What is the relationship between pods and deployments in Kubernetes?

• A. A deployment manages replicas and rollout of pods.
• B. A pod manages the replicas and rollout of deployments.
• C. A deployment is a physical node.
• D. A pod is a type of deployment strategy.

Answer: (A)

In Kubernetes, the deployment is a higher-level controller that defines the desired state for a set of pods. Pods are the actual running instances of containers. The deployment ensures a specified number of pods are running (replicas) and controls how updates are rolled out. It does this by creating and managing ReplicaSets, which in turn create the pods. If a pod crashes, the deployment replaces it to maintain the replica count. During a rollout, changing the pod template triggers a new ReplicaSet and a gradual replacement of old pods with new ones, providing a controlled update. A pod cannot manage deployments, and a deployment is not a physical node or a deployment strategy. So, the best description is that a deployment manages replicas and rollout of pods.
