), istio operator changes nodePort on ingress gateway (service of type LoadBalancer) which causes URL downs alerts on defined VS - because underlaying load balancer needs to cope with changed port.
We are using istio 1.7.7.
Similar problem was reported here:
Do you know why the nodePort is being changed?
Do you know about any workaround?
