Oracle Container Engine for Kubernetes now automatically enables the ServiceNodeExclusion feature gate on the clusters it creates.

With the ServiceNodeExclusion feature gate enabled on a cluster, you can add the node.kubernetes.io/exclude-from-external-load-balancers label to particular worker nodes to exclude them from the list of backend servers in an Oracle Cloud Infrastructure load balancer backend set. The fewer worker nodes included in a backend set, the faster the load balancer can be updated.

For more information see node.kubernetes.io/exclude-from-external-load-balancers.
