rohitg00 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")
