Have you had experience working with StatefulSet objects in Kubernetes?

Yes, experience with StatefulSet in Kubernetes includes understanding that it is a controller for managing the state of applications that require stable identifiers and persistent storage.

StatefulSet guarantees:

• Unique and stable pod names.
• Ordered creation, updating, and deletion of pods.
• Binding to persistent storage (PersistentVolume).

Example use cases: databases, cache systems, where data integrity and startup order are important.

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: example
spec:
  serviceName: "example-service"
  replicas: 3
  selector:
    matchLabels:
      app: example
  template:
    metadata:
      labels:
        app: example
    spec:
      containers:
      - name: example-container
        image: example-image
        volumeMounts:
        - name: data
          mountPath: /data
  volumeClaimTemplates:
  - metadata:
      name: data
    spec:
      accessModes: ["ReadWriteOnce"]
      resources:
        requests:
          storage: 1Gi

This manifest will create 3 pods with persistent storage and unique names.
