Overview
Used for stateful application components, where the application component relies on access to "stable" file storage to maintain state between restarts. As such, local volumes that are directly attached to node hosts, can be used. A StatefulSet and the individual pods the StatefulSet manages are registered with the cluster's DNS service.
A stateful set makes sure pods are rescheduled in such a way that they retain their identity and state.
