bashWhat is a ReplicaSet and how does it relate to Deployments?
Explanation & Concept
A ReplicaSet's sole purpose is to maintain a stable set of replica Pods running at any given time. Deployments wrap ReplicaSets and manage them during rolling updates.
Code Example
bash
# View ReplicaSets created by a deployment
kubectl get replicasetsHow It Works & Key Takeaways
During a rolling update, a Deployment spins up a new ReplicaSet with the new image version while gradually scaling down the old ReplicaSet.
