StorageClass

StorageClass allows PVCs to provision storage automatically, removing the need to pre-create PVs.

Key fields

• provisioner: storage plugin
• parameters: storage options
• reclaimPolicy: cleanup behavior

Minimal example

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: fast
provisioner: csi.example.com
parameters:
  type: ssd
reclaimPolicy: Delete

Tips

• Two tiers (fast/standard) are usually enough
• Review reclaim policy and backups in production

Practical notes

• Start with a quick inventory: kubectl get nodes, kubectl get pods -A, and kubectl get events -A.
• Compare desired vs. observed state; kubectl describe usually explains drift or failed controllers.
• Keep names, labels, and selectors consistent so Services and controllers can find Pods.

Quick checklist

• The resource matches the intent you described in YAML.
• Namespaces, RBAC, and images are correct for the target environment.
• Health checks and logs are in place before promotion.
