使用kubectl-mcp-server的存储工具管理Kubernetes存储。

When to Apply

适用场景

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"

在以下场景使用该技能：

Priority Rules

优先级规则

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`

优先级	规则	影响程度	工具
1	创建PVC前验证存储类是否存在	严重	`get_storage_classes`
2	部署Pod前检查PVC状态	高	`describe_pvc`
3	检查多Pod访问的访问模式	中	`get_pvcs`
4	监控PV回收策略	低	`get_persistent_volumes`

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()`

任务	工具	示例
列出PVC	`get_pvcs`	`get_pvcs(namespace)`
PVC详情	`describe_pvc`	`describe_pvc(name, namespace)`
存储类列表	`get_storage_classes`	`get_storage_classes()`
列出PV	`get_persistent_volumes`	`get_persistent_volumes()`

Persistent Volume Claims (PVCs)

持久卷申请（PVC）

python

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")

python

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

存储类

python

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
""")

python

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

持久卷（PV）

python

get_persistent_volumes()

describe_persistent_volume(name="pv-001")

python

get_persistent_volumes()

describe_persistent_volume(name="pv-001")

Volume Snapshots

卷快照

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
""")

python

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