Controller
‣ 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.
