The machines in the Kubernetes cluster are each given a role within the Kubernetes ecosystem. One server (or a small group in highly available deployments) functions as the master server. This server acts as a gateway for the cluster by exposing an API for users and clients, health checking other servers, deciding how best to split up and assign work (known as “scheduling”), and orchestrating communication between other components. The master server acts as the primary point of contact with the cluster and is responsible for most of the centralized logic Kubernetes provides. The other machines in the cluster are designated as nodes.

[KUB]$ kubectl get nodes
NAME STATUS ROLES AGE VERSION
minikube Ready master 1d v1.10.0

[KUB]$ kubectl cluster-info
Kubernetes master is running at https://192.168.99.100:8443
KubeDNS is running at https://192.168.99.100:8443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use ‘kubectl cluster-info dump’.
