IngressControllers created without specifying a spec.endpointPublishingStrategy.loadBalancer.providerParameters.aws.type should use the default specified in the ingresses.config.openshift.io.spec.loadBalancer.platform.aws.type.

When this default is NLB, and an IngressController is created without specifying LB Type, but spec.endpointPublishingStrategy.loadBalancer.providerParameters is NOT empty, the defaulting doesn't work (instead uses the universal default of Classic). But when providerParameters is empty, default works correctly.

    TBD (Need more testing, most likely more version affected)

    100%

    1. oc edit ingresses.config.openshift.io cluster
    2. Set spec.loadBalancer.platform.aws.type to NLB
    3. Create IngressController with providerParameters non-empty, but with no LB Type:
oc apply -f - <<EOF
apiVersion: operator.openshift.io/v1
kind: IngressController
metadata:
  name: nlb
  namespace: openshift-ingress-operator
spec:
  domain: $domain
  replicas: 1
  endpointPublishingStrategy:
    loadBalancer:
      scope: External
      dnsManagementPolicy: Managed
      providerParameters:
        type: AWS
    type: LoadBalancerService
  nodePlacement:
    nodeSelector:
      matchLabels:
        node-role.kubernetes.io/worker: ""
EOF
     

IngressController load balancer will use Classic

IngressController load balancer should use NLB
