我的 PersistentVolumeClaim 不会绑定到 NFS PersistentVolume——我做错了什么？

Question

我的 PersistentVolume 配置如下：

apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv0001
spec:
  capacity:
    storage: 5Gi
  volumeMode: Filesystem
  accessModes:
    - ReadWriteOnce
  nfs:
    path: /volume2/K8s_NFS
    server: 172.16.66.50
  persistentVolumeReclaimPolicy: Recycle

我的 PVC 是这样配置的：

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: nfs-claim1
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 5Gi

这似乎与我匹配，但结果是它没有绑定：

Name:          nfs-claim1
Namespace:     default
StorageClass:
Status:        Pending
Volume:
Labels:        <none>
Annotations:   <none>
Finalizers:    [kubernetes.io/pvc-protection]
Capacity:
Access Modes:
VolumeMode:    Filesystem
Used By:       <none>

  Normal  FailedBinding  86s (x26 over 7m33s)  persistentvolume-controller  no persistent volumes available for this claim and no storage class is set

我已确认我集群中的所有三个节点都可以装载该卷。我错过了什么？

您必须在规范中定义 storageClassName，它将用于将 PersistentVolumeClaim 请求绑定到 PersistentVolume。

更新配置，持久卷：

apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv0001
spec:
  storageClassName: manual
  claimRef:
    name: nfs-claim1
  capacity:
    storage: 5Gi
  volumeMode: Filesystem
  accessModes:
    - ReadWriteOnce
  nfs:
    path: /volume2/K8s_NFS
    server: 172.16.66.50
  persistentVolumeReclaimPolicy: Recycle

持久卷声明：

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: nfs-claim1
spec:
  storageClassName: manual
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 5Gi
