ReplicationController

‣ Endpoint with DNS name ‣ Logical group of Pods ‣ Policy how to access the Pods

‣ Atomic unit of orchestration and scheduling

‣ Group of co-located containers(one node, one lifecycle)

‣ Containers share an unique IP,persistent volumes and env vars ‣ Controls Pod lifecycle

‣ Ensures that a defined nbr. of Pod instances is running

new gen: Replica Set

Deployment: Declarative update (target state description) for Pods and Replica Sets.
