💾 StorageClasses Create Volumes Automatically

Manual volume creation is tedious. StorageClasses provision volumes dynamically. Specify storage type, size, performance.

📝 StorageClass Examples

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: fast-ssd
provisioner: kubernetes.io/aws-ebs
parameters:
  type: gp3
  encrypted: "true"
  iopsPerGB: "50"
allowVolumeExpansion: true

---
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: standard
provisioner: kubernetes.io/aws-ebs
parameters:
  type: gp2
  encrypted: "true"

---
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: slow-hdd
provisioner: kubernetes.io/aws-ebs
parameters:
  type: st1

🎯 Using StorageClass

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: fast-storage
spec:
  accessModes:
    - ReadWriteOnce
  storageClassName: fast-ssd
  resources:
    requests:
      storage: 10Gi

# When PVC is created, PV is automatically provisioned
# kubectl get pv → shows new volume

# Default StorageClass
kubectl patch storageclass standard -p '{"metadata": {"annotations":{"storageclass.kubernetes.io /is -default -class":"true"}}}'
