Key Concepts

Persistent Volumes

Cluster-level storage resources that can be provisioned and managed.

  • • Volume lifecycle management
  • • Access modes (RWO, ROX, RWX)
  • • Reclaim policies (Retain, Delete, Recycle)
  • • Storage capacity and limits

Volume Claims

User requests for persistent storage with specific requirements.

  • • Storage size requests
  • • Access mode requirements
  • • Storage class selection
  • • Binding and mounting

Storage Classes

Dynamic provisioning of persistent volumes with different characteristics.

  • • Dynamic volume provisioning
  • • Provisioner configuration
  • • Storage parameters
  • • Default storage classes

Volume Snapshots

Point-in-time copies of persistent volumes for backup and restore.

  • • Snapshot creation and management
  • • Snapshot classes and policies
  • • Restore from snapshots
  • • Backup strategies

Storage Types

Local Storage

Direct access to node storage for high-performance applications.

High Performance

Network Storage

Shared storage accessible from multiple nodes in the cluster.

Shared Access

Cloud Storage
