Master: The machine that controls Kubernetes nodes. This is where all task assignments originate.
Node: These machines perform the requested, assigned tasks. The Kubernetes master controls them.
Pod: A group of one or more containers deployed to a single node. All containers in a pod share an IP address, IPC, hostname, and other resources. Pods abstract network and storage away from the underlying container. This lets you move containers around the cluster more easily.
kubectl: This is the command line configuration tool for Kubernetes.
