Kubernetes Storage

Kubernetes storage management for PVCs, storage classes, and persistent volumes. Use when provisioning storage, managing volumes, or troubleshooting storage issues.

Manage Kubernetes storage using kubectl-mcp-server's storage tools.

When to Apply

Use this skill when:

• User mentions: "PVC", "PV", "storage class", "volume", "disk", "storage"
• Operations: provisioning storage, mounting volumes, expanding storage
• Keywords: "persist", "data", "backup storage", "volume claim"

Priority Rules

Priority	Rule	Impact	Tools
1	Verify storage class exists before PVC	CRITICAL	kubectl_get
2	Check PVC status before pod deployment	HIGH	kubectl_describe
3	Review access modes for multi-pod access	MEDIUM	kubectl_get
4	Monitor PV reclaim policy	LOW	kubectl_get

Quick Reference

Task	Tool	Example
List PVCs	kubectl_get	kubectl_get(resource_type="pvc", namespace)
PVC details	kubectl_describe	kubectl_describe(name, namespace)
Storage classes	kubectl_get	kubectl_get(resource_type="storageclasses")
List PVs	kubectl_get	kubectl_get(resource_type="pv")

Persistent Volume Claims (PVCs)

python

kubectl_get(resource_type="pvc", namespace="default")

kubectl_describe(resource_type="pvc", name="my-pvc", namespace="default")

kubectl_apply(manifest="""
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: my-pvc
  namespace: default
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
  storageClassName: standard
""")

delete_resource(resource_type="pvc", name="my-pvc", namespace="default")

Storage Classes

python

kubectl_get(resource_type="storageclasses")

kubectl_apply(manifest="""
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: fast-ssd
provisioner: kubernetes.io/gce-pd
parameters:
  type: pd-ssd
reclaimPolicy: Delete
volumeBindingMode: WaitForFirstConsumer
""")

Persistent Volumes

python

kubectl_get(resource_type="pv")

kubectl_describe(resource_type="pv", name="pv-001")

Volume Snapshots

python

kubectl_apply(manifest="""
apiVersion: snapshot.storage.k8s.io/v1
kind: VolumeSnapshot
metadata:
  name: my-snapshot
  namespace: default
spec:
  volumeSnapshotClassName: csi-snapclass
  source:
    persistentVolumeClaimName: my-pvc
""")

kubectl_apply(manifest="""
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: restored-pvc
spec:
  dataSource:
    name: my-snapshot
    kind: VolumeSnapshot
    apiGroup: snapshot.storage.k8s.io
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
""")

Troubleshooting Storage

python

kubectl_describe(resource_type="pvc", name="my-pvc", namespace="default")

kubectl_get(resource_type="events", namespace="default")
kubectl_describe(resource_type="pod", name="my-pod", namespace="default")
