Deployments and ReplicaSets are closely related in Kubernetes. A Deployment is a higher-level abstraction that manages ReplicaSets and provides declarative updates to Pods. When you create or update a Deployment, Kubernetes automatically creates or updates the underlying ReplicaSet to match the desired state specified in the Deployment.
How are ReplicaSets and Deployments related?
A. Deployments manage ReplicaSets and provide declarative updates to Pods.
B. ReplicaSets manage stateful applications, Deployments manage stateless applications.
C. Deployments are runtime instances of ReplicaSets.
D. ReplicaSets are subsets of Jobs and CronJobs which use imperative Deployments.
Deployments are higher-level abstractions in Kubernetes that manage ReplicaSets.ReplicaSets, on the other hand, are lower-level controllers responsible for maintaining a specified number of identical Pods to ensure high availability and fault tolerance. ReplicaSets are used by Deployments to manage the lifecycle of Pods, including scaling, rolling updates, and maintaining a desired number of replicas.
