What are Kubernetes volumes and how do they differ from Docker volumes?

Kubernetes volumes provide persistent storage that outlives individual containers and enables data sharing between containers in a pod.\n\nKey Differences from Docker Volumes:\n• Pod-scoped: Volumes exist at pod level, not container level\n• Multiple types: emptyDir, hostPath, PV/PVC, cloud storage\n• Lifecycle management: Tied to pod lifecycle\n• Cross-container sharing: All containers in pod can access\n• Storage classes: Dynamic provisioning support\n\nVolume Types:\n• emptyDir: Temporary storage, deleted with pod\n• hostPath: Mount host directory (not recommended for production)\n• PersistentVolume: Cluster-wide storage resource\n• ConfigMap/Secret: Configuration and sensitive data\n• Cloud volumes: AWS EBS, GCP PD, Azure Disk\n\nExample PVC:\napiVersion: v1\nkind: PersistentVolumeClaim\nmetadata:\n name: app-storage\nspec:\n accessModes: [ReadWriteOnce]\n resources:\n requests:\n storage: 10Gi\n\nBest Practices:\n• Use PVCs for persistent data\n• Choose appropriate access modes\n• Implement backup strategies\n• Monitor storage usage
