Kubernetes Storage

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 get_storage_classes

2 Check PVC status before pod deployment HIGH describe_pvc

3 Review access modes for multi-pod access MEDIUM get_pvcs

4 Monitor PV reclaim policy LOW get_persistent_volumes

Quick Reference

Task Tool Example

List PVCs get_pvcs

get_pvcs(namespace)

PVC details describe_pvc

describe_pvc(name, namespace)

Storage classes get_storage_classes

get_storage_classes()

List PVs get_persistent_volumes

get_persistent_volumes()

Persistent Volume Claims (PVCs)

get_pvcs(namespace="default")

describe_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 """)

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

Storage Classes

get_storage_classes()

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

get_persistent_volumes()

describe_persistent_volume(name="pv-001")

Volume Snapshots

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

describe_pvc(name="my-pvc", namespace="default")

get_events(namespace="default") describe_pod(name="my-pod", namespace="default")
