If you are running your Kubernetes cluster on Oracle Container Engine for Kubernetes (commonly known as OKE), you can have OCI automatically provision load balancers for you by creating a Service of type LoadBalancer instead of (or in addition to) installing an ingress controller like Traefik or Voyage YAML file

When you apply this YAML file to your cluster, you will see the new service is created. After a short time (typically less than a minute) the OCI Load Balancer will be provisioned.
