 If no external loadbalancer is used, Calico eBPF can also use the localhost loadbalancer option. We are able to do so only if you use the same port for the localhost apiserver loadbalancer and the kube-apiserver. In this case Calico Automatic Host Endpoints need to be enabled to allow services like `coredns` and `metrics-server` to communicate with the kubernetes host endpoint.
