Introduction
The Microk8s apiserver validates and configures data for the api objects which include pods, services, replication controllers, and others. The API server services the REST operations and provides the frontend to the cluster shared state through which all other components interact.
Starting with release 1.21, daemon-apiserver was consolidated into daemon-kubelite.
The apiserver daemon is started using the arguments in ${SNAP_DATA}/args/kube-apiserver. The service configuration is described in full in the upstream kube-apiserver documentation .
