Manages the deployment and scaling of a set of {{< glossary_tooltip text="Pods" term_id="pod" >}}, and provides guarantees about the ordering and uniqueness of these Pods.

Like a {{< glossary_tooltip term_id="deployment" >}}, a StatefulSet manages Pods that are based on an identical container spec. Unlike a Deployment, a StatefulSet maintains a sticky identity for each of their Pods. These pods are created from the same spec, but are not interchangeable: each has a persistent identifier that it maintains across any rescheduling.

A StatefulSet operates under the same pattern as any other Controller. You define your desired state in a StatefulSet object, and the StatefulSet controller makes any necessary updates to get there from the current state.
