What is a StatefulSet?

Answer from AI
StatefulSet is an object in Kubernetes designed to manage the state of applications that require maintaining a unique identity and stable network identifiers. Unlike Deployment, which is suitable for stateless applications, StatefulSet provides:
- Unique and stable pod names
- Stable network identifiers (DNS)
- Ordered creation, updating, and deletion of pods
- Persistent storage for each pod via PersistentVolume
An example of using StatefulSet includes databases, cache systems, where data integrity and startup order are important.
