Consider the following Kubernetes Deployment:With the ReplicaSet:And the Pods:What happens if one of the Pods...

In Kubernetes, a Deployment manages ReplicaSets and ensures that the specified number of replicas for a given Pod is always maintained. If a Pod managed by a ReplicaSet is terminated (e.g., using the command kubectl delete pod ), the ReplicaSet detects the discrepancy in the desired state (number of replicas) and the actual state. As a result, the ReplicaSet will immediately create a new Pod to replace the terminated one and maintain the desired number of replicas.

Deployment Management: A Kubernetes Deployment is responsible for maintaining the desired state of Pods through ReplicaSets.

ReplicaSet Functionality: A ReplicaSet ensures that a specified number of Pod replicas are running at all times.

Pod Termination: When a Pod is terminated, the ReplicaSet notices the reduction in the number of running Pods.

Replacement Pod Creation: To restore the desired state, the ReplicaSet automatically creates a new Pod to replace the terminated one.
