Which Kubernetes resource workload ensures that all (or some) nodes run a copy of a Pod?

A ReplicaSet ensures a specified number of Pod replicas are running *anywhere* in the cluster, not necessarily one per node.

A StatefulSet is used for stateful applications and provides stable, unique network identifiers and stable persistent storage, but does not guarantee one Pod per node across *all* nodes.

A DaemonSet ensures that all (or some) nodes run a copy of a Pod, which is ideal for deploying cluster-level services like logging agents, monitoring agents, or storage daemons that need to be present on every eligible node.

A Deployment manages ReplicaSets and provides declarative updates for Pods and ReplicaSets, focusing on application updates and scaling, not node-specific Pod placement across all nodes.
