What Is Kubernetes?
Briefly

The Kubernetes master operates as the control plane and primary access point for managing clusters and container deployments. It stores configuration data in etcd, accessible by all nodes for maintaining container states. Communication occurs via the kube-apiserver, ensuring synchronization between etcd and running containers. Control loops are managed by the kube-controller-manager, which oversees replicas, deployments, and node health. The kube-scheduler assigns workloads based on node resources, while the cloud-controller-manager maintains cloud-agnostic services between Kubernetes and cloud provider APIs.
The Kubernetes master acts as the central control plane for managing clusters, maintaining configurations, and ensuring that nodes correctly handle container deployments.
The kube-apiserver is the main access point that communicates with the cluster, ensuring the configuration in etcd aligns with container deployments.
