Do you know the architecture of Kubernetes — what entities are there, what is the control plane?

Kubernetes is a container orchestration system that manages deployment, scaling, and maintenance of applications.

Main entities of Kubernetes:

• Pod — the smallest deployable unit, containing one or more containers.
• Service — an abstraction that provides stable access to a set of Pods.
• Deployment — manages updates and scaling of Pods.
• Namespace — a virtual cluster within Kubernetes for resource separation.
• ConfigMap and Secret — used for storing configurations and secret data.

Control Plane — a set of components that manage the cluster's state:

• kube-apiserver — the API server through which all components interact.
• etcd — a distributed configuration and state storage.
• kube-scheduler — responsible for assigning Pods to nodes.
• kube-controller-manager — runs controllers that monitor the cluster's state and ensure the desired state.

The Control Plane manages and coordinates all worker nodes where containers run.
