At a very high level, there are three key concepts:

Pods are the smallest deployable units that can be created, scheduled, and managed. Its a logical collection of containers that belong to an application.

Master is the central control point that provides a unified view of the cluster. There is a single master node that control multiple minions.

Minion is a worker node that run tasks as delegated by the master. Minions can run one or more pods. It provides an application-specific “virtual host” in a containerized environment.
