Cannot update haproxy service parameters

MySQL & MariaDB Percona Operator for MySQL
1

I’m using the Percona Operator for MySQL based on Percona XtraDB Cluster and I expose the haproxy using the cluster resource.

I am able to set up the service fine with the following configuration:

haproxy:
    serviceType: LoadBalancer
    replicasServiceType: LoadBalancer
    serviceAnnotations:
      # primeiras duas annotations são tentativa de consertar bug quando source range é modificado
      # e controlador não permite porque recebe loadBalancerClass null
      service.beta.kubernetes.io/aws-load-balancer-scheme: internet-facing
    replicasServiceAnnotations:
      service.beta.kubernetes.io/aws-load-balancer-scheme: internet-facing
    loadBalancerSourceRanges:
      - 190.0.0.0/8
      - 189.0.0.0/8
      - 187.0.0.0/8
      - 186.0.0.0/8
      - 10.0.0.0/8
      - 200.234.208.6/32
    replicasLoadBalancerSourceRanges:
      - 190.0.0.0/8
      - 189.0.0.0/8
      - 187.0.0.0/8
      - 186.0.0.0/8
      - 10.0.0.0/8
      - 200.234.208.6/32
    externalTrafficPolicy: Local # para preservar Source IP e não causar drop na Network Policy
    replicasExternalTrafficPolicy: Local

This works fine at first install. However, if I later try to modify the service, for example altering the loadBalancerSourceRanges, the pxc operator logs the error: "error": "cluster4-haproxy upgrade error: Service \"cluster4-haproxy\" is invalid: spec.loadBalancerClass: Invalid value: \"null\": may not change once set"

Any way to work around this issue? I noticed that I can delete the Service and it eventually gets recreated, but I would like a solution that works without needing the extra step.

Hi @gmautner,

Did you check what spec.loadBalancerClass value was assigned to it after you first created it? You could add that to your yaml, with the same value, and see if that helps clear out these errors.
