Overview
A ReplicaSet is a workload resource aimed at maintaining a stable set of replica Pods running at any given time, guaranteeing the availability of a specified number of identical Pods.
Replicaset Controller
The replicaset controller is part of the controller manager. The controller implements a watch loop that is constantly observing the cluster making sure that the current state matches the desired state - the desired number of pods.
Scaling
A ReplicaSet has a Scale sub-resource, allowing it to be controlled by a horizontal pod autoscaler.
