Then, looking at microK8s for example, you ask a question about addon 
called metallb with quote from their "Why?" at https://metallb.universe.tf/
"""

Kubernetes does not offer an implementation of network load balancers 
(Services of type LoadBalancer) for bare-metal clusters. The 
implementations of network load balancers that Kubernetes does ship with 
are all glue code that calls out to various IaaS platforms (GCP, AWS, 
Azure…). If you’re not running on a supported IaaS platform (GCP, AWS, 
Azure…), LoadBalancers will remain in the “pending” state indefinitely 
when created.

"""

It all makes sense. "Kubernetes" is not an implementation! k8s docs 
direct you towards someone else's hosted implementations. Hm-m.
